Printed circuit board (PCB) design software is an excellent tool for designing PCBs for electronic devices. By using PCB design software, engineers can not only solve problems related to power integrity and signal, but also modify and improve the entire circuit structure. PCB design software can be easily integrated with other associated plug-in PLM software, [...]
FPC flexible circuit boards are widely used in smart phones due to their high wiring density, light weight, thin thickness, and good flexibility. The FPC flexible circuit boards in smart phones are mainly used for the connection of parts and the motherboard, like Display modules, fingerprint modules, camera modules, antennas, vibrators, etc., with the continuous [...]
