Copper pillar and copper wire oxide layer shelling processing technology

Abstract

The invention provides a copper pillar and copper wire oxide layer shelling processing technology comprising a copper body, a soaking process and a falling process. The soaking process comprises an acid pickling process and a water washing process, the falling process is characterized in that a roller shelling device is used for shelling of the copper body, the roller shelling device is internallyprovided with a rotating shaft, the two ends of the rotating shaft are correspondingly connected with a first roller and a second roller, the copper body is placed at the position, between the firstroller and the second roller, in the roller shelling device for rolling shelling, the copper body obtained after shelling is subjected to an annealing process, the copper body obtained after the annealing process is placed in an acid pickling tank to be subjected to the acid pickling process, and the copper body obtained after the acid pickling process is placed inside a water washing tank to be subjected to the water washing process. The copper pillar and copper wire oxide layer shelling processing technology effectively solves the problem that a copper material for existing copper pillars, copper wires and the like is difficult to be subjected to the oxide layer treatment process in the recycling process, the processes are complicated and hard, and the copper material is damaged during the oxide layer shelling process.

Description

technical field [0001] The invention relates to the field of oxide layers, in particular to a process for peeling off the oxide layers of copper pillar copper wires. Background technique [0002] At present, most metal materials are easy to oxidize, and copper metal materials are often applied to electricity and are more likely to be oxidized and oxidized to cause blackening. The existing oxide layer processing technology of copper metal materials is the most complicated and difficult process in metal oxidation today. The problem. [0003] Existing copper pillars and copper wires are all copper materials. Copper materials can be recycled. After a long period of time, the copper pillars and copper wires are prone to surface oxidation, which makes it difficult to deal with the oxide layer in the recycling process and the oxide layer is falling off. The process is easy to damage the surface of copper pillars and copper wires, thereby affecting production efficiency. Contents...
