Method for manufacturing universal backing plate of PCB solder mask plug hole

Abstract

The invention discloses a method for manufacturing a universal backing plate of a PCB solder mask plug hole, and the method comprises the following steps: taking a to-be-processed substrate, drillinga positioning hole in the to-be-processed substrate, and fixing the to-be-processed substrate on a gong table by using a fixing pin; setting the specification of first milling grooves according to first milling path data, wherein the first milling grooves are arranged at equal intervals along the long edge and the wide edge of the substrate; adjusting the depth of a first milling cutter, and performing the sinking milling of the substrate to obtain the first milling grooves, wherein the first milling grooves are arranged in a grid shape; and setting the specification of second milling groovesaccording to the second milling process data, wherein the specification of the second milling grooves are smaller than the specification of the first milling grooves; adjusting the depth of a second milling cutter, and milling through the substrate in the first milling grooves according to the specification of the second milling grooves. The method has the advantages that the manufacturing steps are simple, the manufactured base plate is high in universality, the manufacturing cost and the storage management cost of the hole plugging base plate are greatly reduced, and production, operation and use are facilitated.

Description

technical field

[0001] The invention relates to the field of printed circuit boards, in particular to a method for manufacturing a PCB solder-resisting plug hole universal backing plate. Background technique

[0002] At present, the solder resist plugging process in the industry usually uses a special plug hole backing plate for each part number, because each part number requires special tools, including the production of drill tape data, the production of drill backing plates for drilling rigs, plate preparation, backing plate storage and use management , its production and use costs are higher, and there are problems such as that the backing plate of the plug hole is easy to be confused and lost, and it is difficult to find it. According to the production cost of drill belt data for each backing board is 100 yuan, the labor cost of backing board production is 300 yuan, the cost of backing board material is 50 yuan, and the cost of each backing board is 450 yuan in total.
