Problems solved by technology

[0002] After heat treatment, a decarburization layer will be formed on the surface of the copper material. If the decarburization layer is not cleaned off, it will affect the subsequent pickling and phosphating. The formed phosphating film is not dense and has poor bonding force, which will affect the final drawing. , the current carbon removal process has low carbon removal rate and poor uniformity, so it is necessary to improve
