Soldering (US: / ˈ s ɒ d ər ɪ ŋ /; UK: / ˈ s oʊ l d ər ɪ ŋ /) 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 and durable joint.
Like other fusible alloys, e.g. Rose's metal, Wood's metal can be used as a heat-transfer medium in hot baths. Hot baths with Rose's and Wood's metals are not used routinely but are employed at temperatures above 220 °C (428 °F). [7] At room temperature, Wood's metal has a modulus of elasticity of 12.7 GPa and a yield strength of 26.2 MPa. [8]
Soldering irons are designed to reach a temperature range of 200 to 480 °C (392 to 896 °F). [1] Soldering irons are most often used for installation, repairs, and limited production work in electronics assembly. High-volume production lines use other soldering methods. [2] Large irons may be used for soldering joints in sheet metal objects.
Eutectic bonding, also referred to as eutectic soldering, describes a wafer bonding technique with an intermediate metal layer that can produce a eutectic system. Those eutectic metals are alloys that transform directly from solid to liquid state, or vice versa from liquid to solid state, at a specific composition and temperature without ...
Ultrasonic soldering iron tips can heat (up to 450 °C) while mechanically oscillating at 20—60 kHz. This soldering tip can melt solder filler metals as acoustic vibrations are induced in the molten solder pool. The vibration and cavitation in the molten solder then permits solders to wet and adhere to many metal surfaces.
The solder grade used for leadworking is plumber's solder (80% lead / 20% tin). [ i ] Although this is thought of as a high melting point solder amongst lead-tin solders, the solidus is relatively constant for all of these solders and it is the liquidus which climbs from the eutectic point at Sn 63% / Pb 37%.
The SAE discussed an increased automobile standard voltage as early as 1988. [3]In 1994, at the initiative of Daimler-Benz, the first "Workshop on Advanced Architectures for Automotive Electrical Distribution Systems" was held at the Massachusetts Institute of Technology Laboratory for Electromagnetic and Electronic Systems (MIT/LEES) in Cambridge, Massachusetts USA. with the aim of defining ...
