05-312020Suggestions for multilayer PCB designMulti-layer PCB design suggestions and examples (4, 6, 8, 10, and 12-layer PCB boards) illustrate the PCB design requirements: A. The surface is a complete ground plane (shield); B. There are no adjacent parallel wiring layers; C . All signal layers are as close as possible to the ground plane; D. The key signals are adjacent to the ground layer and do not cross the partition.

05-242020The difference between Rigid PCB and Flex PCBBoth rigid circuit boards and flexible circuit boards have similarities and differences before. For the flexible circuit board, the application of the rigid circuit board is more extensive. Because the rigid circuit board appeared earlier, most of the design elements of the rigid circuit board have been applied to the design of the flexible circuit board. What is the difference between flexible circuit boards?
