The invention provides an inkjet method for producing a solder mask in the manufacture of a Printed Circuit Board. By using a solder mask inkjet ink containing at least one photo-initiator, at least one free radical polymerizable compound and at least one allyl sulfone compound as adhesion promoter, a high quality solder mask withstanding the high thermal stress during the soldering process while maintaining excellent physical properties, may be produced.
本发明提供了一种在印刷电路板制造过程中生产焊接掩模的喷墨方法。通过使用含有至少一种光引发剂、至少一种自由基可聚合化合物和至少一种烯丙基砜化合物作为附着力促进剂的焊接掩模喷墨墨水,可以生产出高质量的焊接掩模,既能承受焊接过程中的高热应力,又能保持良好的物理性能。
