By inserting the film between electrode patterns and heat-pressing it, the film exhibits conductivity in the thickness direction and insulation property in the plane direction.

定な導電性を示すと考えられる。Anisotropic conductive film uses nickel powder as conductive particles,
Solder powder or spherical particles made of metal-plated plastic beads are used, and conduction occurs when they come into mechanical contact with electrodes. However, in the type that uses solder powder, the particles are soft, so the shape after crimping is the same as before crimping. The contact area increases by being crushed to about 1.5 to 4 times the diameter of the lead, and the insulating resin that acts as a binder fixes this between the connection terminal and the lead, exhibiting stable conductivity. In the case of beads with metal plating, the mechanism is thought to differ depending on the hardness of the original plastic beads. That is, in the case of soft particles, the particles are changed from spherical to elliptical and are fixed between the connection terminals by the binder resin while retaining repulsive force, and exhibit stable conductivity. On the other hand, in the case of hard particles, the plated conductive particles are crimped by sinking into the metal or metal plating layer of the electrode of the printed wiring board for mounting semiconductors, and are further fixed to the connection terminals and leads with a binder resin. , it is thought to exhibit stable conductivity.
