High Heat-Resistant Coating Material

Increasing adhesion to sealing materials and reducing internal stress

Increased temperatures in power modules can lead to delamination due to heat-induced stress and weakened adhesion. Traditional methods like roughening lead frame surfaces have limits in preventing delamination with other components. Using a rigid structure to boost heat resistance worsens interfacial adhesion problems.

Resonac's "HIMAL", a heat-resistant coating material used as a sealing material primer, boasting a Tg of 220 degrees Celsius or higher, aims to enhance adhesion, reduce internal stress, and maintain heat resistance, ultimately contributing to higher reliability in power modules.
