Main features

  • Improved work life
  • High temperature performance
  • High flow

Product Description

LOCTITE® ECCOBOND FP4460 encapsulant is a silica filled, anhydride material designed for the protection of bare semiconductor devices. It is a low stress, low shrinkage and high flow oven cure product that is considered a glob top version of FP4450 with good ionic purity.

LOCTITE® ECCOBOND FP4460 has no JEDEC rating but its pressure pot performance on live devices is up to 500 hours with no failures, depending on device and package type.

Additional Information

We have internal information showing that these legacy semiconductor liquids pass UL94HB at 1/8” thickness but do not have the test data or yellow card nor are we going to test for it. This is anecdotal but, hopefully, helpful.
