Aluminum drilling entry

 Aluminum drilling entry, also known as PCB circuit boards, are generally used for insulation boards for electronic products. PCB, also known as printed circuit board, also known as printed circuit board, printed circuit board, referred to as printed board, is made of insulating board as a substrate, cut into a certain size, with at least one conductive pattern attached, and is covered with holes ( Such as component holes, fastening holes, metallized holes, etc., used to replace the chassis of the electronic components of the prior device, and to achieve interconnection between electronic components. Since this board is made by electronic printing, it is called a "printing" circuit board.

The aluminum alloy commonly used for aluminum drilling entry is 1100/1060/3003, the state is H18, 3003/H19/H18, the common thickness is 0.125-0.24mm, the sheet width is 1244/1245mm, the length is 940/1041/1092mm, the coil width It is around 600.

The aluminum gasket has excellent heat conduction function, which can quickly dissipate the heat generated by the friction when the drill bit is drilled at a high speed, effectively prevent the drill bit from overheating, thereby improving the life of the drill bit and the better condition of the hole wall.
