Molding, in industrial design, refers to the tool group that forms product design, including mechanical equipment and molds. What we usually call mold opening refers to the mold used to punch the plate when the product is making the shape, and some factories refer to the test frame. So, do you need to open the mold for PCB circuit board proofing?

By understanding the definition of mold opening, we can understand whether or not to open mold for PCB circuit board proofing. PCB is just a board with fixed specifications and parameters. It is the core component inside the electronic product, not the product shape. The PCB proofing product is only used for testing and debugging. In this process, if there is a problem with the proofing drawing, which leads to an error in the PCB board, it can be improved by repeatedly modifying the data until a good effect appears. In terms of testing, you can choose the flying probe test, which will reduce a lot of risks. Therefore, the circuit board for PCB proofing does not need to be opened, and it can be made directly by CNC. Flexible circuit board

Mold opening is usually used for batch processing of product appearance, with large shipments, fast speed and low price; once the appearance structure drawing is fixed, it cannot be modified. If it needs to be modified, the mold must be reopened, which will cause the original mold to be scrapped, waste product development time, and increase production costs. When opening the mold, you should also pay attention to the positioning of your own products. Some products do not accept mold punching, so there is no need to open the mold.
