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
