Before the PCB drilling process, it is necessary to regularly stack the PCB board, the wooden backing board and the aluminum sheet through the PIN needle and the surrounding tape. The process requirement of the PIN height is to exceed the PCB board plane ±0.5mm. However, in the actual production process, due to the difference in the thickness of the PCB board, and the difference between 2 and 3 PCB boards included in each stack, the thickness of the PIN pin passing through the PCB board is different. The changeover production of PCB boards with different thicknesses results in the change of the depth of the PIN needle passing through the PCB board. Therefore, during the changeover production, it is necessary to manually adjust the adjustment screw of the cylinder stroke that drives the PIN needle. It takes about 30 minutes to adjust the adjusting screw of the cylinder stroke each time to meet the qualified requirements, and it takes about 30 minutes to process several products and conduct tests.
