Abstract

The present invention discloses a new depth-drilling method and PCB finished product drilled by the method. The method includes steps of designing a stage control loop in a POWER layer inside a PCB; using a drill bit to drill down to the POWER layer and then calculating a configured depth to be drilled; or drilling testing holes Z1, Z2 and Z3 on edges of regions to be drilled of a top surface, an upper target layer and a lower target layer of a PCB under production; next adding G87, G88 and G89 functional commands to a control software for the stage so that the stage can detect depth values of Z1 and Z2; determining a depth value to be further drilled in accordance with the positions of Z1 and Z2; and lastly enabling the stage to make a drilling with a depth value (Z2 + Z3)/2 plus one drill point as a compensation value. The non-through-hole accuracy of the PCB finished product obtained by the method can be controlled under ± 1.5 mil.
