Conductive Adhesive Paste

What is Conductive Adhesive Paste?

Conductive adhesive pastes are adhesives designed to conduct electricity or heat, encompassing a range of specially formulated adhesives for specific conductivity purposes. Conductive adhesive pastes can be categorized into different types, such as silver conductive adhesive paste, conductive carbon paste, conductive copper paste, conductive silicon paste, conductive nickel paste, and epoxy-based adhesives.

Electrically conductive adhesives typically contain metal particles (like silver, copper, gold, etc.) that have high conductivity and surface area. These are often used to create electrical connections. On the other hand, thermally conductive adhesives assist in efficiently transferring heat, aiding in the cooling of components. These thermal adhesives are often enriched with materials that have high thermal conductivity properties, such as aluminum oxide or boron nitride particles.

Applications and Importance

Conductive Adhesive Pastes find significant use in the electronics sector, particularly for attaching surface-mounted devices (SMDs) to printed circuit boards (PCBs) and bonding semiconductor dies. Their advantages include compatibility with temperature-sensitive components and potential for use in flexible electronics. Additionally, they play roles in electromagnetic shielding and solar cell assembly.
