Copper application points for PCB design
Copper coating on PCB board, if the grounding problem is handled well, is certainly "more advantages than disadvantages", it can reduce the signal line backflow area, reduce the signal external electromagnetic interference
Shielding methods in high speed PCB design
Shielding method in high frequency PCB design: the twisted pair in data twisted pair can resist external interference and cross-talk between pairs through its own twisting at low frequency, but at high frequency, only twisting and merging can not achieve
Common problems in PCB design
What is the cause of PCB board broken line: 1, film process: 2, exposure process: 3, development process: 4, etching process: 5, electroplating problem: 6, improper operation
Electromagnetic compatibility in PCB design
When the field strength of electromagnetic field exceeds a certain limit and the operation time is long enough, it may endanger human health. It can also interfere with other electronic devices and communications. All of these need to be protected.
