Why we should discuss the stack up for drilling rigid PCB hole? One reason is that most rigid PCB manufacturers will drill several panel raw materials at one time. So this time prepare the stack up of raw PCB material means very important. Then, some green hands workers stack up many, many panels in derailing […]

Why we discuss x-ray drill PCB hole process? The x-ray drill PCB hole method doesn’t use so widely, and there were many guys don’t this drill PCB hole method. Emma wants to share more about all detail technology about PCB manufacturer. We will from three parts to discuss x-ray dill affect rigid PCBs. Two functions […]
Not all kinds of PCB board need through the electroless copper deposition process. 4MCPCB experts told Emma that it’s may the most easy understand process in all rigid PCB manufacturing. Why should we chemical deposit copper on hole wall It’s a common sense that all PCB thickness must be electroplated. If you have know the […]
We have introduced some common sense of image circuits. If you just a new guy for PCB, please read previous article firstly. It can help you understand the image outer layer circuits technology more easy. Or you can contact 4MCPCB experts to ask some related questions. How to align the phototool and the panel? This […]
Image the outer layers process of rigid PCB should be in clean room If you visit a professional rigid PCB factory, you must find many processes in clean room, likely image the outer layer process. But why we should take this step to clean room, or the risk of image outer layer circuit process? We […]
Do you know the right thickness of the electroplate First factor is the thickness copper of the hole walls. You know different layer circuit is connected by the hole wall copper. Rich experience rigid PCB designers summarized some tips below. The better conductivity through the holes, the better electronic performance of rigid PCB has. Then […]
