What is an Electrically Conductive Adhesive?

Electrically conductive adhesives (ECA) are usually thermal or room-temperature curing epoxy or thermoplastic resin based adhesives which contains metallic fillers for electrical conductivity. These metallic fillers can be nickel, copper, silver or gold. Adhetron’s electrically conductive adhesives contains silver granules for optimum electrical conductivity.

Electrical conductive adhesives (ECAs) used as an alternative for soldering process. Thanks to their low temperature curing process, electrical conductive adhesives creates conductive bondlines for heat sensitive components which cannot connected by soldering.

Electrical conductive adhesives also used for EMI (electromagnetic interface) and RFI (radio frequency interface) shielding for protecting components from electromagnetic radiation.

Another usage area of electrically conductive adhesives are grounding the sample to avoid electrostatic charging of the surface.
