Five factors impact to the rigid PCB drill process

How to Drilling the holes for rigid PCB? This paper will discuss Five factors impact to the rigid PCB drill process. First of all we should know some common sense to drill machine. Almost all rigid PCB drill machines were computer controlled. That’s the reason why so many PCB engineers or designers call it as […]

Prepare the stacking up for drilling rigid PCB hole

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 […]

You should know X-ray drill PCB hole process

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 […]

Electroless copper deposition process of rigid PCB

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 […]

How to image outer layer circuits of the rigid PCB board?

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 […]

Some common sense of Image the outer layers process of rigid PCB

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 […]

PCB experts introduce The right thickness of the electroplate

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 […]

Four common sense copper plating process of rigid PCB

Plating process of rigid PCB manufacturing In this paper, we will discuss the plating process. If you have visited a rigid PCB plant, you may find the plating rooms were very big. Some big rigid PCB plant has more than two plating to meet different requirements. Because some heavy copper, rigid PCBs should through the […]

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 […]

Two common sense of blind and buried vias

We have discussed the subject of blind bias and buried Vias. This paper also related to those two HDI PCB holes. But different definition introduce before, we want to introduce different topics about blind bias and buried vias. You know the technology of the blind was buried Vias are more than decades developing. Some HDI […]
