Abstract:
A battery 10A with leads has a low-profile external casing acting 11 as one of a pair of electrode terminals and a closure plate 12 acting as the other of the electrode terminals. The closure plate 12 hermetically seals an opening of the external casing 11 via an insulating gasket. A pair of lead plates 13 and 14 are each welded to a different one of the electrode terminals 11 and 12. One of the lead plates 13 and 14 is secured to a circuit board X. The lead plate 14 that is secured to the circuit board has a net-like structure.
Abstract:
The present invention is an electrode 10 so provided as to be soldered to an electronic component 12 and, when the electronic component 12 is mounted on a substrate 13, soldered to the substrate 13. The electrode 10 includes a column-like electrode body 11 soldered to the electronic component 12 and to the substrate 13. The electrode has grooves as an air discharging device discharging the air 15a in air voids 15 generated within the solder 14 between joint surfaces 11a, 11b of the electrode body 11 and the electronic component 12 or the substrate 13 when the electrode body 11 is soldered to the electronic component 12 or the substrate 13.

A receptacle structure includes a housing structure, a terminal insulating board, a first terminal and a second terminal. The housing structure is configured to be mounted on a printed wiring board and to accommodate a plug. The terminal insulating board includes a top face and a bottom face that is opposite to the top face. The terminal insulating board is disposed inside the housing structure with the bottom face facing towards the printed wiring board. The first terminal is connected to the printed wiring board via the first rear connection part and to the terminal insulating board. The second terminal is connected to the printed wiring board via the first front connection part and to the terminal insulating board. The first front connection part has a width narrower than the first rear connection part and is connected to the printed wiring board away from the first rear connection part.
Abstract:
In a method of bonding a first bump on a surface of a first member and a second bump on a surface of a second member, a tip portion of the first bump is provided with a projection having a hardness greater than a hardness of each of the first and second bumps. The first and second members are positioned with respect to each other such that the first and second bumps face each other. The tip portion of the first bump is brought into contact with a tip portion of the second bump by sticking the projection into the tip portion of the second bump.
Abstract:
A reinforcing plate fixed to a connector main body is arranged on a bottom surface of the connector main body to come into surface contact with a surface of a substrate while a plurality of holes is provided on a surface, which contacts the substrate, of the reinforcing plate. When the reinforcing plate is soldered to the substrate, therefore, a solder wraps around not only a peripheral edge of the reinforcing plate but also an edge of each of the holes so that a soldering portion between the reinforcing plate and the substrate can be sufficiently ensured.

The present disclosure is directed at an apparatus for changing printed circuit board pad structure to increase solder volume and strength. The invention provides increased end row pad and lead size and utilizes a plurality of lead-to-pad and pad-to-lead conforming geometric structures to form a joint providing additional solder surface adhesion area.
Abstract:
A manufacturing method of a contact structure includes first providing a substrate on which a contact pad has already been formed. Afterwards, a polymer bump is formed on the contact pad. Next, a conductive layer is formed on the polymer bump. The conductive layer covers the polymer bump and extends to the outside of the polymer bump. The portion of the conductive layer extending to the outside of the polymer bump serves as a test pad.

Provided are an embedded capacitor, an embedded capacitor sheet using the embedded capacitor, and a method of manufacturing the same that may increase a surface area to thereby increase a capacity for each unit area and may provide an embedded capacitor in a sheet to thereby readily lay the embedded capacitor on an embedded printed circuit board. The embedded capacitor may include: a common electrode member 11 including a plurality of grooves 11a; a sealing dielectric layer 12 being formed by sealing a nano dielectric powder with a high dielectric constant in the plurality of grooves 11a formed in the common electrode member 11; a buffer dielectric layer 13 sealing and smoothing an uneven portion of the sealing dielectric layer 12 by applying a paste or a slurry including epoxy of 20 Vol % through 80 Vol % and dielectric powder of 20 Vol % through 80 Vol % with respect to the sealing dielectric layer 12; and an individual electrode member 14 being formed on the buffer dielectric layer 13.
Abstract:
A method and a surface mount technology (SMT) pad structure are provided for implementing enhanced solder joint robustness. The SMT pad structure includes a base SMT pad. The base SMT pad receives a connector for soldering to the SMT pad structure. A standoff structure having a selected geometry is defined on the base SMT pad to increase thickness of the solder joint for the connector.
