We don't want to discuss judge Printed Circuit Boards manufacturers factors.
Because every electronics company has each own judgement.
But we will be sharing all Printed Circuit Boards making (PCB making) detail process manufacturer.
During to PCB manufacturing is a very very complex process.
One article can't include all steps of the PCB manufacturing process.
So Jim wants to introduce Printed Circuit Boards manufacturing process step by step.
Today we are going to discuss PHOTO-RESIST board.
First is the definition of the PHOTO-RESIST.
Most of Printed Circuit Boards manufacturers don't introduce this definition.
Not only the short experience of PC board manufacture.
But also a professional skill of your PCB supplies.
In fact PHOTO-RESIST board just the material of PCB made.
PHOTO-RESIST board is a piece of glass reinforce plastic.
Second is the reason why chooses PHOTO-RESIST board can make PCB boards.
This is very very professional PCB question.
Even some of the experience PCB assembly guys also don't know the real reason.
If you look the PHOTO-RESIST board carefully.
You may notice most Printed Circuit Boards manufacturers use PHOTO-RESIST board not just one copper.
One of the sides is copper clad and this copper has a photosensitive coating.
This means it can easily be imaged.
The third issue is how PHOTO-RESIST board made from Printed Circuit Boards.
To be honest this related to all steps of PCBs making process.
But most relevant to PHOTO-RESIST boards is the film.
This is design by the PCB design apartment.
After the produce worker use PCB designs data to image wires.
When the plastic film is peeled back this sensitive coating is revealed.
After processing this will be the PCB.
And the end of PCBs process is express PCB.
Different customers choose different transport.
May the ship process very long time.
So this requires PCB have good performance.
This also related to PHOTO-RESIST boards.
That's why so many Printed Circuit Boards manufacturers use this material.
