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.
In the design of power boards, the crosstalk between digital and analog signals has always been a key factor affecting circuit performance.
In LED lighting systems, the lifespan and light output stability of the light source are not solely determined by the LED chip itself, but also by the thermal management capabilities of its operating environment.
