摘要: Abstract:With the rapid increase in the popularity of domestic surface mounters, as the core equipment for high precision and high speed in modern electronic assembly, the electromagnetic compatibility issues of surface mounters are becoming increasingly complex. Shielding wires play a crucial role in suppressing electromagnetic interference, ensuring the integrity of signal transmission, and enhancing the stability of equipment operation. Some occasional and uncertain movements of the surface mounter are mainly caused by improper wiring of the shielding wires or excessively long grounding wires.
