Abstract:
A manufacturing method for a component incorporated substrate according to the present invention includes positioning an electronic component (14) with reference to a mark (12) formed on a copper layer (4), the mark (12) consisting of a material less easily etched than copper by a copper etching agent used for etching of copper, after mounting the electronic component (14) on the copper layer (4) with an adhesive layer (18) interposed therebetween, embedding the electronic component (14) and the mark (12) in an insulating substrate (34), thereafter, etching and removing a part of the copper layer (4) to form a window (W1) for exposing the mark (12), forming an LVH (46) reaching a terminal (20) of the electronic component (14) with reference to the exposed mark (12), electrically connecting the terminal (20) and the copper layer (4) via a conduction via (47) formed by applying copper plating to the LVH (46), and, thereafter, forming the copper layer (4) into a wiring pattern (50).
Abstract:
A device includes an electrical connector coupled to the end of a flex circuit. The connector includes interior ribs that engage slots in the flex circuit, with the ribs and slots separating adjacent contact pads on the flex circuit. The contact pads are exposed portions of conductive traces on the flex circuit. Other portions of the conductive traces may be covered by a dielectric material, such as a non-conductive ink. The ribs provide an increased isolation path between the contact pads.

Abstract:
A method of manufacturing a multilayer flexible circuit comprises providing first and second flexible substrates, each comprising a conductor layer and an insulator layer. The conductor layer of the first substrate is a patterned conductor layer. The first and second substrates are laminated together using a double belt press through which the substrates move in a continuous process. The method may include patterning the conductor layer of the first substrate and/or the conductor layer of the second substrate using an etching method that includes exposing a dry film resist on the conductor layer to a pattern by carrying out a plurality of exposures of adjacent and/or overlapping areas.
