Three key technology of etch rigid PCB outer layer

Most green hands rigid PCB designers don’t know how to etch outer layer circuit. That’s the reason why so many accidents during an etch circuit step. Of course, this issue related to operator’s experience. But many times depend rigid PCB designer’s skill, the etch circuit design process. So 4MCPCB have to introduce the detail technology […]
