CONDUCTIVE ADHESIVE

摘要

PURPOSE:To obtain a conductive adhesive which can prevent the bending or cracking of a semiconductor pellet and is useful for bonding a semiconductor pellet with a tub by using a specified addition reaction-curing conductive silicone rubber composition. CONSTITUTION:This adhesive is prepared from an addition reaction-curing conductive silicone rubber composition containing at most 500ppm of a low- molecular siloxane having a vapor pressure >=10mmHg at 200 deg.C [e.g. a compound of formula I or II (wherein (n) is 3-25; and (m) is 1-25)] (e.g. a composition obtained by mixing a vinylated polysiloxane with an Si-bonded H-containing polysiloxane, a silver powder and a chloroplatinic acid/olefin complex).
