    摘要: There is disclosed herein a self-shearing stencil for use in applying solder paste or other bonding material atop a printed circuit board (PCB) in a predefined pattern. The stencil 50 has a top surface 12, a bottom surface 14, a first surface cavity 16 in the top surface, and a second surface cavity 18 in the bottom surface proximate the first surface. The cavities 16/18 overlap in a predefined manner so as to be in open communication with each other. When the stencil is placed on the PCB, the cavities are filled with solder paste and the PCB is then lowered away from the stencil, whereupon a bottom ledge 26 (defined by the stencil material underneath the first cavity) shears off the solder paste in the first cavity from the paste in the second cavity.

    摘要: Flatwire assembly having a number of conductive elements or traces position on the substrate of the flatwire. In order to protect the conductive element from environmental hazards such as moisture and chemicals, a sealing film is provided that encapsulates the conductive elements. The sealing film has a polymer layer and an adhesive layer. The polymer layer prevents vertical diffusion of moisture into the conductive elements and the adhesive layer prevents later diffusion of moisture. The sealing film is larger than the conductive elements such that it completely encapsulates the conductive elements.

    摘要: Positioning of sensitive electronics near the engine block is accomplished through the use of a heat shield providing for removal or diversion of transmitted heat from the block to the electronics through the use of a self-contained or externally circulated coolant fluid. Unlike conventional coolant channels in an engine block, the heat shield is not intended to cool the engine block and thus may be more compact insofar as it deals with lesser heat flux.

    摘要: 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.
