FLEXIBLE SOLDER MASK

Background

Flexible solder masks and functional coatings applied in a casting, spraying, or screen printing process. There are protective coatings, marking lacquers, and functional coatings for PCBs.

Applications

  • Flexible solder masks with various properties such as protection, electrical insulation, and marking in different colours
  • Functional lacquers such as plugging and drawing lacquer, silver paste, resistive inks, and thermal pastes

Benefits

  • Protection of conductor tracks from corrosion, electrical insulation, and mechanical damage
  • Closing of via holes
  • Fabrication of defined resistances
  • Marking as per customer requirements, e.g. for assembly

Special features

  • Solder mask and legend print available in various colours
  • Highly temperature resistant lacquers
  • Complete closing (overplating) of via holes and blind vias
  • Application of removable protective lacquers in accordance with customer specifications
