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.

3. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   The solder used in the process can vary in composition, with different alloys used for different applications. Common solder alloys include tin-lead, tin-silver, and tin-copper, among others. Lead-free solder has also become more widely used in recent years due to health and environmental concerns associated with the use of lead.

4. 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.

5. Soldering iron - Wikipedia

   en.wikipedia.org/wiki/Soldering_iron

   When the iron tip oxidises and burnt flux accumulates on it, solder no longer wets the tip, impeding heat transfer and making soldering difficult or impossible; tips must be periodically cleaned in use. Such problems happen with all kinds of solder, but are much more severe with the lead-free solders which have become widespread in electronics ...

6. Solder - Wikipedia

   en.wikipedia.org/wiki/Solder

   When lead-free solder is used in wave soldering, a slightly modified solder pot may be desirable (e.g. titanium liners or impellers) to reduce maintenance cost due to increased tin-scavenging of high-tin solder. Lead-free solder is prohibited in critical applications, such as aerospace, military and medical projects, because joints are likely ...
