1.Usage
It is applicable for PCB to process drilling cover plate, and well transfer and take away the heat in the course
of drilling, meanwhile, it can prevent the drill bit from instantaneous deformation when drilling so as to keep
the precision of drill and to prevent burrs produced on the plate surface.
2.Introduction
a) aluminum surface smooth and clean. no wrinkles, dark spots appearance, ensure quality drilling
b) moderate hardness can prevent burr in the panel surface drilling at high speed;
c) improve the accuracy of the drilling position;
d) reduce drill bit wear rate,and extended drilling bit life.
3.Storage
Room temperature for 24 months, the packaging need to have moisture, sun and oxidation.
