Practical Guide to Copper Pouring in High-Density PCBs: Design Philosophy for Controlling Residual Copper Rate

Copper pouring is an important aspect of Jialichuang’s high-density PCB design. The significance of copper pouring lies in reducing ground line impedance, enhancing anti-interference capability; lowering voltage drop, improving power efficiency; and connecting with the ground line to reduce loop area. It is advisable to use cross pads on copper pouring surfaces We know that … Read more

PCB Design Checklist: Routing

Route according to the 50-ohm impedance line width, try to route from the center of the pad, keeping the lines straight and preferably on the top layer. When a bend is necessary, make it at a 45-degree angle or as an arc, preferably bending near capacitors or resistors. If routing meets the matching requirements of … Read more
