[0002] In the field of electroplating, RTR (Roll-to-Roll) technology is a high-efficiency and continuous processing method, which is particularly suitable for electroplating of flexible materials. However, RTR electroplating lines have the disadvantage of low bubble-type hole breakage. The batch defect rate of hole breakage is about 1.7%, and the in-batch pcs defect rate is about 0.06-1.90%. This has caused a large amount of scrap and increased a large amount of electrical measurement and re-measurement costs. At the same time, it is easy to miss to the downstream, leading to complaints. Therefore, it is urgent to completely improve this type of hole breakage.

[0003] The current RTR electroplating line pretreatment process is as follows: degreasing tank → water washing*3 → pickling → water washing*2 → copper pre-acid → copper tank.
