Abstract:
The method for the manufacture of multilayer connecting substrates with multiple functions comprises the design of the connecting substrate taking place in functionally separated manner, in that signal conducting substrate parts (19), power supplying substrate parts (2), mechanical substrate parts (7), as well as the arrangement of components (4) or component-carrying substrate parts is separately planned and optimized as independent functions or modules and finally associated with spatially separated functional areas (inner/outer) of the overall circuit, the design taking place by the connection of the modules to an overall circuit embodying the connecting substrate. The resulting multilayer circuit with conductor network (19, 2), components (4) and mechanical stiffening elements (7) has the following structure. The substrate parts with the fine, dense and flexible elements are associated with the inner areas of the overall circuit, the substrate parts with the rigid elements and/or components are associated with the outer areas of the overall circuit and a stiffening support material is so placed in the outer area that the circuit is given a mechanical support structure, which is designed in locally rigid manner passing into flexible areas. The overall circuit is folded and/or wound corresponding to the rigid and flexible portions. The mechanical support structure can be formed by separately produced apparatus housing parts or by the apparatus housing.

As a related aspect, the flex circuit is secured to a head mounting plate which secures the tape head array, thereby forming a stand-alone multi-track tape head module.
Abstract:
A parallel flexible transmission cable accommodating three degrees of displacement and one degree of rotation. The cable has two connectors attached to a flexible, planar cable. A plurality of conductors in the planar cable electrically connect corresponding pins of the two conductors. The cable is bent or formed in the middle of its length to be composed solely of a vane or vanes, that is, planar sections which project othogonally to the common plane of the cable at the connectors. The vanes can flex cooperatively into parallel "S" shapes, allowing the connectors to move transversely with respect to each other. The cable can be made from different normally-planar materials such as flexible circuit boards, or "flex circuits," or ribbon cable.
Abstract:
A plastic multipin connector that provides an optical-electronic interface between the end of a fiberoptic cable and an electronic circuit utilizes a flexible multilayer printed circuit with a ground plane layer on the outside of the folded circuit within a plastic housing and an upright tab intact with the ground plane layer on the outside of the tab and at least one patterned conductor layer. The upright tab is used to make connections of the optoelectronic device with the printed circuit at the base of the device leads to virtually eliminate any lead length from the device to the printed circuit that is not shielded from external noise.
