In today's trend towards miniaturization, high performance, and high mobility in electronic devices, every cubic millimeter of internal space is precious.
During testing, the working status of the circuit board needs to be monitored to ensure that there are no resets, crashes, or abnormal outputs.
In the context of modern electronic devices' continuous pursuit of miniaturization, lightweighting, and high performance, high-power-density circuit boards have become a key supporting technology.
In modern lighting systems, the light source is no longer a simple bulb, but a highly integrated, intelligent, and controllable optoelectronic unit.
Power board and circuit board need to suppress electromagnetic interference (EMI) through layout optimization, shielding design and filtering technology.
When a signal passes through a via with discontinuous impedance, part of the energy will be reflected back to the source end and superimposed with the incident signal to form interference.
