Exposure method for exposure process of single-sided circuit board substrate

Abstract

The invention discloses an exposure method for the exposure process of a single-sided circuit board substrate, which comprises the following steps: 1) Changing the exposure process from the upper light exposure method to the lower light exposure; 2) Sticking the film on the 3) Paste the circuit board substrate on the film in reverse for exposure. The rapid etching method of the single-sided circuit board of the present invention is simple to operate, can improve work efficiency, double production efficiency, and can save various costs. The exposure method of the single-sided circuit board substrate exposure process of the present invention is easy to operate, and can be completed independently by one operator; the production efficiency of equipment can be improved, and not only the cost of the film but also the labor cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of circuit board production, in particular to an exposure method in the exposure process of a single-sided circuit board substrate. Background technique [0002] The exposure process is mainly based on the engineering data to make the corresponding film, and then the film is aligned with the board through the positioning nails, and finally it is completed by ultraviolet light irradiation in the exposure machine. In the early stage, the light exposure has been used, two people operate, one The operation process is cumbersome for one exposure. A single material number requires two sets of production materials according to the size of the exposure table. Two people operate at the same time, resulting in an increase in labor costs, but the output does not increase. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies of the prior art, the present invention aims to ...
