A circuit-carrying automotive component and a method of manufacturing the same are provided. In a preferred embodiment of the invention, the component includes a substrate made from a polymer that is molten at a predetermined elevated temperature. The component further includes a circuit board which defines an aperture therethrough adapted to receive the molten polymer at the elevated temperature and a fastener formed from the molten polymer through the aperture. The fastener is integral with the substrate and mechanically secures the circuit board to the substrate. The circuit board is made from a material that is resistant to fusing with the molten polymer at the elevated temperature.

An on-board chip package has a hermetically sealed connector mechanically secured to a printed wiring board and electrically connected to input/output pads on the board. Chip dies are mechanically bonded to the board and then individually encapsulated with a suitable potting material. The entire assembly is coated with an encapsulating polymer, which partially overlaps the inboard side of the hermetic connector housing and which provides a relatively smooth, crevice-free outer surface. The entire assembly is then covered, in the preferred embodiment, with a metal layer, to hermetically seal the entire chip-on-board assembly.
摘要:
A localized soldering station is described that uses the vapor phase reflow principle. A container has of a medium selected because of the temperature at which it changes to a vapor. A heated conduit maintains the vapor state while conveying the vapor to a work location where a module with a part to be removed or attached by solder connections is supported. A transparent, quartz nozzle confines the vapor to the part and its solder connections and is positioned accurately by a unit that includes a guide light. Vapor will lose its latent heat of vaporization upon contact with the part and its solder connections, causing the solder to reflow and change back to a liquid, which is collected for reuse. When in a standby or ready condition, vapor is conveyed up through a shutoff valve through cooling fins where it changes back to a liquid and returns to the container, avoiding loss.
