I. Tools: professional production equipment, copper foil, epoxy sheet
Two, the operation steps
1. Copper cladding sheet preparation, epoxy resin sheet is one of the most used sheet.
2. Drill holes in the copper-clad plate and make it according to the position of the specification drawing.
3. Plating is done to conduct the holes with chemical copper. This way the two sides of the circuit can be connected as one.?
4. Make the lines on the copper plate. It is also called graphic transfer, which is to remove the excess copper and make copper wires on the copper surface according to the designed line direction.
5. Then make solder protection. Also called solder resist, it has the function of protecting the lines and plates.
6. Characters, also called text, the role of the PCB assembly components identification. Remove the desktop computer can see such a board with text. It is the PCB
7. After making it, you need to define the dimensions. Now comes the cutting part, also called molding.
8. PCB board is cut into small pieces. It is necessary to test his electrical performance. Whether it can conduct. Energized whether it is effective.
9. Through the test of the board, in order to make it beautiful, but also to carry out an appearance check to see if there are defects.
10. Finished products are packaged, boxed and shipped.
11. To here can not be marketed. Because there are assembly plants for component welding, shell assembly. Finally to enter the market.
