Abstract
An inkjet method for producing a solder mask in the manufacture of a Printed Circuit Board uses a solder mask inkjet ink containing at least one photo-initiator, at least one free radical polymerizable compound and at least one RAFT compound as adhesion promoter. A high quality solder mask withstanding the high thermal stress during the soldering process while maintaining excellent physical properties is produced.
