Abstract

The invention provides slot processing technology for a printed circuit board, which comprises the following steps of: selecting a main drill layer to be exported; filtering slots in the printed circuit board; creating a primary data list in which exported cutter number corresponds to the slot number; and circulating the data list, reducing the original aperture of the printed circuit board one by one, and correspondingly acquiring a new drill, wherein the new drill corresponds to the arrangement order of a plurality of cutters. The slot processing technology for the printed circuit board can reduce complicated procedures of manual operation, ensure the safety of the original drill, effectively avoid drill breakage, and greatly improve the manufacturing yield of the printed circuit board.

Description

technical field

[0001] The present invention relates to printed circuit board (Printed Circuit Board, PCB) technology, in particular, relates to a slot hole processing technology of printed circuit board. Background technique

[0002] In the traditional printed circuit board processing technology, the slot hole processing technology is usually formed by using cutting tools in the printed circuit board material to be processed to form long holes, short holes, long slots, short slots, etc. required by various designs, in order to achieve Subsequent production of various processes for the entire printed circuit board. Since different slots need to be realized with different processing tools, among them, according to the different shape requirements of the formed slots, the processing tools used also include slot cutters, gong cutters, boring cutters, milling cutters, drills, etc., and are different The processing trajectory paths corresponding to different processing tools are...
