Advantages of 3015 h18 H19 aluminum foil for PCB entry sheet:
1. 3015 H18 H19 aluminium foil for PCB entry sheet can effectively prevent the drill bit from indentation and scratch on the surface of copper clad laminate.
2. 3015 h18 H19 aluminum foil for PCB entry sheet can provide positioning and guiding function when the bit goes down to improve the positioning accuracy of drilling.
3. The 3015 h18 H19 aluminum foil for PCB entry 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, thus improving the life of the bit and better hole wall condition.
4. This material prevents burr on the surface of film copper foil when drilling at high speed.
