A kind of reusable electroplating method for accompanying plate

Abstract

The invention relates to the technical field of printed circuit boards, in particular to a reusable electroplating method for accompanying plating boards. When the present invention uses VCP to carry out the electroplating process to the production board, use the accompanying plating plate with electroplated nickel-gold layer as the etching protection layer, and make the accompanying plating plate go through alkaline once when the production board of each line completes the electroplating treatment. Etching line, remove the copper layer formed on the surface of the accompanying plated plate during the electroplating process through etching, so that the accompanying plated plate can be restored to the state before use, so that it can be re-used in the electroplating process, realizing the reuse of the accompanying plated plate, completely avoiding It solves the problems that the existing accompanying plated plate will deteriorate in appearance and become heavier and thicker as the number of times of use increases, which will cause the accompanying plated plate to drop, fixture damage, copper cylinder pollution and other problems during the electroplating process, which can reduce production costs and improve production efficiency. 10 The production capacity of 10,000 square meters can save about 15,000 yuan in the production cost of accompanying plated plates.

Description

technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to a reusable electroplating method for accompanying plated plates. Background technique [0002] In the production of circuit boards, electroplating is almost an essential process. At present, electroplating is usually carried out using gantry electroplating lines or vertical continuous electroplating equipment (VCP), and due to the safety and economy of vertical continuous electroplating equipment, it replaces gantry electroplating lines. has become an inevitable trend. [0003] When using vertical continuous electroplating equipment for electroplating, in order to ensure that during the electroplating process of the production board, the first board and the last board in each line of production boards will not cause burn-in problems due to excessive current. Add a plating plate before one plate and after the last plate. At present, the accompanying plate used for...

Problems solved by technology

[0005] The present invention aims at the problem that the accompanying plating plate used in the current VCP electroplating cannot be reused for a long time, which leads to the increase of electroplating cost and affects the production efficiency, and provides an electroplating method in which the accompanying plating plate can be reused so as to improve the production efficiency of electroplating and reduce the production cost
