Abstract

The invention provides a printing ink hole plugging process method for circuit boards. The printing ink hole plugging process method comprises the following steps: printing ink vacuumizing; screen printing plate production and printing ink hole plugging; printing ink leveling; pre-baking for the first time; exposing for the first time; developing for the first time; subsection baking and curing; surface oil printing; pre-baking for the second time; exposing for the second time; developing for the second time; high-temperature baking. The printing ink hole plugging process method reduces the probability that cracks exist in printing ink, improves the effect of printing ink hole plugging, and avoids the phenomenon that chemicals and humidity in the follow-up process can permeate into empty holes as the cracks exist in the cured printing ink.

Description

technical field [0001] The invention relates to the field of circuit board production, in particular to a process method for ink plugging of circuit boards. Background technique [0002] In today's society, the development of digital electronic products such as mobile phones, computers and cameras is advancing day by day, and is developing in the direction of lightness, thinness, shortness and smallness, and the requirements for the integration of electronic components are getting higher and higher. In particular, the demand for circuit boards is also increasing. In order to meet this demand, the manufacture of circuit boards is gradually developing towards the direction of highly integrated interconnection of line density. a very important step. [0003] The circuit board includes a variety of holes, except for component insertion holes, mounting holes, heat dissipation holes and test holes, most of the other holes do not need to be exposed. The ink plug hole can prevent ...
