We compared PCB printing to PCB's coat is a bit too, as the saying goes, the clothes make the man, so have a good appearance is the most intuitive feelings users see PCB, because users will look and comment on the stand or fall of a piece of sheet, in addition, screen printing resistance welding and character belongs to the PCB manufacturing process long after the procedure, The value of the printed board is not low after the completion of the process went wrong, the loss is too big, too worthless, again, welding and character is one of the most discarded processes, therefore, the stability of silk screen welding and character process, straighten out the process management and file control and equipment maintenance, it is very important. After 1990, almost all PCB plants did not use traditional processes. There are reasons for this, including: the density of double-sided and printed boards is increasing. The high density of small-hole fine line SMT is an irreversible trend in the development of printed boards. The line width spacing is 0.12~ 0.20 mm

Has been the majority, screen printing thermosetting green oil has been powerless, the appearance is not orderly, oil penetration on the pad, jump print, screen printing staff's proficiency and emotional impact is too big, therefore, most double-sided and multi-layer board factory has eliminated thermosetting epoxy green oil and switch to liquid photosensitive solder ink process.
