2. 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. [2]

3. Solderability - Wikipedia

   en.wikipedia.org/wiki/Solderability

   Both quantitative and qualitative tests for solderability exist. [6] The two most common testing methods are the 'dip and look' method and wetting balance analysis.In both of these tests, the soldered pieces undergo an accelerated aging process before being tested for solderability, to take into consideration the time a component was in storage prior to mounting to final assembly.

4. Solder paste - Wikipedia

   en.wikipedia.org/wiki/Solder_paste

   Solder paste is used in the manufacture of printed circuit boards to connect surface mount components to pads on the board. It is also possible to solder through-hole pin in paste components by printing solder paste in and over the holes. The sticky paste temporarily holds components in place; the board is then heated, melting the paste and ...

   The result is iFixit’s soldering iron powered by USB-C. It features a heat-resistant cap, like a pen, to reduce burn risk, and an accelerometer to automatically switch it off if you drop it.

6. Solder alloys - Wikipedia

   en.wikipedia.org/wiki/Solder_alloys

   Soldering copper pipes using a propane torch and a lead-free solder. 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 ...

7. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   Each solder alloy has characteristics that work best for certain applications, notably strength and conductivity, and each type of solder and alloy has different melting temperatures. The term silver solder denotes the type of solder that is used. Some soft solders are "silver-bearing" alloys used to solder silver-plated items.
