Conductive adhesives, conductive adhesives, can effectively bonding various materials, but also has conductive properties. Conductive adhesives include two categories, isotropic the homogeneous conductive adhesive (ICA) and anisotropic conductive adhesive (ACA). ICA is all directions conductive adhesive; ACA is not the same, such as the Z-axis ACA means the conductive adhesive in the Z direction, but not in the X-and Y-direction conductive.

Conductive adhesive is typically used for microelectronic assembly, including the fine wire and a printed circuit, plating backplane, ceramics, a metal layer of the adherend, the metal chassis connection, the bonding wire and the ferrule, an adhesive element and through the plane of the printed circuit hole, bonding waveguide tuning hole patch.

The conductive adhesive can also be used to replace the soldering temperature exceeds the tolerance spot welding due to welding to form an oxide film. Conductive adhesives as a tin-lead solder alternatives, its range of applications such as: telephone and mobile communications systems; radio, television, computer and other industries; automotive industry, medical equipment; solve electromagnetic compatibility (EMC).

Another application of the conductive adhesive is the adhesive used for the electrode sheet with the magnet crystals in a ferroelectric device. Conductive adhesives can replace welding powder and crystal tends to welding temperature deposition welding. The adhesive for the battery post is another use of the conductive adhesive when the welding temperature is unfavorable.

Moreover, the conductive adhesive can be formed a joint of sufficient strength, and therefore, can be used as structural adhesives.

With the rapid development of the electronics assembly industry, conductive adhesive will enter a higher level, namely the development of high conductivity, low thermal resistance, more reliable direction.
