TCA connectors or thermally compressed anisotropic (TCA) connectors are not technically connectors, but rather a type of termination technology. This rarely used process was designed in the 1970s for electronic and telecommunications applications. TCA connectors use liquid strips or solid pads made of conductive materials to form solid bonds. This technology can be used for various types of connectors. To connect very high-density connectors through this process, you need to horizontally lay a pad or liquid of this kind on all contacts, and then lay the corresponding pad on top.
Hot compression bonding was first developed in the 1960s and 1970s as a means of bonding metal materials without the need for welding. Early applications were mainly in the aerospace and defense industries, where high reliability connections were essential. TCA connectors are an important development in the development of miniaturized electronic products.
Material specifications: Multiple highly conductive materials are used in TCA connectors, including gold, copper, silver, and nickel. Using adhesives, bonding materials, and films
·Anisotropic Conductive Film (ACF): A thin film with conductive particles applied between surfaces to promote conductivity.
·Anisotropic Conductive Adhesive (ACA): An adhesive that provides conductivity in one direction and is used in conjunction with TCA technology.
