Cabinet for roll-to-roll conveying selective electroplating flexible printed circuit board and manufacturing process of cabinet

Abstract

The invention provides a cabinet for a roll-to-roll conveying selective electroplating flexible printed circuit board and a manufacturing process of the cabinet. The cabinet comprises a feeding reeling machine, a receiving reeling machine and electroplating equipment, wherein a conveying path for vertically conveying the flexible printed circuit board is formed between the feeding reeling machine and the receiving reeling machine; the flexible printed circuit board is provided with a plurality of circuits, a shading layer and two clamping edges; the two clamping edges are positioned on the upper and lower sides of the flexible printed circuit board respectively; the shading layer is used for shading the flexible printed circuit board and exposing the plurality of circuits and the two clamping edges; and the electroplating equipment is used for selectively electroplating the exposed parts of the plurality of circuits and the two clamping edges of the flexible printed circuit board. The manufacturing process comprises the following steps of: feeding the flexible printed circuit board by using the feeding reeling machine; only electroplating parts to be electroplated, which are exposed out of the flexible printed circuit board, of the plurality of circuits and the two clamping edges when the clamping edges of the flexible printed circuit board are clamped and conveyed into an electroplating bath for electroplating operation; and conveying the electroplated flexible printed circuit board to the feeding reeling machine, and receiving.

Description

technical field [0001] The invention relates to a machine and process for roll-to-roll conveying and electroplating flexible circuit boards, in particular to a machine that uses roll-to-roll conveying flexible circuit boards, and adopts the operation form of selective electroplating, with high Current and insoluble anode plating process on flexible printed circuit boards. Background technique [0002] In response to the increasing consumer demand for electronic consumer products, how to make electronic products thinner, lighter and more humanized is an important topic for future research. Flexible printed circuit boards have the advantages of being easy to bend and low in cost. Nowadays, a large number of electronic products developed are widely using flexible printed circuit boards. At present, most of the flexible circuit boards are still produced in a single non-continuous suspension mode. In the processing process, the appearance quality of the flexible circuit board i...

Problems solved by technology

The flexible circuit board 100' is covered with bare lines 20' to be plated. In the traditional electroplating process, in addition to the shielding area 30', it is necessary to design an accompanying plating area 10' to disperse the current and control the selective plating. Otherwise, it is easy to cause uneven coating thickness, bubbles or burnt problems due to improper control of current, and requires more layout time and the cost of potion
