Thermal Curing Solder Mask - Resist for Rigid Boards

For lower resolution requirements down to about 150 microns we offer a range of excellent screen-printable conventional Soldermask. These thermal curing solder resists are usually preferred for high-reliability applications where resolution requirements allow. Various colors and viscosity adjustments help to find the optimum solution for application engineers. The table below represents a cross-section of the available thermal curing Soldermask products. Further information is available by our global or local sales representatives.
