PCB e-test process

August 28th, 2013 | Posted by admin in PCB production process - (Comments Off on PCB e-test process)

We have two ways of testing PCB. For small batch, it is tested by probe flying. For mass production,we will open an e-test fixture to test it. once second one piece, it is very fast. You can see how it runs from the video. Prototype Orders: Flying-Probe E-Test is always very fast and economical  for …

PCB AOI testing

August 27th, 2013 | Posted by admin in PCB production process - (1 Comments)

This is the AOI testing room. AOI equipment is very expensive. Small factories don’t have it. Many china pcb factories only have one set. So usually if you want to know whether this china pcb manufacturer is big , ask them how many AOI machine they have.

Do you know how PCB solder mask is printed in China PCB factory? This video will show you the pcb soldermask process done in the pcb workshop.

pcb washing process

August 26th, 2013 | Posted by admin in PCB production process - (1 Comments)

There are many times of washing in PCB production. This is auto washing line.There is board sensor on the line, once the pcb is coming, it start to spray water. You have to be careful if your circuit board is very thin eg.0.2mm, you cannot allow factory to use this kind of washing line. You …

PCB copper plating process

August 26th, 2013 | Posted by admin in PCB production process - (Comments Off on PCB copper plating process)

PCB plating process is very fast in pcb production. So most of time, this line is free comparing with other processes. But it is not easy to operate.The parameters such as time, power have to be adjusted for different pcb part numbers. Factory will plate one piece sample first to check quality,then they plate rest …

PCB CCL cutting process

August 25th, 2013 | Posted by admin in PCB production process - (1 Comments)

PCB cutting material process is the first step of pcb production. You could call to stop anytime before it. But the status of PCB is on cutting material, it is too late for you to call stop.Because 70% cost is the material cost.But you still could change the inner layer,drilling and so on.

Pcb lamination process

August 25th, 2013 | Posted by admin in PCB production process - (1 Comments)

Many China PCB factories don’t have the lamination equipment. Usually,they will send pcbs inner layer finished to other big factory or the lamanation factory to complete this process.It seems it is not what you like. But it is common,and you don’t need to worry about quality,because these lamination factories is very professional,they even could make …
