3003 H18 H19 aluminium entry board burr free

With the rapid development of electronic technology, printed circuit boards are widely used in various fields, and almost all electronic devices contain corresponding printed circuit boards. In order to ensure the normal operation of electronic equipment, reduce mutual electromagnetic interference, and reduce the adverse effects of electromagnetic pollution on humans and the ecological environment, the electromagnetic compatibility design and quality cannot be ignored.


 
3003 H18 H19 aluminium entry board can meet the requirements of aluminum gasket alloy composition, generally used thickness is 0.125-0.24mm, width is 1244/1245mm, length is 940/1041/1092mm, widely used in communications, aviation, Automobile, military, electric power, medical, industrial control, electromechanical, computer and other fields.
 
3003 H18 H19 aluminium entry board advantages of aluminum gasket:
1. The aluminum sheet effectively prevents the drill tip from indentation and scratches on the surface of the copper clad laminate during processing.
2. It can provide positioning and guiding function during the downward process of the drill bit to improve the positioning accuracy of the drilling.
3. The aluminum sheet has an excellent thermal conductivity function, which can quickly dissipate the heat generated by friction when the drill bit is drilled at high speed, effectively prevent the bit from overheating, thereby improving the life of the bit and better hole wall condition.
4. This material prevents burrs from being produced on the surface of the film copper foil board during high-speed drilling.
