When it comes to circuit boards, many people should be familiar with them, as they are ubiquitous in our lives, from small devices like Bluetooth headsets, electronic watches, and calculators to larger systems like computers, communication devices, and military/aerospace systems. Wherever integrated circuits are needed, they rely on PCB to carry electronic components. Before PCB … Read more
In the process of circuit design, application engineers often overlook PCB layout. The common issues encountered are that the circuit schematic is correct, but it does not function properly or only operates at low performance… Have you faced this too? Today, I share an article by TI application engineer Timothy Claycomb on how to properly … Read more
PCB Manufacturing Process The manufacturing of PCBs is very complex. Taking a four-layer printed circuit board as an example, the main steps include PCB layout, core board manufacturing, inner layer PCB layout transfer, core board drilling and inspection, lamination, drilling, copper plating of the hole walls, outer layer PCB layout transfer, and outer layer PCB … Read more
PCB grounding is a concern for PCB layout engineers, such as how to effectively plan a grounding system on the board, whether to wire analog, digital, and power grounds separately or together at a single point, and how to eliminate ground loops on the circuit board. Today, we will mainly discuss PCB grounding design, PCB … Read more
The names of circuit boards include: circuit board, PCB, aluminum substrate, high-frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin printed circuit board, and printed (copper etching technology) circuit board, etc. Circuit boards miniaturize and visualize circuits, playing an important role in the mass production of fixed circuits and optimizing electrical layouts. … Read more
Recycling Market Value The price of waste circuit boards mainly depends on the content of precious metals inside. For example, the price of a ton of waste circuit boards from TV circuit boards is around 30,000 to 40,000 yuan. A ton of computer boards typically contains about: 300-500g of gold, 130kg of copper, 10kg of … Read more

How are circuit boards made? The production process of PCB boards can be roughly divided into: Printed circuit board—inner layer circuitry—lamination—drilling—plating through holes (first copper)—outer layer circuitry (second copper)—solder mask green paint—text printing—contact processing—shaping and cutting—final inspection and packaging. So there are many devices involved; what equipment does PCB need? Generally, the production of PCB … Read more
Electromagnetic compatibility refers to the ability of a device or system to function properly in its electromagnetic environment without causing unacceptable electromagnetic interference to anything in that environment. The purpose of electromagnetic compatibility design is to ensure that electronic devices can suppress various external interferences, allowing them to operate normally in specific electromagnetic environments, while … Read more
When hardware engineers first encounter multi-layer PCBs, it can be quite overwhelming. With sometimes ten or more layers, the layout resembles a spider web. Are you still struggling? Today, I’ve created several internal structure diagrams of multi-layer PCBs, using 3D graphics to display various stacking structures of PCB internal architecture, helping you to see clearly. … Read more
