What is the composition of solder?
What is the composition of solder?
The solder composition, being free of lead and other known toxic metals, has a composition range of 0.5-4.0% antimony, 0.5-4.0% zinc, 0.1-3.0% silver, 0.1-2.0% copper and 86.8-98.8% tin, is especially adaptable for plumbing applications where solder joints are exposed to potable water.
What is lead-free solder composition?
Lead-free solder formulations have a varied percentage of metals. Components can include tin, copper, silver, nickel and zinc. The most common lead-free mix is tin-copper, which has a melting point of 217°C.
What is lead-free solder used for?
Lead-free solders have been increasing in use due to regulatory requirements plus the health and environmental benefits of avoiding lead-based electronic components. They are almost exclusively used today in consumer electronics.
What is SN100C solder?
DESCRIPTION. SN100C is a lead-free silver-free solder alloy developed by Nihon Superior in Japan. SN100C offers user-friendly properties and has been proven in commercial applications since 1999. The inclusion of nickel reduces copper dissolution and produces a bright shiny solder fillet.

What is the difference between leaded and lead-free solder?
Lead-Free vs. Lead-free solder has a higher melting point at 217°C compared to 183°C for lead alloys. This makes lead-free solder more challenging to work with. The most common lead-free solder mix is tin-copper, which has a melting point of 217°C and mixes 99.3% tin with 0.7% copper.
What is the difference between lead and lead-free solder?
Lead is harmful to the environment and is toxic to the body with the additional hazard of being so quickly absorbed into the bloodstream. Lead-free solder paste will melt at higher temperatures of around about 422°F.
What is soldering PDF?
Soldering is a process used for joining metal parts to form a mechanical or electrical bond. It typically uses a low melting point metal alloy (solder) which is melted and applied to the metal parts to be joined and this bonds to the metal parts and forms a connection when the solder solidifies.
