Aiming at the deficiencies in the prior art, the utility model provides an improved touch screen etching cleaning line, which can avoid material jams in the cleaning process, improve work efficiency, and reduce production costs.In order to achieve the abo
The main process is: dry film-exposure-development-etching-film removal...Dry film: Laminate a dry film on the substrate (copper on the surface). Some use a wet film (that is, ink). The wet film is coated. Because the ink is sticky, it must be pre-baked u
The operating rules for cleaning the LCD screen before PR are as follows: (1) Turn off the power of the washing machine, drain all the cleaning liquid and pure water in the tank, clean the broken glass inside the body, clean the wall of the tank and the d
The developing machine is a printing processing equipment that partially or completely completes the development, washing, gluing, drying and other processes of the printed printing plate through a semi-automatic and fully automatic procedure. Generally c
Most of the etching process involves one or more chemical reaction steps, and various types of reactions are possible, but the common reaction is to first oxidize the surface of the layer to be etched, and then dissolve the oxide layer. With the solution
