The invention relates, among other things, to an assembly (10), comprising an electric conductive track carrier (20) and a component (30) arranged on the conductive track carrier. According to the invention, the component is a fiber-optoelectronic component and comprises: a housing (40), at least one electro-optic or optoelectronic component (50), at least one fiber-optic interface (60) connected to the electro-optic or optoelectronic component, and at least one electric interface (80) for connecting the component to the conductive track carrier, wherein the electric interface comprises at least one bent electric soldered connection element (100), the one end (110) of which is attached to a bottom connection section (120) of the housing bottom (125) and from there extends laterally outwardly such that the other end (130) of the soldered connection element – as viewed from above – protrudes laterally and is laterally soldered to the conductive track carrier outside of the outer housing contour (140), and wherein the soldered connection element is bent away from the bottom connection section such that the bottom connection section has a distance (A) from the conductive track carrier.
Abstract:
A process for forming a laminate with capacitance and the laminate formed thereby. The process includes the steps of providing a substrate and laminating a conductive foil on the substrate wherein the foil has a dielectric. A conductive layer is formed on the dielectric. The conductive foil is treated to electrically isolate a region of conductive foil containing the conductive layer from additional conductive foil. A cathodic conductive couple is made between the conductive layer and a cathode trace and an anodic conductive couple is made between the conductive foil and an anode trace.

Abstract:
An electroconductive circuit, in which a masking material and a base both have a low dielectric loss tangent to a high-frequency signal and have excellent adhesion to each other, can be formed in a simple and low-cost manner. A cycloolefin resin with a flexible polymer mixed and dispersed therein is injection molded to form a primary base (1), and a cycloolefin resin, in which a compatible flexible polymer has not been mixed, is injection molded on the surface of the primary base (1) to form a masking layer (2). Since the cycloolefin resin per se has etching resistance, for only the surface of the primary base (1) not covered with the masking layer (2), that is, only a part (1a) on which an electroconductive circuit is to be formed, the flexible polymer is dissolved for roughening and only the part (1a) can be rendered hydrophilic. Accordingly, an electroconductive layer (4) can be selectively formed by electroless plating only onto the part (1a) not covered with the masking layer (2).

A solid printed circuit board is manufactured by bonding upper and lower printed circuit boards having different shapes and provided with wirings formed on surfaces thereof. A bonding layer is made of insulating material containing thermosetting resin and inorganic filler dispersed therein, and has a via-conductor made of conductive paste filling a through-hole perforated in a predetermined position of the bonding layer. This circuit board provides a packaging configuration achieving small size and thickness and three-dimensional mounting suitable for semiconductors of high performance and multiple-pin structure.
Abstract:
In order to improve the adhesion of a circuit to a circuit forming board, a separation film (4) comprising a base film and a coating layer formed on the base film is joined to both the sides of the board (1). When a laser beam (5) is applied to form a throughhole (6) in the board (1), a unified portion (7) of the board (1) and the separation film (4) is formed around the throughhole (6). An energy beam is applied to the whole or a part of the surface of a circuit formed at a circuit forming step to transfer a part of the separation film. Thus, a high density board where the circuit strongly adheres to the board can be realized in the manufacturing process of the circuit forming board.
