What is the light blue oil component used for brush circuit boards
The gravure plate is photographed with a good background, and the layout should be the same size as the PCB. PCB photolithography process is roughly the same as the ordinary camera, can be divided into: slice cutting - exposure - development - repair - washing - dry - revised version. Perform the camera to check the correctness of the base map,
The bottom layer is drawn by the designer, while the printed circuit board manufacturer to ensure the quality of the PCB processing should check these basemets, do not meet the requirements and need to be redrawn.
Generally through the membrane, graphics transfer, chemical etching, through-hole and copper processing, flux and solder processing technology.
Printed circuit board manufacturing process is developing rapidly, and different types of PCBs require different technologies, but the basic method is the same.
