摘要:
An electronic module containing a heat sink member, a flexible printed circuit board with electrical components mounted on both sides, and a protective cover. The heat sink member has an external surface containing a plurality of protruding fins. Its internal surface contains a raised grid of ribs with cavities present between the ribs. The cavities contain ceramic-filled silicone for improved heat transfer between the electrical components present on the circuit board, and the heat sink member. High heat-producing components are mounted on one side of the circuit board and are thermally coupled with the heat sink member by means of copper-plated through-holes in the circuit board. The protective cover is mounted to the internal surface of the heat sink and encloses the printed circuit board. A connector assembly serves to connect the electronic module to external circuitry.

Central mounting of control electronics proximate to the engine is provided by attaching the electronics to an upper surface of the intake manifold to provide heat shielding and heat conduction for active components on the circuit card. The central location provides extremely short harnesses to important actuators located in cylinder heads of the engine thus reducing wiring clutter and cost.

Disclosed herein is a method and apparatus for splicing flexible circuit boards, particularly those having one or more flexible strip extensions with conductor runs. The splice clamp of the present invention has two hinged plates that clamp over unconnected ends of two flexible circuit board segments. The splice clamp includes alignment guides for aligning the segments in the clamp so that one or more jumpers contact and provide an electrical bridge between the conductors of the segments when the plates are clamped together. The jumpers contact conductive pads of larger size than the conductor runs to ensure electrical coupling between the flexible circuit board segments. The jumpers may have pointed tips that cut through insulation. The clamp includes flexible clasps on one plate that engage with catch surfaces on the other plate to lock the flexible circuit board segments spliced together.
