Abstract:
A multilayer capacitor which can prevent chattering noises from occurring and improve the packaging density and packaging yield, and a method of manufacturing a multilayer capacitor are provided. Even when an electrostrictive vibration is generated in this multilayer capacitor upon voltage application, a joint surface of a metal terminal can flex, so as to mitigate the electrostrictive vibration, thereby preventing chattering noises from occurring. The joint surface is formed with a cutout and thus can fully secure its flexibility. In this multilayer capacitor, a step formed by a terminal connecting surface, a substrate connecting surface, and the joint surface is positioned within an area overlapping a capacitor element body as seen in the laminating direction of dielectric layers. Therefore, solder fillets do not protrude out of the capacitor element body, whereby the packaging density on a mounting substrate K can be improved. The state of solder fillets is easy to see from the outside, and a connection yield can also be secured.
Abstract:
In order to mechanically and electrically connect two printed circuit boards (26, 27) in a parallel arrangement, a plurality of connecting elements (1) is arranged in an insulating member (22) having parallel faces, said connecting elements projecting from both opposite faces of the insulating member. The projecting part of the connecting elements is designed as a contact element (6), thus allowing said contact elements to be plugged into plated-through bores (28) of the printed circuit boards. The contact elements are secured within the plated-through bores by means of a clamping force acting transverse to the plugging direction. The clamping force causes the contact elements to be pressed against the walls of the plated-through bores and thus both mechanically secures the contact elements and establishes an electric connection. According to the invention, the clamping force of the connecting elements is greater for one printed circuit board than the clamping force of the connecting elements for the other printed circuit board so as to ensure that the insulating member remains plugged in one of the printed circuit boards along with the connecting elements contained in the insulating member when the connection is released.

A printed board includes a printed board body having a first side, a second side opposing the first side, and a through-hole; a printed conductor disposed on the first side of the printed board body; and a bus bar disposed on the second side of the printed board body, the bus bar including a terminal that extends through the through-hole. The terminal includes a plurality of branched terminal portions at a position corresponding to an interior of the through-hole, and at least one of the branched terminal portions is bent and attached to the printed conductor.

Abstract:
A method and product produced includes a power layer board that is manufactured by providing a printed circuit board having an input configured to receive an input power and an output configured to deliver an output power conditioned to power a motor. The method also includes soldering a first component to the printed circuit board. Thereafter, a request to manufacture the power layer board is received that includes parameters of the input power and/or the output power. Therefrom, characteristics of a second component including a resistor, a capacitor, and/or an inductor is identified based on the parameters of the input power and/or the output power. Accordingly, the identified second component is mounted to the printed circuit board through a solder-less cold-weld connector to complete the power layer board.

Abstract:
a method of making a printed circuit board including the steps of: providing a board with electrical conductor traces; applying a solder material to at least one selected location on a first side of the board; placing a first component on the first side of the board; heating the board and solder material to reflow the solder applied to the first side of the board to provide an electrical connection of the first component with a first conductor trace portion of the board; and then connecting a second component to the board and providing a nonsoldered electrical connection between the second component and a second electrical conductor trace portion of the board.
Abstract:
A package for a fiber optic transceiver that integrates the intermediate rear gasket into the lower body of the transceiver package. As such, the EMI fingers are much thicker than current art EMI fingers, 0.010″ thick as compared to current art 0.002″ thick. In current art devices, providing such robust EMI fingers is not possible. The connecting pins that secure the transceiver cage to the PCB are self-centering press-fit pins formed from a plurality of legs. At least one of the legs provides an electrical connection point for the transceiver on which the pins are used. The connecting pin is formed so that the legs act as leaf springs to securely hold the connector in place in the proper installation hole in the board on which the transceiver is installed. The pins are stamped from sheet metal with a progressive die process. By changing the amount of flexion in the legs of the pin, the pressure required to insert the pin into a connection hole, and hence the retaining pressure, can be varied.
