Abstract:
A circuit module (11) is provided with a plurality of dual capacity connector pads (13), each pad holding a miniature surface mount connector (15) and/or a connection pin (17). The preferred I-channel surface mount connector is sufficiently small that the module can be connected by either surface mount connector (15) or pin (17) to the same region of the circuit module.
Abstract:
The flexible connector for high density circuit applications comprises a multi-layer flexible substrate (10) upon which are formed a plurality of contact pads (12), in a density required by a particular application. This density may exceed two hundred contact pads per square inch. Contact pads (38) of similar size and configuration are formed on the surface of another device, i.e., circuit board (40), and provision made to align the contact pads (12) of the connector with those (38) of the circuit board (40). Micro-pads (20) are formed on the surface of the contact pads (12) on the connector such, that when the connector is brought into contact with the circuit board (40), and sufficient pressure is applied, the micro-pads (20) make actual electrical contact with the pads (38) of the circuit board (40). Since the total surface area in contact, namely the sum of the surface areas of the micro-pads (20), is a small fraction of the total area of the connector, a large pressure is provided at the electrical contact interface even when low pressure is provided to the connector as a whole.
Abstract:
The invention relates to a fitted and soldered printed circuit board (1) of a flat assembly on which an additional component (2) is subsequently added and soldered. The printed circuit board has two solder-free fixing holes (7, 8) to fix the ends of the leads (4, 5) of the additional component (2), between which two interspaced soldering pads (10, 11) are placed, enabling said additional component (2) to be fixed onto the printed circuit board (1) and to be electrically connected. The leads (4, 5) have an area (12) running parallel to the surface of the printed circuit board (3) and a second area (14) running perpendicular to said surface, which are inserted into both fixing holes (7, 8).

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.

A printed circuit board (100) and a method (302,304,306,308) for imbedding a battery (106) in the printed circuit board are disclosed. The method includes connecting (302) the battery to a first inner pad (116) and a second inner pad (118) on an inner core layer (104) and forming a first battery contact (122) between a first outer pad (108) and the first inner pad (116). The method also includes electrically isolating (306) the first battery contact (122) and forming a second battery contact (124) between a second outer pad (110) and the second inner pad (118).
Abstract:
Provided is a method for manufacturing a multilayer wiring board, by which interlayer connection is efficiently performed and a non-penetrating hole having a hollow structure or a through hole can be formed at the same time without damaging a plated portion on the inner wall of the through hole. A first printed board (1) is provided with a wiring, which has a wiring section and a bump mounting pad (14), and a substrate section. The method is provided with a step of forming a solder bump (3) on at least a bump mounting pad on the first printed board or a pad section of a second printed board (2) having the pad section (15) by using a solder paste, and a step of bonding the first printed board and the second printed board in layers by having an insulating adhesive (4) between the first printed board and the second printed board and electrically connecting the first printed board with the second printed board.
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.
