Abstract
PURPOSE:To make it possible to hold anisotropic conductivity for a long time by using microspheres, wherein the first conductive nickel-plated layer and the second conductive gold-plated layer are formed on each microsphere made of resin, as a conductive agent. CONSTITUTION:Double-plated microspheres wherein the first conductive plated layer made of nickel is formed on the surface of each microsphere made of resin and on its surface the second conductive plated layer made of gold is formed, are dispersed in an insulating adhesive sheet. Thickness of the first conductive plated layer is generally made about 0.02-2mum, because when it is too thick, a surface state gets worse and when it is too thin, coming-off from the microsphere is likely to be caused, while the second conductive plated layer is made about 0.01-1mum thick from view of its price and cracks. These double-plated microspheres are and added dispersed generally by 5-40wt.% to 100wt.% of an insulating adhesive sheet. When it is less than this, anisotropic conductivity is hard to take place, and when it is more than this, adhesive strength is lowered. Thereby, the anisotropic conductive adhesive sheet excellent in durability such as thermal resistance and damp-proofness can be obtained.
