Describes how it works when using only copper PCBs from a printed circuit board as a heat sink. First understand the circuit requirements.
8 Q&A in PCB Circuit Layout Design
The mechanical design includes selecting the appropriate board size, board thickness, board stacking, inner copper barrel, aspect ratio, and the like.
Most of the design performance of multi-substrate is similar to that of single-substrate or dual-substrate, that is, care should be taken not to fill too many circuits with too small space, resulting in unrealistic tolerances, high inner layer capacity, and possibly even endangering product quality. Security. Therefore, the performance specification should take into account the complete evaluation of thermal shock, insulation resistance, solder resistance, etc. of the inner-layer circuit. The following describes the important factors that should be considered in multi-substrate design.
The application of differential signal in high-speed circuit design is more and more extensive. The most critical signal in the circuit always uses differential structure design. What other way is it so popular? How can we ensure good performance in PCB design? With these two questions, we will discuss the next section. What is a differential signal? In layman's terms, the driver sends two equal-valued, inverted signals. The receiver determines whether the logic state is "0" or "1" by comparing the difference between these two voltages. The pair of traces carrying the differential signal is called differential trace.
