In the production process of the circuit board, in order to achieve the effect of insulation between the pads and the lines, and between the lines and the lines. The solder mask process is essential, and the purpose of the solder mask is to disconnect the part to achieve the effect of insulation. Usually many people do not know ink very well. At present, UV printing inks are mainly used for circuit board printing. Flexible circuit boards and PCB hard boards usually use offset printing, letterpress printing, gravure printing, screen printing and inkjet printing. UV printed circuit board inks have now been widely used in the printing of circuit boards (PCB for short). The following introduces three commonly used circuit board ink mimeography methods.

First, UV ink for gravure printing. In the field of gravure printing, UV ink has been selectively used, but the technology and cost have been increased accordingly. With the increasing voice of environmental protection and the stricter requirements for the safety of packaging printed matter, especially food packaging, UV ink will become a development trend of gravure printing ink.

Second, the use of UV ink in offset printing can avoid powder spraying, which is beneficial to the cleaning of the printing environment, and avoids the troubles caused by powder spraying to post-press processing, such as the effect on glazing and lamination, and can Perform connection processing.

Third, UV inks for gravure printing. In the field of gravure printing, UV inks have been used selectively. In flexographic printing, especially in narrow-web flexographic printing, people pay more attention to less downtime, stronger durability Friction, better print quality, etc. The products printed with UV ink have high dot definition, small dot increase and bright ink color, which is a grade higher than that of water-based ink printing. UV ink has broad development prospects.
