Abstract:
A semiconductor device includes wiring boards each having an insulating board, conductor circuits and through-holes, the insulating board having top and bottom surfaces, the conductor circuits formed on the top and bottom surfaces, the through holes penetrating the insulating board and electrically connecting the conductor circuits of the top and bottom surfaces; conductor posts each having flange, head and leg portions, the flange portion having first and second surfaces and having an external diameter larger than that of the through-hole, the head portion protruding from the first surface, the leg portion protruding from the second surface; and electronic components each having an electrode formed on one or more surfaces and connected to the leg portion. The head portion is inserted until the first surface of the flange portion comes into contact with the bottom surface of the wiring board and electrically connected at an inner wall of the through-hole.

A method of producing a laminate insert package includes providing a first metal layer, printing a first dielectric layer on the first metal layer, providing a second metal layer, printing a second dielectric layer on the second metal layer, and printing a dielectric spacer layer on the first dielectric layer. At least one semiconductor chip is attached to either the first or the second metal layer. A first layer assembly comprising the first metal layer, the first dielectric layer, the dielectric spacer layer and a second layer assembly comprising the second metal layer and the second dielectric layer are brought together. The first and second layer assemblies are laminated to form a laminate insert package, whereby the at least one semiconductor chip is embedded within the laminate insert package.

Abstract:
A surface mount circuit protection device includes a laminar PTC resistive element having first and second major surfaces and a thickness therebetween. A first electrode layer substantially coextensive the first surface is formed of a first metal material of a type adapted to be soldered to a printed circuit substrate. A second electrode layer formed at the second major surface includes structure forming or defining a weld plate. The metal weld plate has a thermal mass and thickness capable of withstanding resistance micro spot welding of a strap interconnect without significant resultant damage to the device. The device is preferably surface mounted to a printed circuit board assembly forming a battery protection circuit connected to a battery/cell by battery strap interconnects, wherein one of the battery strap interconnects is micro spot welded to the weld plate of the device.

An electronic device includes at least one semiconductor chip, each semiconductor chip defining a first main face and a second main face opposite to the first main face. A first metal layer is coupled to the first main face of the at least one semiconductor chip and a second metal layer is coupled to the second main face of the at least one semiconductor chip. A third metal layer overlies the first metal layer and a fourth metal layer overlies the second metal layer. A first through-connection extends from the third metal layer to the fourth metal layer, the first through-connection being electrically connected with the first metal layer and electrically disconnected from the second metal layer. A second through-connection extends from the third metal layer to the fourth metal layer, the second through-connection being electrically connected with the second metal layer and electrically disconnected from the first metal layer.

Abstract:
A lead plate-attached coin-type battery is constituted from a combination of a coin-type battery and a positive lead plate. In the coin-type battery, a negative cap seals the aperture of a positive outer can. In a lateral view, the positive lead plate is crank-shaped, and one end thereof is attached to the outer surface of the positive outer can of the coin-type battery. A lead plate is not attached to the negative cap. One or more projections that project in the Z axis direction are provided on the negative cap. In the lead plate-attached coin-type battery, the positive lead plate and negative cap have been attached to respective conductive lands on a circuit board by a solder reflow method.
Abstract:
A press-activated electronic component discharging facilitating apparatus is proposed, which is designed for use with a battery-powered electronic component, such as a CMOS (Complementary Metal Oxide Semiconductor) memory unit installed on a computer motherboard, for providing the CMOS memory unit with a user-operated press-activated discharging facilitating function, and which is characterized by the capability of allowing the user to facilitate the discharging of the CMOS memory unit simply by pressing the battery cell used to power the CMOS memory unit, without having to dismount the battery cell from the motherboard and flip hardware jumpers as in the case of prior art. This feature allows the discharging process of the CMOS memory to be carried out more conveniently and efficiently.
