Solder alloys. Solder is a metallic material that is used to connect metal workpieces. The choice of specific solder alloys depends on their melting point, chemical reactivity, mechanical properties, toxicity, and other properties. Hence a wide range of solder alloys exist, and only major ones are listed below.
A fusible alloy is a metal alloy capable of being easily fused, i.e. easily meltable, at relatively low temperatures. Fusible alloys are commonly, but not necessarily, eutectic alloys. Sometimes the term "fusible alloy" is used to describe alloys with a melting point below 183 °C (361 °F; 456 K). Fusible alloys in this sense are used for solder.
Soldering. Desoldering a contact from a wire. Soldering (US: / ˈsɒdərɪŋ /; UK: / ˈsoʊldərɪŋ /) is a process of joining two metal surfaces together using a filler metal called solder. The soldering process involves heating the surfaces to be joined and melting the solder, which is then allowed to cool and solidify, creating a strong ...
Soft solder typically has a melting point range of 90 to 450 °C (190 to 840 °F; 360 to 720 K), [3] and is commonly used in electronics, plumbing, and sheet metal work. Alloys that melt between 180 and 190 °C (360 and 370 °F; 450 and 460 K) are the most commonly used.
A desoldering pump, colloquially known as a solder sucker, is a manually-operated device which is used to remove solder from a printed circuit board. There are two types: the plunger style and bulb style. [1] (. An electrically-operated pump for this purpose would usually be called a vacuum pump.)
Cerrosafe. Cerrosafe is a fusible alloy with a low melting point. It is a non- eutectic mixture consisting of 42.5% bismuth, 37.7% lead, 11.3% tin, and 8.5% cadmium that melts between 70 °C (158 °F) and 88 °C (190 °F). It is useful for making reference castings whose dimensions can be correlated to those of the mold or other template due to ...
