Abstract:
An apparatus such as an appliance with a printed circuit board, PCB, (202) mounted haptic feedback device (200) is provided. The apparatus comprises a printed circuit board (PCB) having an opening (204) defined therein, and a spool (206) affixed to the PCB and having a shaft with a coil (208) wound thereabout. The shaft defines an opening aligned with the opening of the PCB. The apparatus also comprises a spring-loaded plunger positioned and movable within the opening of the shaft. The spring-loaded plunger includes a metallic disk operatively coupled to an end of the plunger and distally positioned to the spool. A control component of the apparatus is configured to energize the coil according to a haptic feedback pattern, and thereby cause the coil to at tract the metallic disk and move the plunger within the opening of the shaft of the spool, and through the opening of the PCB.
Abstract:
A light emitting device according to the present embodiment includes a substrate on which a wiring portion is provided; a light emitting element which is provided on the substrate and is electrically connected to the wiring portion; a feeding portion to which an electric power is supplied from the outside; a first connection portion which is provided on the substrate and is electrically connected to the wiring portion; a second connection portion which is joined to the first connection portion through soldering and includes a first opening portion into which the feeding portion is inserted; and a soldering portion which is provided between the first opening portion and the feeding portion.
Abstract:
Disclosed is a substrate for flip chip bonding, in which a base solder layer is formed between a pad and a metal post, thereby increasing impact resistance and mounting reliability. A method of fabricating the substrate for flip chip bonding is also provided.
Abstract:
An enhanced contact metallurgy construction for plastic land grid array (PLGA) modules and printed wiring boards (PWBs). The PWB may, for example, have subcomposite laminate construction and/or a double-sided LGA site. A plurality of preform contacts are each respectively soldered to one of a plurality of metal pads on a PLGA module carrier and/or a PWB. Each of the preform contacts comprises a metal preform base (e.g., copper, nickel) soldered to one of the plurality of metal pads and an electrolytic noble metal plating (e.g., gold) over the metal preform base. An electrolytic non-noble metal underplating (e.g., nickel) may be interposed between the metal preform base and the electrolytic noble metal plating. In one embodiment, the electrolytic non-noble metal underplating is 80-400 microinches thick to provide an enhanced diffusion barrier, and the electrolytic noble metal plating is 30-60 microinches thick and incorporates one or more hardening agents to provide enhanced wear and corrosion resistance.

Abstract:
A substrate for a semiconductor package and a method of manufacturing the same are provided. More particularly, the substrate for the semiconductor package and the method for manufacturing the same include metal pieces, with some of the metal pieces having one end embedded within an insulating layer for insulating an external connection electrode of the substrate and the other end embedded within a solder. The substrate for the semiconductor package has the effects of preventing or retarding a connection failure in a solder connection portion by blocking or retarding the propagation of a crack, and allowing a solder to be easily permeated under the metal pieces and formed at a desired position.
Abstract:
A metal pad of mode dial and a manufacturing method thereof, wherein the metal pad is disposed on a substrate and the metal pad comprises at least one metal base pad and at least one conductive foil layer. The conductive foil layer is fixed on the metal base pad in an attached way instead of plating with gold on the metal base pad to reduce production costs so as to prevent oxidization of the metal base pad.
Abstract:
Disclosed is a laminated (or non-laminated) conductive interconnection for joining an integrated circuit device to a device carrier, where the conductive interconnection comprises alternating metal layers and polymer layers. In addition, the polymer can include dendrites, metal projections from the carrier or device, and/or micelle brushes on the outer portion of the polymer. The polymer layers include metal particles and the alternating metal layers and polymer layers form either a cube-shaped structure or a cylinder-shaped structure.
