Passivation Resist

EP3912 forms a high humidity and high temperature resistant coating. It offers protection against metal plating processes and subsequent Pb-free assembly of the final package. It can be applied by screen-printing although formulations for other application methods (air-spray and spin-coat) are available. EP3912 It is normally used as a barrier layer underneath the solvent soluble, photo-definable die-passivator, EP2793.

  • LSF60 WLP Photodielectric & Soldermask

    LSF60 is a liquid, photoimageable two component soldermask designed for use on high definition CSP/WLP Packages. LSF60 has a long track record of use in WLP applications where final components must pass stringent High Temperature Storage (2000 hours at 150°C), Thermal Cycling (1000 cycles -40°C to 125°C) and Moisture Sensitivity (2000 hours 85°C/85% RH) tests. Versions are available for application by screen printing and spin-coat. Excellent resolution and side-wall profile control. Compatible with lead-free processing. Suitable for electrolytic/electroless gold plating. Thermal cycling & crack resistance. Suitable for high temperature storage. 12 month shelf-life. Halogen-free, RoHS and fully REACH compliant with no TGIC or other SVHC content.
