A kind of manufacturing method of pcb solder resist plug hole universal backing plate

Abstract

The invention discloses a method for making a universal backing plate for PCB solder-resisting plug holes, which comprises the following steps: taking a substrate to be processed, drilling positioning holes on the substrate and fixing it on the platform with fixing pins; according to the first process data Set the specifications of the first gong groove, the first gong groove is arranged at equal intervals along the long side and the wide side of the substrate, adjust the depth of the first gong knife and sink the gong on the substrate to obtain the first gong groove, so The first gong grooves are arranged in grid form; the specifications of the second gong grooves are set according to the second gong stroke data, and the specifications of the second gong grooves are smaller than the specifications of the first gong grooves. After adjusting the second gong knife depth, the The substrate is passed through the first groove according to the specification of the second groove. The manufacturing method of the PCB solder-resisting plug hole universal backing plate of the present invention has the advantages of simple manufacturing steps, strong versatility of the manufactured backing plate, greatly reducing the production cost and storage management cost of the plug hole backing plate, and being convenient for production operation and use.

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.

[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 relatively high, and there are problems such as the plug hole backing plate is easy to be confused and lost, and it is difficult to find it

According to the production cost of the drilling belt data of 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. If the number of backing boards is remade every day, it is counted as 3 , the monthly production cost of backing boards is 3 x 450 yuan x 30 days = 40,500 yuan, which greatly increases the production cost of the enterprise
