PCB design technology

PCB Boardssfyh
The key to PCB EMC design is to minimize the reflow area and let the reflow path flow in the direction of the design. The most common return current problems come from cracks in the reference plane, changing the reference plane layer, and the signal flowing through the connector. Jumper capacitors or decoupling capacitors may solve some problems, but the overall impedance of capacitors, vias, pads, and wiring must be considered. This article will introduce EMC’s PCB design technology from three aspects: PCB layering strategy, layout skills and wiring rules. PCB layering strategy The thickness, via process and the number…
