Electrically conductive adhesives have been widely used in many applications, such as die attaching, electronic packaging, surface mounting applications, RF grounding, EMI shielding, solar panel assembly, and so on. Traditionally, these adhesives are liquids/pastes and need dispensing or printing processes for application. Typically, they have short work life and open time. It's difficult to set and ensure a uniform void-free bonding line thickness across a large area. In addition, advanced semiconductor devices such as Gallium Nitride (GaN), Gallium Arsenide (GaAs) and Silicon Carbide (SiC) can safely operate at elevated operating temperatures, which many traditional adhesives cannot withstand.

Understanding these limitations, Henkel developed a new product combining excellent workability of B-stageable state and high temperature-stable resin technology. This product is Loctite Ablestik CF3366, a silver filled epoxy film adhesive. Its well-controlled film thickness and B-stageable characteristics offer excellent workability in terms of bonding line control and work life. This product contains rubberized particles to balance flexibility and adhesion strength and offer high adhesion strength at elevated temperatures.

These unique characteristics make it an excellent choice in RF grounding applications, especially for harsh environmental conditions.

Webinar attendees will learn about this new product, including its excellent workability and superior high temperature performance.
