MOUNTING OF ELECTRIC PARTS ON CIRCUIT BOARD

摘要

PURPOSE:To obtain an electric parts mounting the method not requiring printing of solder and a process of applying heat on the whole of a product. CONSTITUTION:Anisotropic conductive materials 3a, 3b are pressure-fixed by thermal pressure fixing (pressure, heating) an upper insulation sheet 2 and a lower insulation substrate 1 from up and down for being conducted in the thickness direction in order not only to electrically connect a terminal 4a of an electric part 4 to an upper conductive wiring pattern 2a and the terminal 4a of the electric part 4 to a lower conductive wiring pattern 1a but also to conduction-connect the upper conductive wiring pattern 2a to the lower conductive pattern 1a without through the terminal 4a of the electric part 4.
