Phenomena such as deformation occurred with slot, lead to not the quality and dimensional accuracy that meet short slot in existing PCB printed wiring board
Demand.
As slot special-shaped in PCB printed wire is more and more, during carrying out processing profiled hole, for the angle V and the angle R
There is part PP in position, and cutting is clean completely, when main cause is at present using slot knife and drill bit present operation, relies primarily on
Apex point face is cut, because side leads to not cut completely completely without cutting force.
The material increasingly diversification used with PCB printed wire, for iron teflon plate and aluminum substrate, carry out at
Cause during type cutting (transverse cuts) because of current use for multiple cut, because the characteristic iron teflon plate of raw material is than soft
Soft, aluminum substrate is harder and bits are easy to glue above multiple cutter, the bad normal exclusion of aluminium skimmings.
