1100/3003/3105 pcb aluminium entry sheet

The entrance plate of aluminum drill bit refers to the aluminum plate used for PCB drilling. PCB aluminium entry sheet has excellent thermal characteristics, which can cool the drill bit and reduce resin accumulation.It is made of drawn hard aluminum to maximize machinability while maintaining high thermal conductivity and reducing burrs. Excellent flatness and controlled surface roughness provide reliable bit alignment and reduce drift and bit breakage. Protect the substrate below from foot marks and scratches.

Application:
1. Aluminum drilling meter can protect circuit board from scratch and imprint marks.
2. Aluminum plate can increase the accuracy of drilling position. It is helpful for drilling to ensure that the drilling function is not deviated.
3. The service life of the bit is greatly prolonged. Its special alloy composition will keep the bit clean and cool. What's more, it's really an excellent thermal conductor, so it helps to prevent overheating of the drill bit and prevent oxidation at the top.
