Abstract

The invention relates to a routing process for precisely controlling the appearance of a substrate. A to-be-routed whole substrate is provided; the whole substrate comprises at least two forming units; and the routing process comprises the following steps of (S1) measuring the expansion and shrinkage conditions of the overall dimension of the substrate; (S2) routing and positioning: positioning the substrate; (S3) parameter setting: inputting positioning data, inputting data of the substrate and setting machining parameters; (S4) coarse routing slotting: forming inner slots in the inner sidesof the forming units through a coarse routing tool; (S5) fine routing cutting: cutting the inner slots and the peripheries of the forming units through a fine routing tool; (S6) first part confirming:confirming the dimension of the cut first forming unit, confirming that the dimension meets the requirements and entering massive production; and (S7) carrying out QA sampling inspection in the production process. According to the routing process, the problem of scrappage due to the fact that the dimension does not meet the requirements is solved, the appearance quality is improved, the scrap rate is reduced and the requirements of customers on the dimension are met at low cost input and high quality output.

Description

technical field [0001] The invention relates to the field of circuit board processing, in particular to a gong board process for precisely controlling the appearance of a substrate. Background technique [0002] With the development of electronic technology, PCB boards have replaced the connection methods of traditional electronic components and are widely used in electronic products. [0003] At present, in the PCB board processing industry, in order to facilitate large-scale production and improve production efficiency, it is often necessary to first manufacture a whole PCB board containing multiple PCB boards (also known as single PCS boards or printed circuit boards) ( Also known as a whole printed circuit board); then, by processing the entire PCB board to form multiple PCB single boards and / or form a PCB connection board (also known as a printed circuit connection board ). [0004] The methods for processing the shape of the entire PCB mainly include V-CUT, beer boar...
