摘要： A tin-lead solder alloy containing copper and optionally silver as its alloying constituents. The solder alloy consists essentially of, by weight, about 55% to about 75% tin, about 11% to about 44% lead, up to about 4% silver, nickel, palladium, platinum and/or gold, greater than 1% to about 10% copper, and incidental impurities. The solder alloys contain a small portion of CuSn intermetallic compounds, and exhibit a melting mechanism in which all but the intermetallic compounds melt within a narrow temperature range, though the actual liquidus temperature of the alloys may be considerably higher, such that the alloys can be treated as requiring peak reflow temperatures of about 250° C. or less. The intermetallic compounds precipitate out to form a diffusion barrier that increases the reliability of solder connections formed therewith.

摘要： A tin-lead solder alloy containing copper and/or nickel and optionally silver, palladium, platinum and/or gold as its alloying constituents. The solder alloy consists essentially of, by weight, about 5% to about 70% tin, up to about 4% silver palladium, platinum and/or gold, about 0.5% to about 10% copper and/or nickel, the balance lead and incidental impurities. The presence of copper and/or nickel in the alloy has the beneficial effect of inhibiting the dissolution and leaching of silver from a silver-containing thick-film, such as a conductor or solder pad, into the molten solder alloy during reflow. In addition, solder joints formed of the solder alloy form a diffusion barrier layer of intermetallic compounds that inhibit solid-state interdiffusion between silver from a silver-containing thick-film and tin from the solder joint.

摘要： A fuel injector wherein a cylindrical surface supports an electrical heating structure covering 360° or almost 360° of the surface for heating fuel. The structure comprises a first dielectric layer adhered to the surface; a thick film resistance heating element; a second dielectric layer; spaced-apart first and second conductor pads, wherein the first conductor pad is disposed in contact with a dielectric layer and a first end of the heating element, and wherein the second conductor pad is disposed in contact with a dielectric layer and a second end of the heating element. Another dielectric layer may be disposed over the preceding layers and the first and second conductor pads and having first and second windows formed therein for access to the first and second conductor pads. The resistance heating element may selectively be trimmed by overprinting in a pattern one or more times to improve the uniformity of heating.

摘要： A solder alloy containing indium, lead, silver and copper as its alloying constituents, and a soldering process employing the solder alloy. The solder alloy consists essentially of, by weight, about 50% to about 65% indium, about 0.5% to about 3.0% silver, up to about 3.0% copper, the balance lead and incidental impurities. The alloy preferably has a solidus temperature in a range of about 173° C. to about 178° C., and a liquidus temperature in a range of about 187° C. to about 196° C. As such, the alloy can be used in a reflow process with a peak reflow temperature of about 220° C. to about 240° C., and is therefore compatible with most circuit components and can be simultaneously reflowed with 63Sn-37Pb solder.

摘要： The invention includes the discovery that the addition of a thermosetting polymer to a thick-film conductor formulation including a thermoplastic polymer will substantially retard the spreading of the thick-film conductor ink upon firing of the printed conductor. The thermosetting polymer may be from the family of allylic esters, for example poly(diallyl phthalate). The invention also includes the discovery that the thermosetting resin can be dissolved with an organic solvent to form an additive so as to uniformly distribute the thermosetting polymer within the thick-film conductor formulation including the thermoplastic polymers. Preferred organic solvents include alcohols with a weight ratio of thermoset-to-organic solvent ranging from about 1:1.5 to about 1:3.

摘要： A lead-free solder alloy consisting essentially of, by weight, 3.0% to 3.5% silver, greater than 1% to about 15% copper, the balance tin and incidental impurities, and having an effective melting range of about 215° C. to about 222° C. The solder alloy is noneutectic, and therefore characterized by solidus and liquidus temperatures, the former being in a range of about 215° C. to about 218° C., while the latter is about 290° C. or more. However, the melting mechanism exhibited by the alloy is such that the alloy is substantially all melted and does not exhibit a “mushy zone” above the effective melting range, enabling the alloy to behave similarly to the SnAgCu eutectic alloy.
