2. 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 ...

3. 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 ]

4. 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 ...

   Lead Free Mama, LLC, tested the 32 ounce Hydroflask in 2017 and deemed it lead free, and more recently added the bottle to a 2023 round up of favorite lead-free water bottles. Owala. Owala took to ...

6. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   Additionally, tin is a more corrosive metal, and can eventually lead to the failure of solder baths [clarification needed]. [36] Lead-free construction has also extended to components, pins, and connectors. Most of these pins used copper frames, and either lead, tin, gold or other finishes. Tin finishes are the most popular of lead-free finishes.

7. RoHS - Wikipedia

   en.wikipedia.org/wiki/RoHS

   The more common lead-free solder systems have a higher melting point, e.g. a 30 °C typical difference for tin-silver-copper alloys, but wave soldering temperatures are approximately the same at ~255 °C; [47] however at this temperature most typical lead-free solders have longer wetting times than eutectic Pb/Sn 37:63 solder.
