MOUNTING BODY MANUFACTURING METHOD AND ANISOTROPIC CONDUCTIVE FILM

摘要

A method for manufacturing a mounting body comprising: a mounting step of mounting an electronic component onto a wiring board via an anisotropic conductive film containing a binder having an epoxy resin as a primary constituent and conductive particles having a compressive hardness (K) of 500 kgf/mm2 or more when compressively deformed by 10%, wherein a relation between a thickness (A) of the binder and an average particle diameter (B) is 0.6≦B/A≦1.5 and an elastic modulus of the binder after curing is 50 MPa or more at 100° C.; and a remounting step of mechanically peeling to detach the electronic component and the wiring board in the case of a problem occurring in mounting of the mounting step and reusing the wiring board to perform the mounting step.
