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
DIYer: Smiling Duck Production Time: Half a Day Difficulty Level: ★★☆☆☆ GEEK Index: ★★★☆☆ Are you still using a universal board for repairs? Are you struggling to create the circuit and layout you want with a universal board? For many electronic enthusiasts today, a universal board can no longer meet the production needs, but having … 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
1. Faults Caused by Capacitor Damage Capacitor damage is the most common fault in electronic devices, particularly with electrolytic capacitors. Signs of capacitor damage include: reduced capacitance; complete loss of capacitance; leakage; short circuit. Different capacitors serve various roles in a circuit, leading to distinct fault characteristics. In industrial control circuit boards, digital circuits dominate, … 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
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
Search WeChat Technical Training Comparison of Breadboards and Universal Boards Welding Methods for Universal Boards For the layout of components on the universal board, most people are accustomed to “following the clues,” centering around key components like chips and inserting other components wherever possible. This method reflects order in the chaos of soldering, and is … Read more
