On gold surfaces gold-indium intermetallics tend to be formed, and the joint then fails in the gold-depleted zone and the gold-rich intermetallic. [37] Less gold dissolution and more ductile than lead-tin alloys. [12] Good thermal fatigue properties. Pb 60 In 40: 195: 225 [16] Pb: No: In40. Low gold-leaching. Good thermal fatigue properties. Pb ...
Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...
1×6 pin header (one row) 1×6 female header (one row) A pin header (or simply, header) is a form of electrical connector.A male pin header consists of one or more rows of metal pins molded into a plastic base, often 2.54 mm (0.1 in) apart, though available in many spacings. [1]
Where components are to be placed, the printed circuit board normally has flat, usually tin-lead, silver, or gold plated copper pads without holes, called solder pads. Solder paste, a sticky mixture of flux and tiny solder particles, is first applied to all the solder pads with a stainless steel or nickel stencil using a screen printing process.
Menard, Inc., doing business as Menards, (/ m ə ˈ n ɑːr d z / mə-NARDZ) is an American big-box home improvement retail chain headquartered in Eau Claire, Wisconsin. It is the third-largest home improvement retailer in the United States (behind Lowe's and Home Depot ), with 351 stores in 15 U.S. states, primarily in the Midwest . [ 1 ]
Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
Hot tin-dipping is the process of immersing a part into a bath of pure molten tin at a temperature greater than 450 °F or 232 °C. Tinplate made via hot-dipped tin plating is made by cold rolling steel or iron, pickling to remove any scale, annealing to remove any strain hardening, and then coating it with a thin layer of tin.
Metal whiskering is a crystalline metallurgical phenomenon involving the spontaneous growth of tiny, filiform hairs from a metallic surface. The effect is primarily seen on elemental metals but also occurs with alloys. The mechanism behind metal whisker growth is not well understood, but seems to be encouraged by compressive mechanical stresses ...
