Underfill
Underfill is a liquid resin that works by capillarity to protect components from shocks, drops and vibrations.
The insulating filling improves the reliability of the weld points, particularly during thermal stress and drop tests.
The low thermal expansion of PROTAVIC Underfill makes it effective in a variety of uses.
Some examples are listed in the table below.
