A method of manufacturing flexible loops for microassemblies

摘要

A method of manufacturing flexible loops for microassemblies, including the preliminary manufacture of layered components of loops with conductors deposited on them, characterized in that initially they take the first set of a given number of basic components of a flexible loop on a single base in the form of a preform of a polyimide film coated with a layer of aluminum foil , form on it a given conductive circuit, for which a series of through longitudinal slots is performed by laser cutting, after which the polyimide layer is removed by chemical etching, then they take a second set of compatible components of the flexible loop in the form of a polyimide film with a fluoroplastic layer deposited, on which the windows for contact pads having a transverse orientation are formed by laser cutting, followed by combining the corresponding components of the first and second sets by a group method in such a way so that the contact pad windows of the compatible components of the flexible cable coincide with the edge sections of the conductors of the basic components of the flexible cable, obtained Many sets are connected by thermocompression welding at a temperature in the range 327-335 ° C to obtain an assembly of a group of flexible loops on a single base, then this assembly is divided into individual products by laser cutting.
