Aluminum entry board, also known as PCB circuit board, is generally used for heat insulation board of electronic products. PCB, also known as printed circuit board. The PCB drilling aluminum entry board is generally composed of circuit and drawing, dielectric layer, hole, solder resist ink, screen printing and surface treatment. The hole is the guide through hole, which can make the circuits above two levels connect with each other. The larger through-hole is used as part plug-in. In addition, the non-conductive hole is usually used as surface mounting positioning and fixing screws during assembly. aluminum entry board is suitable for PCB drilling.
Aluminum entry board commonly used for PCB drilling aluminum entry board is 1100 , 1060 and 3003 aluminum sheet, with aluminum content of more than 99%. The main state is H18, the common thickness is 0.125-0.24mm, the coil width is about 600mm, and the sheet width is 1244 / 1245mm. PCB drilling aluminum entry board is widely used in communication, aviation, automobile, military, power, medical, industrial control, electromechanical, computer and other fields.
Advantage of Chalco aluminum PCB drilling aluminum entry board:
PCB drill quality professional development;
Chemical decontamination program line to prevent borehole pollution;
Tension straightening ensures flatness and reduces bit damage;
Special technology leads to uniform thickness and difficult hardness;
PCB drilling aluminum entry board
1. Aluminum sheet can effectively prevent the drill bit from indentation and scratch on the surface of copper clad laminate.
2. It can provide positioning and guiding function when the bit goes down to improve the positioning accuracy of drilling.
3. The PCB drilling aluminum entry board 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. PCB drilling aluminum entry board prevents burr on the surface of film copper foil when drilling at high speed.
