What Is an Electrically Conductive Adhesive?
An electrically conductive adhesive is a specialized adhesive formulated to create electrical connections between metal components. Distinguished from traditional adhesives, these require conductivity to ensure stable electrical conduction. They achieve this by integrating metal powders such as silver, copper, or nickel into their resin bases to facilitate conductivity. Upon curing, these metal particles form tight bonds, establishing pathways that allow for electron flow.
These adhesives are used across a wide range of electronic devices and electrical components. Applications include attaching electronic components like chip capacitors and resistors to circuit boards, making cable-to-cable and cable-to-terminal connections, grounding metal enclosures and equipment, and aiding in electromagnetic interference (EMI) shielding. The use of electrically conductive adhesives is crucial in ensuring the reliability and functionality of electronic assemblies.
