The solder resistance film of printed circuit board is a permanent protective layer. It not only has the function of solder resistance, protection, insulation resistance and so on, but also has a great impact on the appearance quality of circuit board. In the early stage of solder-resistant film printing, the screen pattern was made by using solder-resistant negative film, and then the UV-curable solder-resistant ink was printed.
After each printing, due to wire mesh deformation, inaccurate positioning and other reasons, the residual solder resistance film on the pad takes a long time to scrape, consuming a lot of manpower and time. Liquid photosensitive solder resist ink does not need to make screen graphics, using empty screen printing, contact exposure. This process has high alignment accuracy, strong adhesion, good welding resistance and high production efficiency, and has gradually replaced the photosetting ink.(pcb prototype manufacturer)
