PCB Manufacturing Process: All You Need to Know

Creating a printed circuit board (PCB) is a systematic process that begins with meticulous design and material selection, crucial for ensuring functionality and durability. The initial steps involve the application of a thin layer of copper over a substrate material, typically a fiberglass substrate reinforced with epoxy resin and glass fiber, which provides the necessary rigidity and electrical insulation. This copper layer is then patterned to form conductive areas that will eventually carry electrical signals.

The layout design process utilizes advanced CAD software for precision, ensuring that the conductive paths and component placement areas are accurately defined. Once the design is finalized, it's transferred onto the PCB using photo reactive chemicals and UV exposure, a process known as outer layer imaging. This method allows for the precise alignment of layers and the creation of intricate circuit patterns.

After the design transfer, the excess copper is removed through a careful etching process, leaving behind the copper traces that form the circuitry. The PCB then undergoes a laminating process to apply a solder mask, a protective layer that covers the entire board while exposing the areas where components will be soldered. This solder mask application is crucial for preventing short circuits and ensuring the longevity of the PCB.

Following the application of the solder mask, a silkscreen printing process adds labels and markings to the PCB, aiding in component placement and board identification. The final step in the fabrication processes involves applying a surface finish, such as tin plating, to protect the exposed copper and ensure a reliable soldering surface. Other surface finishes like HASL (Hot Air Solder Leveling) or ENIG (Electroless Nickel Immersion Gold) are also used depending on the application requirements.

Throughout the PCB manufacturing process, precision is maintained through the use of technologies like CNC machines for accurate drilling of holes that will accommodate electronic components. Each part of the PCB fabrication process, from the initial design to the final surface finish, is critical to enhancing the PCB's electrical performance and longevity.

The final stages of assembly involve the placement of components onto the PCB, often by a contract manufacturer specializing in PCB assembly. This is followed by soldering, which can be done through various methods, to securely attach the components to the board.

Rigorous electrical tests are conducted to validate the PCB's performance, ensuring that it meets stringent quality standards before integration into electronic devices. These tests verify the integrity of the conductive paths, the correct orientation of components, and the overall functionality of the PCB.

This holistic approach underscores the importance of meticulous craftsmanship and thorough quality assurance in producing reliable PCBs that power our modern gadgets effectively. Each step, from the initial plating process to the final surface finishing, contributes to enhancing the PCB's electrical performance and longevity, making it a vital component in the electronics industry.

Unraveling the World of Flex Circuit Prototypes: Choosing the Right FPC Manufacturer

Introduction

Flex Printed Circuit Boards (Flex PCBs), often referred to as Flex Circuits, have become indispensable in today's electronics industry. These bendable and versatile circuit boards are a crucial component in various applications, from medical devices and aerospace systems to consumer electronics. When it comes to designing and producing Flex PCB prototypes, choosing the right FPC manufacturer is paramount. In this blog post, we will explore the world of Flex Circuit Prototypes and discuss the key considerations when selecting an FPC manufacturer.

Understanding Flex Circuit Prototypes

Flex Circuit Prototypes are specialized printed circuit boards designed to be flexible, allowing them to conform to intricate shapes or fit into compact spaces. These boards are typically made from flexible substrates like polyimide (PI) or polyester (PET) and can have single or multiple layers, depending on the complexity of the circuit. Flex circuits can be found in products ranging from smartphones and wearable devices to automotive control systems.

Why Choose Flex Circuit Prototypes?

Space Efficiency: Flex PCBs are ideal for applications with space constraints, as they can be folded or bent to fit into tight spaces, reducing the overall size of the device.

Reliability: Flex circuits offer excellent reliability due to their reduced number of interconnects, which minimizes the risk of connection failures and short circuits.

Weight Reduction: Flex circuits are lightweight, making them a preferred choice in applications where weight reduction is critical, such as aerospace and automotive industries.

Durability: These circuits are more robust and can withstand vibrations and shock, making them suitable for applications that experience harsh environments.

"As the world grows “smarter” through the adoption of smartphones, smart fridges, and entire smart houses, the carbon cost of that technology grows, too. 

In the last decade, electronic waste has become one of the fastest-growing waste streams in the world. 

According to The World Counts, the globe generates about 50 million tons of e-waste every year. That’s the equivalent of 1,000 laptops being trashed every second. 

After they’re shipped off to landfills and incinerated, the trash releases toxic chemicals including lead, cadmium, arsenic, mercury, and so much more, which can cause disastrous health effects on the populations that live near those trash sites. 

Fortunately, Franziska Kerber — a university student at ​​FH Joanneum in Graz, Austria — has dreamed up a solution that helps carve away at that behemoth problem: electronics made out of recyclable, dissolvable paper. 

On September 11, Kerber’s invention “Pape” — or Paper Electronics — earned global recognition when it was named a national winner of the 2024 James Dyson Awards. 

When she entered the scientific competition, Kerber demonstrated her invention with the creation of several small electronics made out of paper materials, including a fully-functional WiFi router and smoke detector. 

“Small electronic devices are especially prone to ending up in household waste due to unclear disposal systems and their small size, so there is significant potential to develop a more user-friendly end-of-life system,” Kerber wrote on the James Dyson Award website. 

“With this in mind, I aimed to move beyond a simple recycling solution to a circular one, ensuring long-term sustainability.” 

Kerber’s invention hinges on crafting a dissolvable and recyclable PCB board out of compressed “paper pulp.” 

A printed circuit board (PCB) is a board that can be found in nearly all modern electronic devices, like phones, tablets, and smartwatches.

But even companies that have started incorporating a “dissolution” step into the end life of their products require deconstruction to break down and recover the PCB board before it can be recycled. 

With Kerber’s PAPE products, users don’t need to take the device apart to recycle it.

“By implementing a user-friendly return option, manufacturers can efficiently dissolve all returned items, potentially reusing electronic components,” Kerber explained. 

“Rapidly advancing technology, which forms the core of many devices, becomes obsolete much faster than the structural elements, which are often made from plastics that can last thousands of years,” Kerber poses. 

PAPE, Kerber says, has a “designed end-of-life system” which anticipates obsolescence. 

“Does anyone want to use a thousand-year-old computer?” Kerber asks. “Of course not. … This ensures a sustainable and reliable system without hindering technological advancement.”"

Writing Scientist Characters

this post is mainly an excuse to post a certain list of lab supplies I've made for a friend and infodump about lab work. but feel free to use this as a little resource when writing characters who are scientists and/or lab nerds. who knows, maybe it'll be of use.

General thoughts

Many people think it's a stereotype that scientist or nerd characters talk using complex technical jargon. While that is true to an extent, there actually is some kind of lab jargon. It varies across different labs and fields, but one thing they have in common is that it seeks to simplify, not the other way around.

gelelectrophoresis becomes elpho

microbiology becomes mibi

deioninized water becomes aqua dist

biochemistry becomes BC

sodium hydroxide becomes NaOH

They will probably not call a glass of water "silicon dioxide and h2o".

...and more. feel free to get creative. If you're writing in any other language than English, you can throw in one or two anglicisms as well. Also, most scientists will never gatekeep their work, and in an opposite fashion, will not shut up about it unless you make them. And no, most chemists do not know the entire periodic table by heart, only the most relevant elements. (main groups and a few commonly used metals of the subgroups) When it comes to characters doing the lab work, keep in mind that there are a lot more people involved than the scientist themself. Most scientists are more occupied with paperwork and data analysis, it is the laboratory technicians and assistants that do most of the practical work. They often have more lab experience than the scientists themselves.

Things you can have your lab nerd character do instead of making random chemicals explode

writing a lab report (and losing their mind over excel)

degreasing the glass bevel stoppers
