Glass epoxy double-sided PCB drilling
From Japan
On 2013-05-29 10:09:51
Traditionally I used ordinary steel drills, but in the case of glass epoxy it is so hard that the tip wears out quickly, and when I pierce the hole I got a lot of Paris on the exit side but a beautiful hole began to empty. I do not yet know how long the life span is, but I felt wear out conspicuously in the case of conventional steel for two empty, but there is no such thing.
