In addition to the inkjet solder resist, Peters will be presenting a white and a yellow inkjet marking varnish at productronica. The marking print is used, for example, to indicate component positions or consecutive serial numbers on the solder resist. The marking lacquer is compatible with the Elpemer and Elpejet solder resist series, ensuring good adhesion to the board. This should also be the case on solder resist masks from the competition.
"The inkjet process conserves resources because a complex screen printing process does not have to be used for every PCB design," says Kevin Poth, Project Manager ELPEPCB. As the inkjet process is a digital process, smaller margins can also be printed. "With the screen printing process, it only pays off from a certain quantity," says paint engineer Kevin Poth.
