Drilling method and drilling machine

Abstract

The invention discloses a drilling method and a drilling machine. The drilling method is applied to the drilling machine, and includes acquiring first height difference between first metal layers and second metal layers of deep drilling control testing modules; acquiring second height difference between the first metal layers and third metal layers of the deep drilling control testing modules; performing deep drilling control machining on to-be-machined holes according to the first height difference and the second height difference when deep drilling control machining is about to be performed on the to-be-machined holes in printed circuit boards. The first metal layers and the second metal layers respectively correspond to first circuit layers and second circuit layers of the printed circuit boards, the first circuit layers are surface-layer circuits of the printed circuit boards, and the second circuit layers are circuit layers which are required to be drilled out when the printed circuit boards are drilled. The third metal layers correspond to third circuit layers of the printed circuit boards, and the third circuit layers are circuit layers which are not allowed to be drilled out when the printed circuit boards are drilled. The to-be-machined holes in the printed circuit boards correspond to the deep drilling control testing modules.

Description

technical field [0001] The invention relates to the field of printed circuit boards, in particular to a drilling method and a drilling machine. Background technique [0002] At present, electronic products have become an indispensable main role in people's lives. As people's demand for electronic products increases day by day, higher requirements are put forward for printed circuit boards (Printed Circuit Board, PCB), one of the important components of electronic products. [0003] In order to reduce the loss or interference of the signal of the printed circuit board, in the production process of the printed circuit board, especially some communication boards using high-frequency technology, such as some servers or the carrier base boards of communication base stations, often use controlled depth drilling technology to process Holes in printed circuit boards that require controlled drilling depth. Please refer to figure 1 , figure 1 It is a schematic diagram of the proce...
