Abstract

The invention discloses a film-pasted PCB routing technology without positioning holes. The technology comprises the following steps: S1, checking mechanical elements; s2, positioning and fixing the PCB; s3, first depth control milling of the coarse-tooth milling cutter: S31, setting parameters of the milling cutter; s4, PCB film pasting: S41, taking down the PCB subjected to the depth control gong; s5, performing second depth control milling by the coarse-tooth milling cutter; s6, fine trimming is conducted through a fine-tooth milling cutter; S61, parameters of the milling cutter are set; s62, the edge of the PCB is trimmed through a fine-tooth milling cutter, so that the edge of the PCB is smoother, and the rough edge of the PCB formed by rough milling is polished; s7, dust treatment; s8, performing large-scale production; and S9, casual inspection of finished products. According to the positioning-hole-free film-pasted PCB routing technology, through cooperation of the first depth control gong of the coarse-tooth gong cutter, the green film and the second depth control gong of the coarse-tooth gong cutter, under the condition that no positioning hole exists in a unit, the green film is used for promoting a PCB to have a supporting effect, so that production operation can still be carried out, the practicability is improved, dust generated by routing is treated, and the service life of the PCB is prolonged. And the safety is enhanced.

Description

technical field [0001] The invention relates to the related technical field of PCB gong boards, in particular to a film-attached PCB gong board technology without positioning holes. Background technique [0002] PCB, also known as printed circuit board, is the carrier for the electrical connection of electronic components. In the PCB processing industry, in order to achieve large-scale production and improve production efficiency, multiple PCB single boards can be formed by means of beer boards or gong boards. And the PCB connecting board for sub-board, in which the board is punched out of the predetermined shape on the whole PCB board by the punching machine. Because the edge of the PCB board is smooth and the size is accurate, it has become the preferred technology for PCB board shape processing Way. [0003] Yet existing gong plate technology also has the following problems: [0004] In the production of PCB boards, there will be boards without positioning holes in the ...
