Abstract
The invention belongs to a superhard PCB (Printed Circuit Board) processing method capable of effectively prolonging the service life of a cutting tool. The processing method is characterized by adopting the following steps that a, a HITACHI mechanical digital controlled drill (8) is selected; b, a diamond coating drill bit (2) is mounted on a clamp of a main shaft (1) of the HITACHI mechanical digital controlled drill; c, a superhard PCB is placed on a table board (5) of the HITACHI mechanical digital controlled drill, and a water soluble aluminium cover plate (3) is fixed to the upper face of a circuit board I (4); and d, during drilling, the linear speed of the diamond coating drill bit (2) does not exceed 400m/min, and the feed amount is between 25 micrometers and 100 micrometers. The water soluble aluminium cover plate (3) is formed by bonding an HLE efficient thermosensitive layer (3-1) on an aluminium layer (3-2). According to the superhard PCB processing method capable of effectively prolonging the service life of a cutting tool, the service life of the drill bit is effectively prolonged when the superhard PCB is processed, and the drilling quality is improved.
