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

   en.wikipedia.org/wiki/Solder_alloys

   Copper content increases hardness of the alloy and inhibits dissolution of soldering iron tips and part leads in molten solder. Sn 62 Pb 37 Cu 1: 183 [17] Pb: Yes: Similar to Sn 63 Pb 37. Copper content increases hardness of the alloy and inhibits dissolution of soldering iron tips and part leads in molten solder. Sn 63 Pb 37 P 0.0015-0.04: 183 ...

4. Tin-silver-copper - Wikipedia

   en.wikipedia.org/wiki/Tin-silver-copper

   Tin-silver-copper (Sn-Ag-Cu, also known as SAC), is a lead-free alloy commonly used for electronic solder.It is the main choice for lead-free surface-mount technology (SMT) assembly in the industry, [1] as it is near eutectic, with adequate thermal fatigue properties, strength, and wettability.

5. Soldering iron - Wikipedia

   en.wikipedia.org/wiki/Soldering_iron

   A soldering station has a temperature control and consists of an electrical power supply, control circuitry with provision for user adjustment of temperature and display, and a soldering iron or soldering head with a tip temperature sensor. The station will normally have a stand for the hot iron when not in use, and a wet sponge for cleaning.

6. Dip soldering - Wikipedia

   en.wikipedia.org/wiki/Dip_soldering

   The most common dip soldering operations use zinc-aluminum and tin-lead solders. Solder pot metal: cast iron or steel, electrically heated. Bath temperature: 220 to 260 °C (for binary tin-lead alloys) or 350 to 400 °C (for lead-free alloys) Solder composition: 60% Sn, 40% Pb or eutectic alloy.

7. Whisker (metallurgy) - Wikipedia

   en.wikipedia.org/wiki/Whisker_(metallurgy)

   Metal whiskering is a phenomenon that occurs in electrical devices when metals form long whisker-like projections over time. Tin whiskers were noticed and documented in the vacuum tube era of electronics early in the 20th century in equipment that used pure, or almost pure, tin solder in their production.
