Abstract

The invention relates to a circuit board jig which is used for performing ink hole-plugging on a printed circuit board with multiple through holes. The circuit board jig comprises a screen printing plate, a baseboard and a lot of ink, the screen printing plate comprises multiple guide-in holes formed in a manner of penetrating the surface of the screen printing plate, the baseboard comprises multiple grooves formed in the surface of the baseboard, the screen printing plate is arranged on the surface of the printed circuit board, the guide-in holes, the through holes and the grooves are arranged in a one-to-one corresponding manner and in a mutually communicated manner, and the through holes are filled with the ink. The invention further relates to an ink hole-plugging method utilizing the circuit board jig.

Description

technical field [0001] The invention relates to the technical field of circuit board production, in particular to a circuit board jig and an ink plugging method. Background technique [0002] With the improvement and progress of printed circuit board assembly requirements, more and more printed circuit boards require plug holes. The ink plugging process of printed circuit boards is a special process using screen printing developed with surface mount technology. In addition to providing solder mask patterns and surface protection circuits, it also provides convenience for surface mount processes. [0003] The purpose of the ink plug hole is mainly: in the various through holes of the printed circuit board, except for the component insertion hole, installation hole, heat dissipation hole or test hole, the other via holes do not need to be exposed, and the ink plug hole can prevent subsequent Flux or solder penetrates from the soldering surface to the component surface through...
