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.
