Solders
Solder is a fusible metal alloy used to join two metal surfaces by melting at a temperature lower than the base metals. When the filler metal flows into the joint and cools, it forms a mechanical and electrical connection. Soldering is commonly used in electronics, plumbing, metalworking, and jewelry.
There are two broad categories: soft solders and hard solders. Soft solders melt well below 300°C and
Hard solders have higher melting ranges and include silver solder and other alloys used for jewelry, copper
Flux plays a key role by removing oxides from surfaces to improve wetting and flow of the
Applications and considerations: solder joints should wet the surfaces well for a strong bond. Poor wetting
