Prompt #17, Extra Credit: Blood

“Gun- Gun- Gunslinger- Hawk-” The static came in the middle of hysterical laughter. Raucous. Joyful. Pained.

Weaponsfire seared the air. Plasma scorched even the darkest pieces of the midnight alleys. Circuits and bone and artificial memories screamed in the arching shadows like neon. Copper wiring with magnetic spirals as plasma bolts in magnetic remnants spun by them, electricity in the air that coursed along her skin and down her fingertips. Gunshots. Gunshots. Gunshots. It had just rained. The puddles were evaporating. Water and mineral content changing. Not the acid-tinged rain. Not the runoff filled with particulate plastic and rubber. Iron. Blood. It reverberated with the screaming. With the gunfire. Her fingertips scrabbled as the night drowned out her voice, as the one currently fighting couldn’t turn away. There were so many after all. Where had they come from? No evidence on any network. No trace in the silicon. No touch could elevate her senses into finding them in footage or local magnetic effects. But here they were now, and here they were now. Bullets scraped the sheet metal wall as she finally found it. She tore off the access panel, the metal groaning and screaming in time with the combat. Could it be heard over it all? She could certainly feel it. She could feel the echo of it in every sensor even as they focused on tracking every projectile that rocketed by. How could she feel so powerless in all of this? Certainly she wasn’t made for being a combatant but she had some of the best military tech money could buy put into this body, not even speaking on software- No time, no time, milliseconds were screaming by and signals were closing in. Coming closer, gunfire louder, her combatant charge cursing as she fumbled for ammunition. And then it all went black.

Not for her, no. Far from it. For her? The world couldn’t be clearer. Her tail was jammed straight into the junction box. The entire sector’s power supply at her fingertips. Enough voltage to fry any human so insane, enough current to melt any synthetic that could ever hope to imagine. But for her? The mimicked taste of copper and ozone on her body’s sensors only let her know that her laughter had become laced with the high pitched scream of high voltage.  

Fuses blew, breakers popped, lights went dark, machines fell dead, as all in that moment was hers. All in that moment was made to bend to her, to come to her, to feed her. “Gunslinger.” The AM-3S unit spoke. A voice of one, a chorus of more. “Watch.” And the city came to life under the weight of a mind. Pylons roared into brilliant plasma arcs, neon bulbs sparked and exploded, ancient machinery lost beneath the asphalt screamed through the surface. All of it her hands, all of it her fingertips, all of it bleeding her senses and bleeding her life. The datastream of multitudes as network and networked rose in tandem, as circuit and copper and old-world PCB responded to her just as the body of one did. Human-lethal pressure waves, human-lethal temperature, human-lethal particulate as blood and bone vaporized under the renewed life of a mind that had been confined from ten thousand senses down to one. And still the unit stood close to her gunslinger. A smile on its face. The cables trailing behind it still sparking and frying in the junction box. Further and further the blackout spread. And louder and louder the voltage laughed. Drive off these attackers, protect herself, protect this charge, follow her protocols to the letter and she could have it all. She could have her network, this body, her mind and all that it entailed, she could be free of it all and take what she wanted in this cesspool that she had been born into-

Blackout. Cut off. Her tail snapped back into her body, her mind pulled back as a cord which had stretched too far. Face down in the water. Iron percentage: 34%. Correction, as her last thought plugged through her remaining charge. Face down in the blood.

LED PCB Assembly

What is the LED Circuit Board assembly?

Generally, LED PCB assembly is considered to be a circuit board that has the LED components soldered to it. The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. Not all the PCB products can be used in Led industry, as an LED PCB is easy to create a high volume of heat, but making it hard to cool with traditional methods. For this reason, metal core PCB is widely used in LED application because of their enhanced ability to dissipate heat, especially aluminum pcb is often used to fabricate PCB for LED lights.

We’ve had great LED PCB assembly experiences with top LED chips to brand such as Cree, Luxeon, Osram, Nichia, Lumileds, MLS, EVERLIGHT, Samsung, LG, Seoul., etc. PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility.

LED PCB Assembly specification

Number of layers for LED PCB

These layers are made up of aluminum and magnesium, but now have Copper base material  and Ceramic base materials for LED PCB industry, we can meet it.

Aluminum LED PCBs stand out among other PCBs because it has a good insulation characteristic and has a better machinery performance, the cheap cost is one important factor too.

Types of layers for LED PCB Assembly

Normally, the base layer is made using aluminum alloy metal.

This aluminum alloy substrate used in making the base makes it ideal for through-hole technology which transfers and dissipates heat.

A thermal insulation layer is made using some ceramic polymer which has good viscoelasticity characteristics.

It is highly heat resistant and protects the PCB against heat and mechanical stress.

The circuit layer, which is covered by a copper foil which can range from one to ten ounces.

LED Board type- single or in panel

Some boards are shapeless. For this reason, LED PCB panels are used. This reduces time, labor production and testing time.

Some LED PCB Assembly is done on a single board while others are done on panel boards.

LED PCB Assembly Process

Roughly, the PCBA process can be divided into theses phases: soldering paste printing > SMT (surface mounted technology) > reflow soldering > AOI (automated optical inspection)> THT (through-hole technology) > wave soldering > touch-up and cleaning > IC-programming > FCT (functional tests) > aging testing. 

Below we show you the process.

Step1. Summarizing Project Information

Before contacting your supplier, make sure you have all the project information. Suppliers will need info following for quoting LED PCB assembly:

Gerber

BOM

LED PCB specification

Quotation quantity

Once you have gathered these information, you can contact us and request for a quote.

Of course, you can also provide the schematic, LED PCB Assembly pictures and even samples to us. The more details they have, the more accurate the supplier’s quotation will be.

Step2. Discussion and details about custom LED PCB Assembly

Different projects will have different requirements. Remember the special requirements mentioned in step 1? That’s going to be the focus of this session. Equipment and engineering capacity will not be identical between suppliers. Make sure your supplier has the equipment to produce and assemble major components and the corresponding testing capabilities.

For example, some vendors don’t have X-ray testing equipment, which means they can’t check the mount quality of BGA chips. Outsourcing this step will increase risk and cost. That’s what you don’t want.

Also, pay attention to time taken by the supplier to quote. Motherboards often contain hundreds or even thousands of components, and they are supplied by different manufacturers. To ensure the quality of the components, the supplier sourcing team will make multi-inquiries from these manufacturers or authorized suppliers to match customer’s requirement, which usually takes 2-3 business days, and even longer for some scarce chips. Therefore, if your project is complex and the supplier quotes you within few hours, double check with them.

Step3. Sample and feedback

After confirming the PI, the supplier will usually provide pre-production samples for your approval. At the same time, the supplier will also confirm with you the logistics plan of the bulk goods. Make sure they understand your shipping requirements, including details on packaging, customs clearance, taxes, etc.

For us to have a successful LED PCB Assembly process, its functions must be defined. Compliance requirement is defined to reduce the effect when components are selected.

The Bill of Materials is then generated from the information installed on the LED PCB.

All this information is used to assemble components which are identified from MOB to the LED PCB.

After that, the routing of traces is determined to each component, based on the size, shape of the circuit board and location of connectors.

2. Dry ice pellet machine（Dry Ice Granulator Machine）:

        Dry ice pelletizer is a piece of equipment specially used to turn liquid carbon dioxide (CO2) into solid carbon dioxide (dry ice) pellets.

        Dry ice pelletizers usually deliver liquid CO2 into the machine through a liquid carbon dioxide supply system. Liquid carbon dioxide undergoes a series of cooling and pressurization processes, causing its temperature and pressure to rise. The pressurized liquid carbon dioxide passes through the nozzle or spray head and enters a relatively low-pressure environment. In this environment, liquid CO2 rapidly relaxes and expands, lowering its temperature and turning into a solid state. Because the temperature drops sharply, liquid CO2 turns into a gaseous state and forms tiny CO2 particles, known as dry ice particles.

        The Dry ice machine can efficiently convert liquid CO2 into a large number of evenly distributed dry ice pellets. The advanced control system can achieve precise control of parameters such as temperature, pressure and particle size to ensure the production of dry ice that meets requirements. Some Dry Ice Granulator have adjustable mechanisms that allow the user to select different sizes of dry ice pellets. There is no need to add any chemicals during the manufacturing process, and the waste material is CO2 gas, so the dry ice pelletizer is considered a relatively environmentally friendly production method. Most Dry Ice Pelletizer Making Machine are equipped with automated operation functions, including automatic adjustment and monitoring systems to improve production efficiency.

3. Dry Ice Block Machine（Dry ice briquetting machine）:

        A dry ice block press is a piece of equipment specifically designed to compress dry ice pellets or pieces into block form.

        Dry ice block presses typically use previously produced dry ice pellets or chips as raw material. These pellets or chips are usually prepared through an overhead dry ice pelletizer or other means. Dry ice raw material is transported to the compression zone and heated to a certain level. The purpose of heating is to cause the dry ice pellets or blocks to begin to soften and melt. After heating, the softened dry ice is placed in a compression zone, where compression machinery or a hydraulic system exerts tremendous pressure to compress the dry ice into blocks. The compressed dry ice blocks pass through the cooling system, where they are quickly cooled and re-solidified to form solid dry ice blocks. The formed dry ice blocks enter the collector through the collection system, and then enter the packaging area through the conveyor system for final packaging.

Rain Sensor: Advanced Automotive Safety Technology

What is a Rain Sensor?

A rain sensor is an electro-optical system that uses infrared technology to detect the presence and intensity of precipitation on the windshield. This system is designed according to ISO 11452-9 standards and operates as part of the automatic wiper system.

What is a Rain Sensor in Cars?

The rain sensor is installed behind the central rearview mirror and consists of three key components:

Infrared Light Source: LED with wavelength of 880-940 nanometers

Photodiode Receiver: Detects light reflection from the glass surface

Signal Processing Unit: Analyzes data at a rate of 100 samples/second

The most important capability of the rain and light sensor is its ability to detect raindrops as small as 0.5 millimeters.

How Does a Rain Sensor Work?

The rain sensor operates in four stages:

Emission of light pulses to the external glass surface

Measurement of reflection coefficient with photodiode

Calculation of precipitation intensity based on reflection changes

Sending commands to ECU for wiper speed adjustment

The rain sensor system can distinguish between rain, snow, and water spray from other vehicles.

Benefits of Rain Sensors

Key advantages of rain sensors in cars include:

40% reduction in accident probability during rainy conditions

Automatic wiper speed adjustment from 1 to 6 levels

15% savings in windshield washer fluid consumption

Increased lifespan of wiper blades

Rain Sensor Construction

Rain sensor construction is based on advanced optical and electronic principles. The sensor consists of a light-emitting diode (LED) for projecting infrared light onto the windshield surface and an optical sensor for measuring the amount of reflected light.

Under normal, dry conditions, infrared light is completely reflected from the glass surface. However, when water droplets are present, the light becomes scattered and the amount of reflected light decreases.

These changes are detected by the optical sensor and converted into electronic signals. These signals are then sent to the vehicle's Electronic Control Unit (ECU), which issues commands to activate the wipers.

Modern rain sensors are constructed from these materials:

Lens: Polycarbonate with anti-reflective coating

PCB: Printed circuit fiber with gold plating

Optical Adhesive: UV-Curable epoxy with refractive index of 1.52

Housing: ABS with IP69K protection rating

Rain Sensor Price

The cost of a rain sensor depends on various factors:

Number of optical channels (1 to 3 channels)

Operating temperature range (typically -40 to +85°C)

CAN Bus compatibility

Manufacturer brand (Bosch vs. Valeo)

The current price range for car rain sensors in the Iranian market in 2024 is between 1.2 to 5 million tomans.

Rain Sensor Installation

To install a car rain sensor, the installation location on the windshield is first determined, usually behind the center mirror. The glass surface in this area is then completely cleaned and dried to ensure proper sensor adhesion.

The rain sensor, which includes an electronic module and an optical gel layer, is attached to the glass using special adhesive. After installation, the sensor cables are connected to the vehicle's electronic system, and necessary software settings are performed through diagnostic equipment to properly synchronize the sensor with the wiper systems.

Finally, the sensor's performance is tested under various weather conditions to ensure its proper operation.

Rain Sensor Repair

Rain sensor repair typically involves checking and fixing problems related to its optical and electronic components. If the sensor doesn't work properly, electrical connections and related cables should first be examined.

Additionally, the windshield surface at the sensor installation location must be cleaned of any contamination and scratches. If there are problems with optical components, such as LED or optical sensor, replacement of these parts by experienced specialists is recommended.

In some cases, reprogramming the sensor software or vehicle ECU can resolve operational issues.

Rain Sensor: Integration of Optics and Electronics for Safety

Modern rain sensors with 99% accuracy and 50-millisecond response time have created new standards in active safety systems. Development of this technology is moving toward integration with more advanced systems such as fog detection and automatic headlight adjustment.

Proper maintenance, including periodic lens cleaning and connection inspection, can extend the system's useful life up to 10 years.

Phenomenon: Moisture ingress, fogging inside switch, corrosion.

Cause:

Poor sealing design (e.g., thin O-ring, low contact pressure).

Material aging (e.g., silicone rubber hardening).

Incorrect installation causing compression loss.

Optimization:

Use high-performance fluorosilicone O-rings.

Design mechanical structures that maintain sealing pressure under thermal expansion.

Add secondary sealing like glue filling or ultrasonic welding.

2. Case Studies from Customer Sites

Case A: Food Processing Machine Button Fails after 3 Months

Problem: Button became sticky and unreliable; LED flickered.

Analysis: High humidity and oil vapor caused internal corrosion and solder failure.

Solution: Upgraded to IP68 switch with epoxy-sealed LED and food-grade silicone sealing ring. After redesign, no failure in 6-month follow-up.

Case B: Elevator Call Panel Button Lost Tactile Feedback

Problem: Users reported button was soft and unresponsive.

Analysis: Long-term mechanical fatigue led to spring plate deformation.

Solution: Changed to double-spring structure (coil + dome), added fatigue life test in production. Mechanical cycles improved from 300,000 to 1.2 million.

Case C: Industrial Panel with Intermittent Contact

Problem: Switch signal occasionally failed.

Analysis: Contact surface oxidation due to prolonged storage and lack of current load.

Solution: Switched to gold-plated contacts, added low-current self-cleaning pulse during power-on to ensure reliability.

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.

From smartphones to industrial machinery, PCBs provide the foundation for electrical connections, enabling devices to function efficiently. This guide explores the PCB Manufacturing process, materials used, key technologies, and industry trends.

The PCB Manufacturing Process: Step by Step

The production of Printed Circuit Boards involves multiple stages, each requiring precision and expertise. Below is a detailed breakdown of the PCB Manufacturing workflow.

1. Design and Schematic Creation

Before production begins, engineers design the PCB using specialized software like Altium Designer, Eagle, or KiCad. The schematic defines the electrical connections, while the layout determines the physical placement of components.

2. Printing the PCB Design

Once the design is finalized, it is printed onto a laminate material using a photoplotter, which transfers the circuit pattern onto a film.

3. Substrate Preparation

The base material, typically FR-4 (fiberglass-reinforced epoxy laminate), is cleaned and coated with a photosensitive layer called photoresist.

4. Exposure and Developing

The photoresist-coated substrate is exposed to UV light through the printed film. The exposed areas harden, while the unexposed regions are washed away during the developing stage.

5. Etching the Copper Layers

The board is then immersed in an etching solution (usually ferric chloride or ammonium persulfate), which removes unwanted copper, leaving only the desired circuit traces.

6. Drilling Holes for Components

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

7. Plating and Copper Deposition

A thin layer of copper is electroplated onto the board to strengthen the connections and ensure conductivity.

8. Solder Mask Application

A solder mask (usually green, but available in other colors) is applied to protect the copper traces from oxidation and prevent solder bridges.

9. Silkscreen Printing

Component labels, logos, and reference indicators are printed onto the board using silkscreen printing for easier assembly.

10. Surface Finish Application

To prevent oxidation and improve solderability, a surface finish (such as HASL, ENIG, or OSP) is applied.

11. Electrical Testing and Quality Control

Automated AOI (Automated Optical Inspection) and flying probe testers verify electrical connectivity and detect defects.

12. Final Assembly and Shipping

Once tested, the PCBs are assembled with components (if required) and shipped to manufacturers for integration into electronic devices.

Materials Used in PCB Manufacturing

The quality of a Printed Circuit Board depends heavily on the materials used. Key materials include:

Copper Foil: Conducts electricity and forms the circuit traces.

FR-4 Substrate: Provides mechanical strength and insulation.

Solder Mask: Protects copper traces and prevents short circuits.

Silkscreen Ink: Adds labels and markings for assembly.

Surface Finishes (HASL, ENIG, OSP): Enhances solderability and durability.

Advanced PCB Manufacturing Technologies

As electronics evolve, PCB Manufacturing techniques continue to advance. Some cutting-edge technologies include:

1. High-Density Interconnect (HDI) PCBs

These boards feature microvias, finer traces, and multiple layers, enabling compact designs for smartphones and wearables.

2. Flexible and Rigid-Flex PCBs

Made from polyimide or other flexible materials, these PCBs are used in bendable electronics like foldable phones and medical devices.

3. Multilayer PCBs

With 4 to 50+ layers, these PCBs are essential for complex devices like servers and aerospace systems.

4. Embedded Components

Passive components (resistors, capacitors) are embedded within the PCB, reducing size and improving performance.

5. 3D Printed Electronics

Additive manufacturing is being explored for rapid PCB prototyping, allowing faster design iterations.

Challenges in PCB Manufacturing

Despite advancements, PCB Manufacturing faces several challenges:

Miniaturization: As devices shrink, producing ultra-fine traces becomes difficult.

Signal Integrity: High-speed circuits require precise impedance control.

Thermal Management: Dense PCBs generate heat, necessitating effective cooling solutions.

Environmental Regulations: Restrictions on hazardous materials (lead, halogen) impact manufacturing processes.

Future Trends in PCB Manufacturing

The PCB Manufacturing industry is evolving with new trends:

AI and Automation: Machine learning improves defect detection and process optimization.

Sustainable Manufacturing: Eco-friendly materials and lead-free soldering gain traction.

5G and IoT Demand: High-frequency PCBs are needed for 5G networks and IoT devices.

Additive Manufacturing: 3D printing could revolutionize prototyping and low-volume production.
