What problems do you need to pay attention to in the appearance method of PCB processing? Here give you some points to let you understand some problems about PCB processing more
comprehensively, understand these problems clearly believe that you will get more knowledge in the field of processing:
One: Adjust the mold as much as possible with manual, rather than maneuvering.
Two: Start the press, a comprehensive check including the clutch, brake, slider and other parts are normal, the operating mechanism is reliable, there is no continuous impact phenomenon.
Three: To prepare several sets of pressure plate and T-head pressure plate screws, in order to use corresponding with the mold. The front end of the platen should not touch the straight wall of the lower die. Emery cloth should be padded between each contact surface, and screws must be tightened.
Four: In order to improve the blanking performance of the substrate, the paper substrate should be heated. Its temperature is better at 70 ~ 90℃.
Five: Select the punching machine (including type, tonnage) according to the punching force calculated by the die design, the size of the die, the closing height, etc.
Six: The pad iron under the die, generally 2 pieces, must be ground out at the same time on the grinder to ensure that the mold is installed parallel and vertical. Intercalation of the cushion iron is not hindered by blanking while being as close to the center of the mold as possible.
Seven: Mold installation should pay great attention to the screws and nuts on the lower die do not touch the upper die (the upper die falls and closes)
