The invention belongs to the technical field of FPC solder
resist printing, and particularly relates to a device for realizing a one-time
screen printing function through screen attaching and secondary
coating. The device is provided with a screen body and a screen tray, and the top surface of the screen tray is provided with a containing groove. The method comprises the steps that the screen body is placed in the containing groove and fixed through a fixing
assembly; a layer of photosensitive water film is attached to the surface of the screen body, and then primary local
exposure is carried out; and the photosensitive water film subjected to primary local
exposure is coated with a layer of photosensitive
resist, and then secondary local
exposure is carried out. According to the
processing method, a layer of photosensitive water film is attached to an existing screen, local exposure is carried out, then photosensitive glue is coated, secondary
coating is carried out, and local exposure is carried out, so the one-time
screen printing function is achieved, the customer requirement is met, the product efficiency is improved, the one-
machine multifunctional printing effect is achieved, meanwhile, the labor cost is reduced by 50%, the material cost is reduced by 50%, and the product productivity is synchronously improved by 50%.
