Abstract:
A method and system for attaching LEDs to circuitry which would protect the LEDs from heat damage and allows for individual LEDs to be removed.
Abstract:
The present invention relates to a light emitting module, which comprises: a main body; a common terminal, in which one side of the common terminal is exposed to the main body and a weldless coupling structure is disposed on the bottom of the common terminal; at least a control terminal, in which one side of the control terminal is exposed to the main body and a weldless coupling structure is disposed on the bottom of the control terminal; and at least a light emitting device. When assembling the components mentioned above, the common terminal and the control terminal are inserted into a through hole of a printed circuit board (PCB), such that the structure can be inlaid into the through hole and a better contact is obtained by its elasticity. Accordingly, the light emitting module can be fastened on the PCB.
Abstract:
A device comprising a workpiece (401) with a surface (401a) including a center (402) and an array of bond pads (420), further an array of interconnects (405) of uniform height. Each of these interconnects comprises an elongated wire loop, which has both wire ends (440, 450) attached to one of the bond pads, respectively, and its major diameter (460) approximately normal to the workpiece surface. A substantial number of the loops has an orientation approximately normal to the vector (410) from the workpiece center to the respective bond pad; this number includes more than 30% of the loops located along the workpiece perimeter and more than 10% of the total loops. Examples of workpieces are a semiconductor device, an integrated circuit (IC) chip, and a semiconductor device package.
Abstract:
An injection molded housing for thick film ignition circuitry used in conjunction with automobile or other vehicle engines includes an integral lead frame for providing electrical connections between the circuitry and engine sensors and ignition components. To provide protection against lead frame failure as a result of vibration and thermal stresses encountered in the engine environment, residual stress cracking caused by varying flexure of the lead frame during the manufacturing process is prevented by utilizing a pre-mold base in which the lead frame is placed prior to subsequent encapsulating of both the lead frame and the pre-molded base. The result is a lead-frame housing construction of greater reliability.
Abstract:
The lead configuration of an electrical component is such that one of the leads locks into position in an aperture of a wiring board when the unit is inserted therein with nominal pressure. This configuration allows the unit to slide only so far into the aperture before it locks in place, thereby prohibiting the unit from being inserted any further, or from falling out of position if the board were inverted. These units remain locked in an upright position on the wiring board for the purpose of being further secured thereon, as by wave soldering.
Abstract:
A solder form facilitates replacement of receptacle terminals that extend through blind connecting through-holes of a plurality of circuit boards. A hairpin conductor within the solder form spreads apart when the form is melted to carry solder to a replacement terminal and to the conductive surface of a throughhole.
Abstract:
A housing, for surface-mount technology (SMT), accepts any electronics package that is mounted on a circular substrate. The housing including the assembled electronics package forms an SMT housing assembly. The SMT housing assembly is placed directly onto the surface of a printed circuit board (PCB). The SMT housing assembly is soldered to the PCB using standard soldering techniques, establishing an electrical connection between the electronics package and the PCB.
