2. Solderability - Wikipedia

   en.wikipedia.org/wiki/Solderability

   Solderability when using lead-free alloys can differ significantly from solderability when using lead based alloys. Noble metals may be easy to solder but they have brittle joints. The metals in the good category require a large amount of heat therefore oxidation is an issue. To overcome this a flux is required.

3. Solder alloys - Wikipedia

   For low-temperature soldering of heat-sensitive parts, and for soldering in the vicinity of already soldered joints without their remelting. Sn 43 Pb 43 Bi 14: 144: 163 [11] Pb: No: Bi14. Good fatigue resistance combined with low melting point. Contains phases of tin and lead-bismuth. [13] Useful for step soldering. Sn 46 Pb 46 Bi 8: 120: 167 ...

4. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   An improperly selected or applied flux can cause joint failure. Without flux the joint may not be clean, or may be oxidized, resulting in an unsound joint. For electronic work, flux-core solder wire is generally used, but additional flux may be used from a flux pen or dispensed from a small bottle with a syringe-like needle.

5. Ultrasonic soldering - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_soldering

   Ultrasonic soldering (U/S soldering) is a flux-less soldering process that uses ultrasonic energy, without the need for chemicals to solder materials, such as glass, ceramics, and composites, hard to solder metals and other sensitive components which cannot be soldered using conventional means.

6. Solder - Wikipedia

   en.wikipedia.org/wiki/Solder

   Solder (UK: / ˈ s ɒ l d ə, ˈ s ə ʊ l d ə /; [1] NA: / ˈ s ɒ d ər /) [2] is a fusible metal alloy used to create a permanent bond between metal workpieces. Solder is melted in order to wet the parts of the joint, where it adheres to and connects the pieces after cooling.

7. Fusible alloy - Wikipedia

   en.wikipedia.org/wiki/Fusible_alloy

   Fusible alloys are typically made from low melting metals. There are 14 low melting metallic elements that are stable for practical handling. These are in 2 distinct groups: The 5 alkali metals have 1 s electron and melt between +181 (Li) and +28 (Cs) Celsius; The 9 poor metals have 10 d electrons and from none (Zn, Cd, Hg) to three (Bi) p electrons, they melt between -38 (Hg) and +419 (Zn ...
