Best selling mill finish aluminum plate for pcb

Aluminum drill entry sheet, also known as aluminum sheet for PCB, mill finish aluminum plate for pcb, are commonly used for insulation plates for printed circuit board. The aluminum alloy commonly used for drill entry aluminum are 1100 aluminum plate and 1060 aluminum plate, the temper is H18, the common thickness is 0.125-0.24mm, the width is 1244/1245mm, the length is 940/1041/1092mm.

mill finish aluminum plate

What are the advantages of aluminum brilling entry sheet with 1100 aluminum alloy and 1060 aluminum alloy? First, the 1100 aluminum plate and the 1060 aluminum plate effectively prevent the drill bit from being indented and scratched on the surface of the copper clad plate during the processing. It can provide positioning and guiding function during the downward process of the drill bit to improve the positioning accuracy of the drilling. Secondly, 1100 aluminum plate and 1060 aluminum plate for pcb have excellent heat conduction function, which can quickly dissipate the heat generated by friction when the bit is drilled at high speed, effectively prevent the bit from overheating, thereby improving the life of the bit and better wall condition, which can effectively prevent the burr generated on the surface of the film copper foil when drilling at high speed.

The surface requirements of the mill finish aluminum plate for pcb are: the surface of the aluminum plate should be clean, and cracks and oxidized impurities are not allowed, defects such as depression, scratches, and roll indentations are not allowed on the surface of the aluminum plate for pcb.
