ANISOTROPIC CONDUCTIVE SHEET AND ITS MANUFACTURING METHOD

摘要

An anisotropic conductive sheet interposed between a circuit board such as a substrate and circuit components of various kinds and adapted to electrically connect them. The sheet is of fine pitch that recent highly integrated circuit boards and electronic components require, and has a conductivity in only the direction of the thickness of the sheet by using a conductive thin layer so as to prevent conductive members such as of metal from coming off. A method for manufacturing the sheet is also disclosed. An anisotropic conductive sheet (10) is characterized by comprising a conductive thin layer (30) with which the anisotropic conductive sheet (10) is studded along the surface of the sheet (10) and which extends through the sheet (10) in the direction of the thickness of the sheet (30).
