Conductive Die-Attach
PROTAVIC offers a range of adhesive products designed for Conductive Die-Attach.
The choice of the chemistry depends on the final application and requirements:
◾epoxies,
◾acrylics,
◾polyimides
◾or hybrids
The adhesives can be conductive with thermal conductivity up to 28W/mK.
PROTAVIC products have high ionic purity and low degassing, so they are appropriate for use in the defense and aerospace industries.
Some examples are listed in the table below.
