There will be some tests to be done before the circuit board is formed. The staff of our circuit board factory will test the formed circuit board, so what are the precautions before forming? Let the editor reveal the secret for you.
Precautions for circuit board factory molding
Generally, our circuit board factory will test milling before forming. Trial milling refers to milling only one board (try to choose scrap board for trial milling), and check whether the quality meets the requirements, and only if it meets the requirements Formally mass-produced milling. In order to prevent missing milling or misalignment, check the board quality for any problems after each processing.
The backing board is usually a paper laminated board, which is costly. Generally, the backing plate used for milling shape uses the backing plate that has been drilled and used to save costs; there are also circuit board manufacturers that use acid aldehyde resin board as the backing plate, and the plate is used by PCB manufacturers with few product types and large batches.
So what are the production precautions that we need to pay attention to? Shenzhen PCB factories are becoming more concentrated, and the PCB factory industry is developing rapidly. Strict quality control is what our production staff need to do.
Precautions for circuit board factory molding
(1) The coordinate system includes the platform coordinate system and the program coordinate system. The origin of the machine coordinate system is the center of the machine positioning hole; the origin of the program coordinate system can be set arbitrarily, but the milling graphics must be within the working range of the spindle, and the program origin must be consistent with the origin of the pin air hole program, This is to unify the two origins when the circuit board factory makes the milling profile program.
(2) Choose S reasonable pins to ensure the dimensional accuracy of the milling plate.
(3) If the board warps severely, it must be leveled before milling.
