Simple Introduce of Through-hole Etch-back Technology of Rigid-flex PCB

Why need Through-hole etch-back? As we know there are more and more smart device, and more smaller. In other hand, require high end PCB board. And more of the time those devices require flex PCB or rigid-flex PCB. Some of China flex-rigid PCB factories have developed through-hole etch-back technology to meet high end requirement. Top […]
