SuperWhite LED Soldermask

  Current Resin System   Desired Resin System
  Focus: initial thermal shock, not constant heat   Remains white through assembly and lifespan
  Tend to brown over time   High reflectivity to enhance performance
  Not developed as LED reflecting surface   Result: lower power consumption

Solution: White Hot Temperature LED Soldermask

During the past two years a number of LED white solder masks have been introduced. Unfortunately, we didn't see much of an improvement. That is why we have innovated our own solutions and identified two offerings that demonstrate significant improvements.

Achieving SuperWhite Soldermask While Resisting Browning

One way to achieve a "SuperWhite" solder mask that resists browning is to apply a second coat of thermal cured white soldermask over the LPI. However, this can cause a concern that the second coat may impede the thermal dynamics of the PCB surface.
