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.

Understanding Circuit Board Electronic Components: A Comprehensive Guide

In today's digital world, electronic devices have become an essential part of our daily lives. But what makes these devices tick? At the heart of every electronic device lies a circuit board—a masterpiece of tiny electronic components working together to perform complex tasks. In this article, we’ll dive deep into the fascinating world of circuit board electronic components, exploring each element’s role and how they contribute to the overall functionality of the device.

What is a Circuit Board?

A circuit board, often referred to as a PCB (Printed Circuit Board), is a flat board used to mechanically support and electrically connect various electronic components. These components work in unison to perform a specific task. Think of the circuit board as the skeleton and nervous system of an electronic device—it holds everything together and allows communication between parts.

Types of Circuit Boards

Single-sided PCB: Has one layer of conducting material.

Double-sided PCB: Contains two layers for components and connections.

Multi-layer PCB: Complex boards with multiple layers for advanced applications.

The Role of Electronic Components on a Circuit Board

Every electronic device you interact with is powered by a carefully designed circuit board filled with various components. These components might be tiny, but each one has a critical role in the operation of the device. Here's a breakdown of the most important electronic components you’ll find on a typical circuit board.

1. Resistors

Resistors are fundamental components that control the flow of electrical current. They resist the flow of electrons, hence the name "resistor." Their primary function is to reduce current flow, adjust signal levels, and divide voltages in a circuit. Without resistors, circuits would allow too much current to flow, potentially damaging other components.

Types of Resistors

Fixed resistors: Have a set resistance value.

Variable resistors: Allow adjustment of the resistance.

2. Capacitors

Capacitors store and release electrical energy in a circuit. They are often compared to small rechargeable batteries that quickly charge and discharge. Capacitors help smooth out fluctuations in voltage, filter noise, and store energy for future use.

Common Uses of Capacitors

Energy storage

Signal filtering

Voltage stabilization

3. Inductors

Inductors are components that store energy in a magnetic field when electrical current flows through them. They resist changes in current and are typically used in circuits to filter signals, manage power, and store energy.

Applications of Inductors

Power supplies

Radio frequency circuits

Noise suppression in circuits

4. Diodes

A diode is like a one-way valve for electricity, allowing current to flow in only one direction. They are vital in circuits to prevent reverse currents, which can damage components.

Types of Diodes

Light-emitting diodes (LEDs): Produce light when current flows through.

Zener diodes: Regulate voltage within a circuit.

5. Transistors

The transistor is a versatile component used to amplify or switch electronic signals. In essence, transistors are like tiny switches that turn signals on and off rapidly, making them essential in modern electronics.

Types of Transistors

NPN transistors: Allow current flow when a small voltage is applied to the base.

PNP transistors: Conduct when the base is negatively charged.

How Circuit Board Components Work Together

In a circuit, each component has a specific role, and together they form a cohesive system. For example:

Capacitors and resistors may work together to filter signals or smooth out voltage fluctuations.

Transistors and diodes ensure that signals are amplified or directed properly.

Integrated circuits handle the complex tasks, processing data, and controlling the overall system.

Choosing the Right Components for Your Circuit Board

When designing or repairing a circuit board, choosing the correct components is crucial. Some factors to consider include:

Voltage requirements

Power consumption

another new toy

I've been planning to get a number of accessories for my new computer. A new monitor, microphone, maybe one of those vr headsets. But after having it for a few weeks, one thing jumped out as needing an upgrade more urgently than anything else - the stock full size keyboard that came with it was just too large and awkward for my little keyboard shelf. I was tempted to go back to the Microsoft Compact Bluetooth keyboard that I was using with the Steam Deck... but I haven't had a "real" computer, like a proper desktop computer in decades, I wanted a "real" keyboard to go with it. Like a proper mechanical keyboard with switches and buttons and such. And so I typed "mechanical keyboard reviews" into a youtube search, blissfully unaware of the rabbit hole I was about to fall down.

If you know then you already know, but it came as a surprise to me that membrane keyboards are so cheap and so easy to mass produce that they've taken over the casual market altogether, forcing mechanical keyboards into the domain of the ⋆ ˚｡⋆˚enthusiast⋆ ˚｡⋆˚

Yes, it seems proper keyboards are a hobby now, not a very cheap one either, and the very last thing I need is another expensive hobby. But every hobby has its more affordable and approachable on ramps, and there are a number of pre-built budget boards occupying this space in world of mechanical keyboards. After watching a few dozen hours of youtube videos and reading a bunch of reviews and tutorials, I eventually settled on the RK84 'limited edition' from Royal Kludge for us$80. Which is like twice what I expected to pay when I in my naive innocence began shopping for keyboards, but I've come to understand that eighty bucks absolutely counts as "budget" in this hobby.

Pricing aside, I really do love my new keyboard. The 75% form factor is ideal, better centering the typing keys and saving a bunch of extra space on my little shelf while maintaining all the functionality of a full size board save only for the number pad. While I do like to use a number pad, I don't mind taking one out when I need it, and the keyboard even has a couple usb ports to easily plug a mouse and separate number pad into, which is super convenient and such an obvious idea that I really have to wonder why all keyboards aren't doubling as USB multi-dongles at this point, with additional usb ports, sd card ports, and so on.

For $10 more than the regular RK84 wireless, the 'limited edition' version has better keycaps, factory-lubed switches, some filler foam in the housing to reduce the hollow sound, an additional layer of sound dampening foam sandwiched between the top plate and the pcb, and a snazzy color scheme, the version I chose combining a black body and mostly black keys with a white top plate that better reflects the swirly rainbow rgb backlighting. The sound is decent, at least to my untrained ear, right out of the box. Which is ideal, as I'd like to avoid the temptation to start modding it.

Because I've gone about as far down this particular rabbit hole as I want to go.

Though I suppose it is tempting to open it up, as some basic tape & band aid mods would be cheap and easy and might improve the sound a bit...

And as much as the pre-lubed yellow linear switches are nice, I did make sure to get a hot-swappable board so it's easy to change them out later if I want to try alternatives, and I do think I might prefer tactile switches for typing...

And the rgb lighting is nice enough that it really is a shame these caps aren't shine though. Yeah, yeah, shine-through is tacky, but Cringe is Dead, and some black top pudding caps might really make the lighting pop. Or maybe a mix of black, white and some accent color to match the color layout that the board came with?

The abyss, it tempts me so...

Surface Finishes for Multilayer PCBs and Their Impact

Multilayer PCBs are essential in modern electronic systems where high-density routing, signal integrity, and reliability are critical. While inner layers are encapsulated during lamination, the outer layers of a multilayer PCB are exposed for component assembly — making surface finish a key factor in performance and long-term reliability.

Surface finish not only protects the exposed copper but also directly influences soldering quality, component compatibility, and board lifespan, especially in complex multilayer designs.

Why Surface Finish Is Critical in Multilayer PCBs

In a multilayer PCB, especially those with 6, 8, or more layers, outer-layer copper traces and pads are often extremely dense and designed for fine-pitch SMT components such as BGAs, QFNs, or high-pin-count connectors.

A good surface finish must:

Ensure consistent solderability across dense pad arrays

Maintain flatness to support reliable assembly of micro-components

Provide oxidation protection during storage and processing

Be compatible with lead-free reflow profiles

Handle multiple reflow cycles without degradation

Multilayer PCBs often undergo more complex assembly and higher thermal stress, so the surface finish must meet higher standards than simple single- or double-layer boards.

Common Surface Finishes for Multilayer PCBs

1. ENIG (Electroless Nickel Immersion Gold)

The most popular surface finish for multilayer boards, especially in high-density and high-reliability applications.

Provides excellent flatness for fine-pitch components (e.g. BGAs)

Stable during multiple reflow cycles

Compatible with high-speed signals due to smooth surface

Long shelf life, ideal for staged assembly

Slightly higher cost but justified by performance

Widely used in servers, telecom equipment, and aerospace PCBs.

2. OSP (Organic Solderability Preservative)

Preferred for cost-sensitive multilayer boards with fine-pitch components.

Flat surface suitable for automated SMT

Environmentally friendly and lead-free

Lower cost than ENIG

Limited shelf life, requires controlled handling

Not ideal for boards requiring multiple assembly cycles

Often used in consumer electronics and automotive applications.

3. Immersion Silver

Used for multilayer boards requiring high signal integrity or RF performance.

Low surface roughness ensures good impedance control

Suitable for high-frequency multilayer PCBs

Sensitive to tarnishing and handling

Better electrical performance than ENIG in certain designs

Good choice for communication equipment and high-speed digital boards.

4. Lead-Free HASL

Sometimes used in low-cost multilayer boards, but not recommended for very dense designs.

Cost-effective, robust finish

Less flat surface can cause soldering issues on fine-pitch pads

May lead to solder bridging in dense layouts

Acceptable for through-hole or mixed technology boards

Usually applied to industrial control or power-related multilayer PCBs.

Surface Finish Considerations in Multilayer PCB Design

When choosing a surface finish for multilayer PCBs, consider:

Assembly method (SMT vs through-hole, single vs multiple reflows)

Pad density and component type (especially fine-pitch packages)

Signal performance needs (RF, impedance control, etc.)

Environmental factors (RoHS, storage conditions)

Budget vs reliability trade-offs

In many high-reliability or mission-critical multilayer designs, ENIG or Immersion Silver is preferred despite higher cost, due to their consistent performance.

Final Thoughts

The outer layers of a multilayer PCB may seem like a small part of a complex system, but the choice of surface finish can make or break the final product. Whether it's ensuring reliable solder joints for 0.4 mm pitch BGAs, withstanding multiple reflow cycles, or maintaining performance in high-frequency circuits — the right surface finish is critical.

Understanding the relationship between board complexity, material stack-up, and surface treatment is essential for delivering a reliable, high-performance multilayer PCB.

Photolithography: A UV-sensitive photoresist is applied, exposed to UV light, and developed to create the circuit pattern.

Direct Imaging: A laser directly etches the pattern onto the PCB.

4. Etching the Copper Layers

After the circuit pattern is printed, the unwanted copper is removed through chemical etching. The remaining copper forms the conductive traces.

5. Drilling Holes for Components

Precision CNC machines drill holes for through-hole components and vias (connections between layers).

6. Plating and Copper Deposition

The drilled holes are electroplated with copper to ensure conductivity between layers.

7. Solder Mask Application

A solder mask (usually green) is applied to protect the copper traces and prevent short circuits. Openings are left for soldering components.

8. Silkscreen Printing

Text, logos, and component labels are printed on the PCB using silkscreen ink for easy assembly and identification.

9. Surface Finish Application

A surface finish is applied to protect exposed copper and improve solderability. Common finishes include:

HASL (Hot Air Solder Leveling)

ENIG (Electroless Nickel Immersion Gold)

OSP (Organic Solderability Preservative)

10. Electrical Testing and Quality Control

Each PCB undergoes automated optical inspection (AOI) and electrical testing to ensure functionality. Defective boards are rejected.
