    摘要: A primary lithium battery particularly adapted for use in self-contained self-powered devices (SSPD) for mobile communication and computing products, such as radio frequency identification tags, PCMCIA cards, and smart cards. The battery has a flexible and compact design, and utilizes a solid polymer electrolyte membrane that preferably has a polyacrylonitrile matrix. Performance of the electrolyte membrane is optimized by controlling the amount of aprotic organic solvents within the membrane within a prescribed range of ratios. In so doing, the performance characteristics of the battery closely approximate that of conventional liquid electrolytes without the safety hazards associated with the risk of liquid electrolyte leakage, and exhibit enhanced performance at sub-ambient temperatures. A further feature is that the battery's cathode is encapsulated within a polymeric matrix that eliminates the exposure hazard posed by lithium intercalation compounds used within the cathode.

    摘要: A tool and process for electroetching metal films or layers on a substrate employs a linear electrode and a linear jet of electrolyte squirted from the electrode. The electrode is slowly scanned over the film by a drive mechanism. The current is preferably intermittent. In one embodiment a single wafer surface (substrate) is inverted and the jet is scanned underneath. In another embodiment wafers are held vertically on opposite sides of a holder and two linear electrodes, oriented horizontally and on opposite sides of the holder, are scanned vertically upward at a rate such that the metal layers are completely removed in one pass. The process is especially adapted for fabricating C4 solder balls with triple seed layers of Ti-W (titanium-tungsten alloy) on a substrate, phased Cr-Cu consisting of 50% chromium (Cr) and 50% copper (Cu), and substantially pure Cu. Solder alloys are through-mask electrodeposited on the Cu layer. The seed layers conduct the plating current. During etching the seed layers are removed between the solder bumps to isolate them. The phased Cr-Cu and Cu layers are removed by a single electroetching operation in aqueous potassium sulfate and glycerol with cell voltage set to dissolve the phased layer more quickly than the Cu, avoiding excessive solder bump undercutting in the copper layer. The cell voltage may be such that the solder bump is only slightly undercut so as to form a stepped base C4 structure upon reflowing. Ti-W is removed by a chemical process.

The battery utilizes a solid polymer electrolyte membrane that preferably has a polyacrylonitrile matrix. Performance of the electrolyte membrane is optimized by controlling the amount of aprotic organic solvents within the membrane within a prescribed range of ratios. The battery cathode is encapsulated within a polymeric matrix that eliminates the exposure hazard posed by lithium intercalation compounds used within the cathode. Use of stainless steel foil current collectors gives a high open circuit voltage of 3.8 volts and high cell capacity. A method of determining the optimum cathode thickness in the battery is also described. This provides a means of maximizing volumetric and gravimetric energy densities by using the optimum amount of cathode material. Batteries fabricated by using optimal materials can be operated under pulsed and dc discharge conditions over a temperature range between about -40 and +80.degree. C.

    摘要: A primary lithium battery particularly adapted for use in self-contained self-powered devices (SSPD) for mobile communication and computing products, such as radio frequency identification tags, PCMCIA cards, and smart cards. The battery has a flexible and compact design which eliminates use of a separate electrolyte membrane by utilizing an electrolyte-bearing composite cathode that preferably has a polyacrylonitrile matrix. Performance of the battery is optimized by controlling the amount of aprotic organic solvents within the composite cathode within a prescribed range of ratios. In so doing, the performance characteristics of the battery closely approximate those having conventional liquid electrolytes without the safety concerns associated with liquid electrolyte leakage, and exhibit enhanced performance at sub-ambient temperatures. A further feature is that the composite cathode is encapsulated within a polymeric matrix that eliminates the exposure hazard posed by the lithium intercalation compounds used within the cathode. The battery is enclosed in a customized laminate stack for sealing and encapsulation. Alternative packaging embodiments are also disclosed.

    摘要: A heat exchanging system uses a metallic TIM for efficient heat transfer between a heat source and a heat exchanger. The heat source is preferably an integrated circuit coupled to a circuit board. The metallic TIM preferably comprises indium. The metallic TIM is comprised of either a separate metallic TIM foil or as a deposited layer of metal material. The metallic TIM foil is mechanically joined to a first surface of the heat exchanger and to a first surface of the integrated circuit by applying sufficient pressure during clamping. Disassembly is accomplished by un-clamping the heat exchanger, the metallic TIM foil, and the integrated circuit from each other. Once disassembled, the heat exchanger and the metallic TIM foil are available to be used again. If the metallic TIM is deposited onto the heat exchanger, disassembly yields a heat exchanging sub-assembly that is also reusable.
