    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 system provided with a solder joint comprises: a circuit board (101) provided with an aperture (102), an electrical component (103) comprising a conductor foot (104) protruding through the aperture, and soldering metal (105) inside the aperture and in contact with the conductor foot. The system further comprises a thermal conductor element (106) comprising a first portion outside the aperture and a second portion inside the aperture and in contact with the soldering metal. The thermal conductor element is capable of conducting heat and thereby it intensifies the heat transfer into the aperture during pre-heating which precedes the process phase when the molten soldering metal is enabled to be absorbed into the aperture. Thus the reliability of the solder joint is improved, i.e. a risk of a faulty "cold" solder is decreased.
