ELECTRICALLY CONDUCTIVE ADHESIVE
Electrically conductive adhesives (ECAs) have been developed as a way of replacing tin-lead solder in the assembly of electronic circuits. The metal filler can be particles or flakes of silver, gold, nickel, copper or carbon, in sufficient quantities to ensure good electrical conductivity.
