The production method of the backlit FPC black hole plate surface indentation device is described.

　　FPC black hole wireIt is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film. In the production process, it has the characteristics of high wiring density, light weight, thin thickness and good bending property. In order to prevent too many open and short circuits from causing too low yield or reduce the problems of scrapping and replenishing FPC black-hole wire boards caused by rough process problems such as drilling, calendering and cutting, and to evaluate how to select materials to achieve the best results for customers, prenatal pretreatment is especially important. The thick thickness of the copper plate used on the traditional FPC can not effectively conduct information, but also increase the volume of the circuit board, and the traditional production process of FPC will produce indentation on the board, but can not effectively deal with the indentation, seriously affecting the appearance of the board. To this end, we designed a new type of backlit FPC black hole plate surface indentation device, which solved the problem of the inconvenience of the traditional backlit FPC black hole plate surface indentation device.

1. With traditional backlightFPC Black Orifice PlateCompared with the surface indentation device, the improved backlight FPC black orifice plate surface indentation device is equipped with a high-temperature spray gun and a pressure plate in the calendering device. The high-temperature spray gun heats the copper plate, so that the copper plate passes through the rolling roller, and the rolling roller rolls the copper plate. When the copper plate is below the pressure plate, the pressure plate stamps the copper plate, making the copper plate into a thin sheet, the spring in the carrier plate acts as a buffer against the impact force generated by the stamping.

2. Compared with the traditional backlight FPC black hole plate surface indentation device, the improved backlight FPC black hole plate surface indentation device is equipped with a drill, a cutter and a sprayer in the cutting equipment. The cutter cuts the copper plate, the driller drills the cut copper plate, and when the copper plate after drilling through the hole passes under the sprayer, the surface of the copper plate is wetted, thus removing the indentation on the surface of the copper plate.
