A circuit-terminal connecting device comprising a first connector (12) having a first housing (15) fixed to a main circuit board (11) and first contacts (16) supported by the first hous i ng (15) to be connected with first circuit-terminals provided on the main circuit board (11) and a second connector (14; 40) having a second housing (17; 41) attached to a flat circuit member (13) and second contacts (18; 42) supported by the second housing (17; 41) to be connected with second circuit-terminals (20) provided on the flat circuit member (13). The first housing (15) of the first connector (12) fits into a hole (22; 44) formed in the second housing (17; 41) of the second connector (14; 40) so as to create an electrical piling connection between the main circuit board (11) and the flat circuit member (13) wherein the flat circuit member (13) is laid on top of the main circuit board (11) and the first circuit-terminals are electrically connected with the second circuit-terminals (20) through the first and second connectors (12, 14; 40).
Abstract:
A circuit board connection structure and a circuit board in which only the surplus portion of the anisotropic conductive adhesive between connection sections opposed to each other is smoothly and adequately discharged. In the circuit board connection structure (10), first and second connection sections (13A, 14A) are opposed to each other with an anisotropic conductive adhesive (16) interposed between the sections and are interconnected. The line (26) connecting a first end (19A) of a first wiring pattern of a first base and a first end (39A) of a second wiring pattern of the first base crosses at predetermined angle with respect to the arrangement direction parallel to the width directions of the first and second wiring patterns (19, 39) of the first base.
Abstract:
A power electronic module (10) includes heat generating power electronic devices (40-52) mounted on a circuit board (12) within a connector outline (34) circumscribing circuit board through-holes (26) for receiving pin terminals (22) of a connector assembly (18). The power electronic devices (40-52) are thermally and electrically coupled to the circuit board through-holes (26) and connector pin terminals (22) to dissipate heat generated by the power electronic devices (40-52).
Abstract:
A groove and a recess are formed on one surface of a base material, the recess being communicated with the groove and having a width and a length longer than a width of the groove. After that, liquid droplets are landed on the recess to charge a liquid into the groove communicated with the recess. Further, the liquid charged into the groove is solidified. Accordingly, the liquid can be charged into the groove having the narrow width, by merely landing the liquid droplets on the recess having a large areal size. Therefore, a fine pattern can be easily formed on the base material.
Abstract:
A method for producing contact pads on pattern boards (8) comprises a plating treatment in order to apply electrically conductive material on the board in correspondence to the desired contact pads (31). The electrically conducting material on the contact pads is subjected to a treatment with an agent capable of etching the material in order to provide chamfering or rounding of peripherical edges (34) of the contact pads.
Abstract:
A connection housing includes a base body with lateral walls, which extend around the base body on top and which enclose the component to be inserted as well as inner contacts that are arranged between the component and at least one lateral wall. Polymer protuberances for forming outer contacts are shaped onto the underside. The connection between the inner contacts of the top and the outer contacts of the underside is effected by micro-boreholes that are located underneath the component in the middle area of the base body. This results in the provision of a housing, which requires little space on a printed circuit board and which can be economically produced preferably while using laser structuring.

Abstract:
A circuit board assembly is described. The assembly comprises a module (2) which comprises a first substrate (7) having first and second faces (8, 9), a first conductive region (11) disposed on the first face of the first substrate and a hole (14) in or adjacent to the first conductive region and passing through the first substrate between the first and second faces. The assembly also comprises a circuit board (3) which comprises a second substrate (4) having first and second faces (5), a second conductive region (6) disposed on the first face of the second substrate. Conductive ink (15) is disposed in the hole and between the first and second substrates. The module is mounted to the circuit board and is arranged such that the hole lies over or adjacent to the second conductive region and the conductive ink provides an electrical connection between first and second conductive regions.
Abstract:
Multichannel RF Feedthroughs. In some examples, a multichannel RF feedthrough includes an internal portion and an external portion. The internal portion includes a top surface on which first and second sets of traces are formed. Each set of traces is configured as an electrical communication channel to carry electrical data signals. The external portion includes a bottom surface on which the first set of traces is formed and a top surface on which the second set of traces is formed. A set of vias connects the first set of traces between the top surface of the internal portion and the bottom surface of the external portion.
