The commonly used aluminum alloy of aluminum gasket is 1100 coil, 1060 coil and 3003 plate, with aluminum content of more than 99%. The state is mainly h18, with common thickness of 0.125-0.24mm, coil width of about 600mm and sheet width of 1244 / 1245mm. Aluminum gasket is widely used in communication, aviation, automobile, military, electric power, medical treatment, industrial control, electromechanical, computer and other fields.
Using aluminum sheet for PCB drilling has the following advantages:
1. The aluminum sheet can effectively prevent the drill nozzle from producing indentation and scratch on the surface of CCL during processing.
2. It can provide positioning and guiding function in the process of bit down, and improve the positioning accuracy of drilling.
3. The aluminum sheet has excellent heat conduction function, which can quickly dissipate the heat generated by friction when the bit is running at high speed, effectively prevent the bit from overheating, so as to improve the life of the bit and better hole wall condition.
4. The aluminum gasket prevents burr on the surface of copper foil when drilling at high speed.
