Printed Circuit Board Basics

Most of us are using Printed Circuit Board in our daily life. Printed Circuit Boards are used in almost all the Electronic products, from consumer gadgets such as PCs, tablets, smartphones, and gaming consoles to industrial and even high tech products in strategic and medical electronics domains.

Here, we have some statistics for you that shows how many electronic devices connect worldwide from 2015 to 2025. This statistic shows an increase in the use of a number of PCB in people daily life. Hence, CircuitWala took this opportunity to provide a basic knowledge about PCB via this article.

There are so many books available online which teach about Printed Circuit Board design and hardware part. There are few links available online which shows only a few basic fundamentals of PCB and few are there for Basics of Printed Circuit Board (PCB) Design. Few which gives good know knowledge on Printed Circuit Board terminology. But in the end for the hobbyist, there is no such material available which make their work easy.

Now days there few online designing websites available which allow hobbyist and students to create their design and Printed Circuit Board fabrication part. These websites provide limited features and charge high for the full edition. We, @CircuitWala are in try to provide one platform which provides plenty of Printed Circuit Board knowledge digitally to make your work simple and easy.

Alternatives of PCB include wire wrap and point-to-point construction. Creating a layout of PCB is a little bit time-consuming method as compared to its alternative solution but manufacturing of PCB is cheaper and faster then other wiring methods as electronic components are mounted and wired with one single part.

Let’s start with some basics of Printed Circuit Board with this article. Here in this article we will discuss about history of PCB to understand the emerge of PCB, Types of PCB to make your complex PCB a very simple using different types, Usage of PCB to provide you an idea to create more Printed Circuit Board projects, Advantages and Disadvantages, Possible Future to know about new technological change in Printed Circuit Board manufacturing and also about how to destroy and manage your PCB’s e-waste? We know you are eager to know all the stuff in details but before that let’s make a simple definition of Printed Circuit Board.

What is Printed Circuit Board?Printed Circuit Board is an electronic device made of conductive material(FR-4) like copper which connects components mounted on it to to get desired output by providing an input on another end.

When the board has not mounted with any of the components is called as Printed Circuit Board or Printed Wired Board. Mounting of an electronic component on Printed Circuit Board is called as PCB assembly.

History of Printed Circuit BoardThe invention of Printed Circuit Board was by Austrian engineer Paul Eisler as part of a radio set while working in England around 1936.

In early days before Printed Circuit Board became common in use, Point-to-Point construction was used. This meant some bulky and unreliable design that required plenty of sockets and regular replacement of it. Most of this issue directly address when PCB went into regular production.

Originally, every electronic component had wire leads, and the PCB had holes drilled for each wire of each component. The components’ leads were then passed through the holes and soldered to the PCB trace. This method of assembly is called Through-Hole construction. There is one other method to mount component is called as Surface Mount.

Type of Printed Circuit BoardPCBs are produced from the different types of material and on the basis of that material PCBs are divided mainly into two parts: Rigid PCB and Flexible PCB. Nowadays, a combination of Rigid and flexible PCB is also possible and that is called as Flexi-Rigid PCBs.

Most of the PCBs are built in layers. The inner layer is the base material called as a substrate. Rigid PCBs are mainly made of material like epoxy materials and Flexible PCBs are made of plastic material that can withstand high temperatures.

Rigid PCBs are generally, hard materials that hold the component in a better way. The motherboard in the tower of a computer is the best example of Rigid PCBs. Flexible PCBs fundamental material allows PCB to fit into forms that Rigid PCBs can not. Flexible PCBs can turn round without harmful the circuit on PCB.

All Rigid and Flexible PCBs can come in three formats by layers: Single Layer, Double Layer, and Multi-Layer.

1. Single Layer PCBSingle Layer PCBs have been around since the late 1950s and still dominate the world market in sheer piece volume. Single Sided PCBs contain only one layer of conductive material and are best suited for low-density designs. Single-sided PCBs are easy to design and quick to manufacture. They serve as the most lucrative platform in the industry.

2. Double Layer PCBDouble Layered printed circuit board technology is conceivably the most popular type of PCB in the industry. Double Sided PCB (also known as Double-Sided Plated Thru or DSPT) circuits are the gateway to advanced technology applications. They allow for a closer (and perhaps more) routing traces by alternating between top and bottom layers using vias.

3. Multi Layer PCB

Multilayer PCB is a circuit board that has more than two layers. Unlike a Double-Sided PCB which only has two conductive layers of material, all multilayer PCBs must have at least three layers of conductive material which are buried in the center of the material.

Usage of Printed Circuit BoardBy reading this article till this point, we hope that you are now able to get about printed circuit boards. Now, we will make you understand about different applications of printed Circuit Board.

In this digital world, Printed Circuit Board is in almost all our daily life electronic devices and in our industrial electronics as well. Below are the industries where PCBs are used:

Possible FutureNowadays, most of the circuits are replaced to produce Printed Circuit Board from the old methods. Revolution in technology made many of the processes automated and hence it is easy to manufacture PCB. But still, these processes are a bit expensive to hire, involve toxic waste and use high temperatures and acids. With technological advances we have seen in the past years, it is not hard to imagine PCB will soon be revolutionized. Not only that but research institutes predict a more ‘green’ future for PCBs; PCBs being made of paper.

Electronic Waste (e-waste)Electronic Waste or e-waste is described as discarded electrical or electronic devices. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution.

Electronic scrap components contain a hazardous substance such as lead, cadmium, beryllium, or brominated flame retardants. Recycling and disposal of e-waste may involve significant risk to health of workers and communities in developed countries and great care must be taken to avoid unsafe exposure in recycling operations

Nowadays, developing countries are encouraging electronic users to take care while recycling the e-waste or submit them to the organization who are involved in such activities.

SummaryIn this blog, we have learned the basics of Printed Circuit Board. CircuitWala is planning to write as many blogs to provide more and more knowledge of Printed Circuit Board. Either it is basics or manufacturing or usages or advantages and disadvantages of PCBs. We will also try to make our users/customers up to date for the new technology innovations, including past histories and revolution of the PCB industries.

In the next blog, we will look at more briefly about the different types of Printed Circuit Board. We also understand the process to make it and different usage and application for the same.

I bought an 8bitdo Retro mechanical keyboard!

(Picture not mine, source from PC World.)

I wanted a plastic keyboard, I really do not actually use the knob on a Keychron board I have, it still comes in a scooped keycap profile, and it has a companion numpad with a calculator built in. Win/win/win!

This keyboard comes in four designs (not colorways, full designs) themed after the NES, the Famicom, the IBM Model M, and the Commodore 64 keyboard. The NES keycaps have multiple different fonts on them, the Famicom keycaps have Japanese sublegends, the Model M keycaps have a mock stepped Caps Lock key, and the Commodore 64 keycaps are an apparently off-the-shelf SA set from one of many, many, many keycap companies floating around China (I recognize their font and profile shape from Akko ASA keycaps and numerous other scooped profile keycap sets you can have cheaply off of Aliexpress and Amazon. Do check those out, genuinely, you'd struggle to find a bad scooped keycap set these days and I love scooped profiles over Cherry and OEM.)

The build quality of the actual keyboard itself is good, feels like a very similar plastic blend to what 8bitdo uses for its controllers like their Pro 2. Stabilizers are smooth and don't rattle, the legends on the keycaps are reasonably sharp and in NES-appropriate font, the keycaps themselves are MDA profile (I would prefer SA, but beggars can't be choosers) and are somewhat thin but still good quality, dye-sublimated PBT, no warp on the spacebar. Arrow keys are a separate color from the two tones that make up the main keycap set and made to resemble a d-pad. The keyboard itself is somewhat light, but my perception is skewed from using a metal keyboard for a long time, and this is after all a plastic shell, top-mounted keyboard. Even so I think I'll probably end up cracking open the keyboard and putting in some liquid silicone as noise-dampening and additional weight.

Two knobs control both wireless functionality and computer software volume, the wireless knob is heavy with only three options while the volume one is light with many individual steps. The volume knob can be somewhat unresponsive on individual steps. Bluetooth is very responsive and wants to pair with my computer the moment it's flicked over to, and 2.4ghz wireless comes with a receiver that slots into the back of the keyboard magnetically for storage. A power light on the right of the keyboard mimics the NES power light and pulses while charging, is steady while using wireless or when fully charged and connected over USB.

The underlying PCB is south-facing hotswap sockets (who the hell cares their orientation, this only matters for lighting, which this keyboard doesn't have). By default the keyboard comes with Kailh box whites, a very light clicky switch. I yanked them out immediately and put Boba U4T tactiles in because they're the king of all switches. They thunk nicely in this chassis, the Kailh whites weren't slouches either, they did pick a good stock choice for switch without resorting to Gateron or Outemu blue horseshit.

The NES version of the keyboard came with a two-button macro pad that hooks over TRRS cable (you recognize it as a 3.5mm jack or headphone cable) to one of four ports on the top-right of the keyboard. These are essentially just two keyboard switches with giant keycaps on a separate board and the buttons are populated by Gateron greens. The switches are nowhere close to heavy enough to approximate a button, and I gave them Kailh box navies. Still not enough, but better.

These keyboards also come wiiiiiith a companion number pad!

(Picture credit the 8bitdo store.)

While I don't actually have this one in hand just yet I do have it on order. It looks like it'll be about the same build quality as the main keyboard, and it caught my eye for four reasons and ended up making me purchase the full set as a result:

The numpad has a built in calculator.

Same aesthetic choices as the main keyboard (NES, Famicom, IBM Model M, Commodore 64)

Magnetically attaches to the right side of the keyboard to transform it into a more era appropriate full-size.

Far and away the cheapest wireless mechanical numpad with calculator on the market, sitting at $45.

An important note though is that the Famicom and NES keypads don't attach to their respective keyboards, simply because their respective keyboards don't have magnets inside the sides of the chassis to allow for it. I have some cheap button magnets laying around that I'll use for this purpose and probably see if they're strong enough to be placed on the inside of the board and allow for the numpad to connect to it. I also imagine there's going to be a repop or v2 of this keyboard in the future that has this done already, seeing as the Commodore 64 version of the board and I believe the Model M version of the board already have that.

I'll reblog this and give some actual definitive thoughts on the numpad once it's in my hands.

As far as the board itself is concerned, I quite like it. The keycap profile is agreeable, the nostalgia pandering targeted me with laser precision, the board sounds quite good acoustically (especially for being a top-mount keyboard!) and it has a volume knob I'll see if I can reprogram some day. While I normally hate TKL layouts, I'm putting up with it because it will eventually be a fullsize with the numpad. Worth $150 total? Don't know, can't answer that for you, it's worth it to me but I very specifically wanted a keyboard themed after an old Nintendo console with no setup required and no chasing down or commissioning GMK keycap sets. I also wanted a calculator numpad.

Sorry if you've already answered this but being a bit of a tech nerd I have to ask: how do the in-card-pacitators "scientifically" work?

okay, oh boy, my moment is here! /j

I'm sorry it took me so long to answer, I started working on a reply, saved it as a draft, and then it got buried 🥲 but I got a shovel and started digging, so here I am, several months later, with an answer!

It's long, so I put it under a read more ^^

Before I go into it, I am very much an electronics amateur and it's been a minute since I studied circuits in school, so a lot of the gaps in the "science" I filled with magic, so. Take it with a grain of salt.

The basic concepts behind the in-card-pacitators were inspired by two things: those pens that were really popular at one point that allowed you to "draw" circuits and PCBs on paper with electrically conducive ink; and static shock. I like the fan theory that ectoplasm conducts electricity really well, and since Danny has drawn sigils with ectoplasmic paint, I figured he could marry science and sigils again with the cards. If ectoplasm conducts electricity well, it seemed logical to conclude that ectoplasm is full of ions.

The show doesn't really go into how overshadowing "works", so I came up with my own explanation. When a ghost tries to overshadow someone, they have to extend their 'ectoplasmic field' and take over the electric synapses of the person's brain they're trying to control. Assuming ectoplasm operates on a different layer of reality, the electromagnetic field is an area of overlap between 'ghost stuff' and 'not ghost stuff'.

One more thing that has been touched on but not thoroughly explained in IYGABAB-verse is that: 1)ectoplasm is ectophilic; unbound ectoplasm is prone to sticking to larger sources (like: ghost cores, ectoplasm rifts, sigils, etc); and 2) ecto-ice is particularly attractive to ectoplasm; it has a "purifying" effect, but in practice this means it acts like an ecto-magnet. (important to note that although ice and ecto-ice share many qualities, like being cold and being less dense than the liquid state, ecto-ice is not actually ice, and therefore possesses qualities that ice does not have)

Okay. So all that is base level. Going back to the cards and how they work, the most important question is: how are they 'powered'? Where does the shock come from?

The idea here is inspired by static shock and what causes it. I know it's different from AC/DC electricity, so that's where ectoplasm does the heavy lifting. Because most humans don't have their own ecto-field, they wouldn't generate ecto-static (which in this case would be the transfer of ions from one ectoplasmic object to another when they rub against each other, like socks and carpet. But ghost!). Basically, the "capacitors" in the cards are made of ecto-ice, which collect these negatively charged ions, and when a ghost tries to exert their ecto-field on a person holding the card, the circuit connects and the ions jump to the ghost. Boom. They're shocked. Not unlike when you touch two charged capacitors together (to anyone reading this who doesn't know: don't do that. It's dangerous)

So that's basically how they work, and any gaps that make that not make sense scientifically....well no one really understands how magnets work, right? Blame the magnets.

What is PCB Assembly ?

PCB Assembly manufacturer - Hitech Circuits Co., Limited

 It’s the step in the manufacturing process in which you populate a blank board with the electronic components needed to make it into a functional printed circuit board. It’s these components that make a board into the circuit that enables an electronic product to function. PCB assembly typically takes place via one of two processes:

1. Surface-mount technology

SMT: SMT stands for “Surface Mount Technology���.  The SMT components are very small sizes and comes in various packages like 0201, 0402, 0603, 1608 packages for resistors and capacitors. Similarly for Integrated circuits ICs we have SOIC, TSSOP, QFP and BGA.

The SMT components assembly is very difficult for human hands and can be time taking process so it is mostly done by automated pick and place machine.

2. Through-hole manufacturing

THT: THT stands for “Through hole Technology”. The components with leads and wires, like resistors, capacitors, inductors, PDIP ICs, transformers, transistors, IGBTs, MOSFETS are example.

The component has to be inserted on one side of PCB and pulled by leg on other side and cut the leg and solder it. The THT components assembly is usually done by hand soldering and is relatively easy.

Printed Circuit Board Assembly Techniques

There are only two common PCBA techniques available for use by a PCB designer. The methods are:

1. Automated PCB Assembly Techniques

Generally, this technique employs the use of state of the art machines, which are fully automatic. For example, the surface mount components are worth positioning with the aid of an automated pick and place machine.

Again, reflow soldering is commonly for surface mount components usually done in a reflow oven. An automated solder stencil is also used to apply the solder paste on the PCB.

Finally, high tech inspection machines are used to confirm and check the quality of the PCBA. Some of which include: Automated optical inspection machine (AOI), X-ray inspection machines, etc.

Above all, due to the precise monitoring, control of soldering, no human input and versatile machines.

This technique ensures utmost efficiency, output consistencies, and limits defects.

2. Manual PCB Assembly Techniques

This method is favorite for use with through-hole parts, which needs manual placement on the board. Besides, with these through-hole parts, it’s advisable you use wave soldering. Note that in the through- hole assembly process, you need to place the components and electronics on the PCB.

After that, you use wave soldering to solder the leads. Typically, you will need an individual to insert a component into a marked PTH. Once done, transfer the PCB to the next station where the next person will be on standby tasked with fixing another part.

What are the Benefits of SMT PCB Assembly?

SMT assembly provides many benefits and some of them are as follows:

It can be used to incorporate small components.

In SMT, the components can be placed on both sides of the board.

It assures high component densities.

Fewer holes need to be drilled for surface mounting than through-hole.

It require low initial costs and time for setting up the mass production.

SMT is the simpler and faster-automated assembly when compared to through-hole.

Errors regarding the component placement can be easily rectified. 

Surface mount  PCBs feature strong joints, which can easily withstand vibrations. 

What are the techniques used in Surface Mount Technology?

There are several techniques for the reflow process. After applying the solder paste or a flux mixture on the board and after placing the components, the boards are conveyed to a reflow soldering oven. The techniques used for reflowing soldering include infrared lamps, hot gas convection, fluorocarbon liquids with a high boiling point, and so on.

What are the different testing methods used in SMT PCB Assembly?

Hitech Circuits as the PCB assembly manufacturer, we perform the following testing and inspection to ensure the quality of surface mount PCBs.

Automated Optical Inspection (AOI): This is performed before and after the soldering to identify the component placement, presence, and solder quality.

X-ray Testing: In this type of testing, the operator relies on the X-ray images of the PCB to check the solder joints and lead-less components such as Quad Flat Packs and ball grid arrays, which are generally not visible to naked eyes.

In-Circuit Testing (ICT): This method is used to detect manufacturing defects by testing the electrical properties in the SMT Assembly.

What type of files or documents should I send for SMT PCB Assembly? 

Gerber Files: The file contains all details of physical board layers including solder masks, copper layers, drill data, legends, and so on.  

Bill of Materials (BOM): This contains information on the list of items needed for the PCB manufacturing and the instructions of manufacturing. 

Pick and Place File: This file contains information on all components to be used in the PCB design and their rotation and X-Y coordinates.

The whole process of PCB Assembly

1. Bare board loader machine

The first step in the PCB assembly is to arrange the bare boards on the rack, and the machine will automatically send the boards one by one into the SMT assembly line.

2. Printing solder paste

When PCB on the SMT production line, firstly, we have to print solder paste on it, and the solder paste will be printed on the pads of the PCB. These solder pastes will be melt and solder the electronic parts to the circuit board when it passes through the high-temperature reflow oven.

In addition, when testing new products, some people will use film board/adhesive cardboard instead of solder paste, which can increase the efficiency for adjusting the SMT machines.

3. Solder paste inspection machine(SPI)

Since the quality of solder paste printing is related to the quality of welding of subsequent parts, some SMT factories will use optical machine to check the quality of solder paste after printed the solder paste in order to ensure stable quality. If there any poorly printed solder paste board, we will wash off the solder paste on it and reprint, or remove the excess solder paste if there is redundant solder paste on it.

4. High speed SMT machine

Usually, we will put some small electronic parts (such as small resistors, capacitors, and inductors) to be printed on the circuit board first, and these parts will be slightly stuck by the solder paste just printed on the circuit board, so even if the speed of printing is very fast and the parts on the board will not fall away. But large parts are not suitable for use in such high speed SMT machines, which will slow down the speed of small parts assembly. And the parts will be shifted from the original position due to the rapid movement of the board.

5. Universal SMT machine

Universal SMT machine is also known as "slow machine", it will be assembled some large electronic components, such as BGA IC, connectors, etc., these parts need more accurate positions, so the alignment is very important. Use a camera to take a picture to confirm the position of the parts, so the speed is much slower than High speed SMT machine we taked before. Due to the size of the components here, not all of them are packed in tape and reel, and some may be packed in trays or tubes. But if you want the SMT machine to recognize the trays or tube-shaped packaging materials, you must configure an additional machine.

Generally, traditional SMT machines are using the principle of suction to move electronic parts, and in order to place the parts successfully, and there must be the flat surface on these electronic components for the suction nozzle of the SMT machine to absorb. However, for some electronic parts don’t have a flat surface for these machines, and it is necessary to order special nozzles for these special-shaped parts, or add a flat tape on the parts, or wear a flat cap for thees electronic parts.

6. Manual parts or visual inspection

After assembled all parts by the high speed SMT machine or Universal SMT machine and before going through the high-temperature reflow oven, and we will set up a visual inspection station here and to pick out the deviation parts or missing components boards etc., because we have to use a soldering iron to repair if there are still defectives boards after passing the high-temperature oven, which will affect the quality of the product and will also increase the cost. in addition, for some larger electronic parts or traditional DIP parts or some special reasons cannot be processed by the SMT machine before, they will be manually placed on pcb here.

7. Reflow oven

The purpose of reflow oven is to melt the solder paste and form a non-metallic compound on the component feet and the circuit board, that means to solder electronic components on the circuit board. The temperature rise and fall curves often affect the soldering quality of the entire circuit board. According to the characteristics of the solder materials, usually the reflow oven will set the preheating zone, soaking zone, reflow zone, and cooling zone to achieve the best soldering effect.

For example, the melting point for SAC305 solder paste with lead-free is about 217°C, which means that the temperature of the reflow oven must be higher than the melting points to remelt the solder paste. What's more, the maximum temperature in the reflow furnace should not exceed 250°C, otherwise many parts will be deformed or melted because they cannot withstand such a high temperature.

Basically, after the pcb passed through the reflow oven, the assembly for the entire circuit board is almost complete. If there are hand-soldered parts, we need to transfer to DIP process, and then we have to check the quality after reflow oven by QC department.

8. Automatic optical inspection(AOI)

The main purpose of setting up AOI is because some high density boards can’t be process the following ICT test, so we used AOI inspection to replace it. But even using AOI inspections, there still have the blind spots for such checking, for example, the solder pads under the components cannot be checked by AOI. At present, it can only check whether the parts have side standing issue, missing parts, displacement, polarity direction, solder bridges, lack of soldering etc., but cannot checking the BGA solderability, resistance value, capacitance value, inductance value and other components quality, so far AOI inspection can’t completely replace ICT test.

Therefore, there is still some risk if only AOI inspection is used to replace ICT testing, but ICT test is also not 100% make sure the good quality, we suggest these two ways can be combined with together to make sure the good quality.

9. PCB unloader machine

After the board is fully assembled, it will be retracted to the unloder machine, which has been designed to allow the SMT machine to automatically pick and place the board without damaging the quality for PCB.

10. Visual inspection for finished products

Normally there will be a visual inspection area in our SMT production line whether there is an AOI station or not, and it will help to check if there are any defectives after completed assembled the pcbs. If there is an AOI station, it can reduce the visual inspection worker on our SMT line, and to reduce the potential cost, and because it is still necessary to check some places that cannot be judged by AOI, many SMT factories will provide the mainly visual inspection templates at this station, which is convenient for visual inspection worker to inspect some key parts and polarity for components.

11. DIP process

DIP process is a very important process in the whole PCBA processing, and the processing quality will directly affect the functional for PCBA boards, so it is necessary to pay more attention to the DIP process. There are many preliminary preparations for DIP process. The basic process is to re-process the electronic components first, like to cut the extra pins for some DIP components, our staff received the components according to the BOM list, and will check whether the material part numbers and specifications are correct or not, and performs pre-production pre-processing according to the PCBA samples. The steps are: Use various related equipment (automatic capacitor pins cutting machine, jumper bending machine, diode and triode automatic forming machine, automatic belt forming machine and other machines) for processing.

12. ICT test

Printed Circuit board open/short circuit test (ICT, In-Circuit Test), The purpose of ICT test is mainly to test whether the components and circuits on the printed circuit board are open or short issues. It can also measure the basic characteristics of most components, such as resistance, capacitance, and inductance values to judge whether the functions of these parts are damaged, wrong parts or missing parts etc. after passing through the high-temperature reflow oven.

ICT test machines are divided into advanced and basic machines. The basic ICT test machines are generally called MDA (Manufacturing Defect Analyzer). It’s just to measure the basic characteristics of electronic components and judge open and short circuits issue we talked above.

In addition to all the functions of the basic ICT test machines, for advanced ICT test machine can also test the whole PCBA by using power, start to testing the PCBA boards by setting the program in the test machine. The advantage is that it can simulate the function of the printed circuit board under the actual power-on condition, this test can partly replace the following functional test machine (Function Test). But the cost for the test fixture of this advanced ICT test can probably buy a car, it’s too expensive and we suggest it can be used in mass production products.

13. PCBA function test

Functional testing is to make up for the ICT test, because ICT only tests the open and short circuits on the the PCBA board, and other functions such as BGA and other fuctions are not tested, so it is necessary to use a functional testing machine to test all functions on the whole PCBA board.

14. Cutting board (assembly board de-panel)

Normally, printed circuit boards will be produced in panel, and it will be assembled to increase the efficiency of SMT production. It means several single boards in one panel, such as two-in-one, four-in-one etc. After finished all the pcb assembly process, it needs to be cut into single boards, and for some printed circuit boards with only single boards also need to cut off some redundant board edges.

There are several ways to cut the printed circuit board. You can design the V-cut using the blade cutting machine (Scoring) or directly manually break off the board (not recommended). For more high density circuit boards, it will be used the professional splitting machine or the router to split the board without any damage the electronic components and printed circuit boards, but the cost and working hours will be a little longer.

Moisture sensor development - 2022/23

Multiple sensors have been running over winter 22 to summer 23 and some problems have arisen:

One temperature sensor stopped functioning but in a way that eluded the error detection. The symptom was that the two sensors showed exactly the same measurement. This turned out to be a configuration issue, where both sensor were mapped to the same temperature.

Battery life was too short on a couple of sensors. This may be because of poor quality batteries, poor connections in the battery holder or due to excess drain somewhere. After experimentation with better quality batteries (Samsung 25R rated at 2500 mAh) it seems the main problem is poor quality batteries.

Moisture sensors losing discrimination. On a new sensor the range from wet to dry is typically 900 but this reduced to 270. I found that cleaning off the old silicon sealant, cleaning the board and resealing brought the readings back to normal.

Moisture sensor connection. The waterproofing with silicon and the JST connector are a poor design. Securing this connector with a zip tie helps to secure this connector.

Rusty main board. One device failed due to rust getting into the pins and socket on the main board connector. This is evidence of moisture in the device container. The sensor cable entrance is sealed with a large amount of silicon sealant which often fails. However when a second device also failed, having drained new , quality batteries very quickly, it seems that the idea of using socket strips on an outdoor device, however well sealed, is a mistake. In any case the board and the chip are really the only significant components so they may as well be soldered together.

One sensor on a public Tiny Forest was stolen. This despite being well - hidden and having a notice inside the box explaining the scientific purpose of the device.

I had considered changing the design of the PCB to avoid the use of a ground plane since I found this made soldering to ground terminals difficult and poor connections created problems. On reflection, my problem is probably insufficient thermal inertia in my small iron and the use of a better, temperature-controlled iron would solve this issue whilst retaining the benefits of a ground plane.

Labels printed on a label printer fade very quickly in sunlight.

An error in the code for the test phase meant that sleep time could be negative with odd results.

It has been suggested that over-the-wire updating of the code should be implemented but I am concerned about the current demand,

Improvements

Have a working set of all three sensors which can be plugged into a device to check the cause of a failed sensor.

Replace the cheap 18650 batteries with Samsung 25R flat top batteries.

Solder the chip directly to the PCB instead of using a socket strip

Develop a better sealing system for the cable entry.

Use a chinagraph pen for labeling

Reconsider strategy for protecting devices in public places
