The connector blades may also make electrical connections between electrical traces of the first and second printed circuit boards. A method of making an alternate printed circuit board for the assembly involves punching or drilling the alternate printed circuit board to provide a plurality of female terminals in an elongate slot.
Abstract:
An electronic device, comprising an improved printed circuit board connection for connecting a first printed circuit board to a second printed circuit board in a manner that permits physical engagement at a different position than the electrical engagement, and a method for making the improved printed circuit board connection with precision in alignment. In one embodiment, the first printed circuit board includes an end portion configured to engage with a member of a connector on the second printed circuit board. The end portion and the member engage along concave portions of the end portion and convex portions of the member. When engaged, the end portion and the member align wires of the first printed circuit board with terminals of the connector.
Abstract:
A coupling assembly includes a first board and a second board. The first board includes a plurality of first conductive pieces located at an end surface thereof and spaced from one another in a predetermined interval. The second board includes a plurality of second conductive pieces spaced from one another in a predetermined interval and located at at least one end surface thereof close to a lateral edge thereof. The second board includes a plurality of recessed portions recessed inward from the lateral edge thereof and located among the second conductive pieces. The first and second boards are perpendicular to each other. The conductive pieces of at least one of the two boards are provided with soldering. The soldering of each of the conductive pieces is heated to liquate out and then contact the perpendicular corresponding conductive pieces to couple the corresponding first and second conductive pieces with each other.
Abstract:
A fixed resistor network has an insulating substrate, a plurality of film resistors arranged on a top surface of the insulating substrate, terminal electrodes formed for the film resistors on each lengthwise sidewall of the insulating substrate at a given pitch along the sidewall, and recesses provided between the terminal electrodes. The occurrence of solder bridges between the terminal electrodes during solder mounting and the occurrence of chipping in the terminal-electrode-forming areas between the recesses on the lengthwise sidewall are both reduced by making the width of the recesses along the lengthwise sidewall either 0.44 to 0.48 times or 0.525 to 0.625 times the pitch.

Or, a plurality of joint-side terminals are previously held in the insulation housing, and these joint-side terminals are connected with a common flexible wiring member.
Abstract:
A circuit substrate and a method of manufacturing a slot-shaped plated through slot thereon are provided. The circuit substrate has a linear slot. A slot-shaped plated through hole with a multiple transmission paths is formed in the linear slot so that a multiple of signals can be transmitted through the linear slot at one time. The circuit substrate and the method of manufacturing the slot-shaped plated through hole thereon can increase the level of integration of the circuit, decrease the average routing length of the circuit, boost the production efficiency and lower the production cost.
Abstract:
The present invention provides a contact module, a connector, and a method of producing the contact module. The contact module includes a base and a plurality of contacts. Each of the contacts is bent at both ends in one direction. In a section view of each of the contacts, an insulating film, a barrier film, a plating base film, and a plating film are formed on a sheet in this order. The base that bridges the contacts has only the insulating film laminated on the sheet. The plating film has contact points at the bent parts, and a circuit pattern that is interposed between the contact points. The circuit pattern functions as a signal line.
