Coating process for flexible circuit board production

Abstract

The invention relates to the technical field of circuit board film coating, in particular to a film coating process for flexible circuit board production, the film coating process for flexible circuit board production is based on a processing device, and the film coating process for flexible circuit board production comprises the following steps: step 1, sequentially hanging a plurality of flexible circuit boards to be coated on a tool frame, six to eight circuit boards can be hung on the tool frame at a time; the driving motor drives the driving shaft and the mounting bracket to rotate, the mounting bracket rotates to drive the fixed sleeve and the circuit board to rotate, the fixed sleeve rotates to drive the rotating gear to rotate on the fixed gear ring, and the fixed gear ring rotates to drive the fixed sleeve, the sliding rod and the circuit board to rotate. According to the circuit board coating device, a plurality of circuit boards can rotate in the rotating process, coating of the circuit boards is more uniform, the coating effect on the circuit boards is improved, a rotating support rotates to drive a fixed rod, a movable cylinder and a scraping plate to rotate, and scraping on the inner wall of a processing box body is achieved.

Description

Technical field [0001] The present invention relates to the field of circuit board coating technology, specifically a flexible circuit board production coating process. Background [0002] With the rapid development of economy and industry, for the product surface of a variety of improved mechanical strength, decoration or other special performance processing needs gradually emerged on the table, electroplating is the use of electrolysis principle on some metal surface plating on a thin layer of other metals or alloys process, is the use of electrolysis to make the surface of metal or other materials attached to a layer of metal film process so as to prevent metal oxidation, improve wear resistance, conductivity, reflectivity, corrosion resistance and improve the appearance and so on. [0003] After searching for the publication number CN213739640U utility model patent, disclosed a circuit board coating device, including the main box, the main box front is provided with a box doo...

AI Technical Summary

Problems solved by technology

[0005] In the coating process of existing flexible circuit boards, most of the circuit boards cannot rotate, resulting in uneven thickness of the circuit board coating, resulting in the formation of pits or corrugated strips on the coating, which reduces the quality of the circuit board coating
