Description
Technical Field
The utility model belongs to the technical field of co-plating plates, and particularly relates to a co-plating plate with a strippable copper sheet after electroplating.
Background
With the development of PCB printed circuit board manufacturing technology, traditional planer-type electroplating equipment can not reach the extremely poor requirement of electroplated layer copper thickness. At present, most PCB manufacturing factories replace VCP vertical continuous electroplating equipment to reduce the plating layer extremely poorly, but in order to prevent quality problems such as board burning and the like in the production and processing of PCB printed boards, a certain number of accompanying plating boards are added before and after the production of the boards in the VCP vertical continuous electroplating process to ensure that the produced boards meet the quality requirements.
The accompanying plating plates conventionally used in VCP vertical continuous electroplating are provided with CCL plates and steel plates with certain thickness, the copper thickness of the CCL plates reaches 3-5OZ after 4-6 accompanying plating uses, and then the copper plates are concentrated in discount and take-out sales (because FR4 substrates are clamped in waste accompanying plating plates, dissolved copper is needed to be electrolyzed again in the recovery process, the process energy consumption and the cost are higher, and therefore the discount proportion is lower), and the loss of the substrates and copper generated in the process is more serious. The steel plate and the guide bars in the copper cylinder are frequently scraped in the use process of the steel plate, so that the damage to equipment is serious, and the steel plate is not applicable.
Through the above analysis, the problems and defects existing in the prior art are as follows: the copper on the electroplated surface of the existing accompanying plating plate has higher energy consumption and cost in the recovery process, lower discount proportion and severe damage to equipment caused by the steel plate, and is not applicable.
