Electrically conductive adhesive part and its use

Abstract

Abstract PURPOSE: Electrically conductive particles and a thermoplastic resin are mixed in such a proportion that the compound becomes conductive only in the direction pressed and the compound is made into sheets, which facilitate the adhesion of groups of connecting termials oppositing to each other in fine pitch. CONSTITUTION: Electrically conductive particles are mixed with a pasty thermoplastic resin in such a proportion that the compound shows insulating properties in any direction when cured without pressing but it becomes conductive only in the direction pressed when cured with pressing. The mixture is made into sheets ro prepare the conductive adhesive part 6. Conductors 10 .... corresponding to termials 9 .... of itegrated circuit 7 are wired by printing. First, conductive adhesive sheet 6 is placed on the base plate 8 and terminals 9 ... are set thereon and made to coincide with conductors 10 ...., then the adhesive sheet 6 is melted and terminals 9 ... are pressed to conductors 10 .... by heating. After that, heating is stopped and sheet 6 is solidified. Terminals 9 ... are mechanically connected with conductors 10 ... and simultaneously only parts between oppositing terminals 9 ... and conductors 10 ... become conductive.
