Solder

maker

Solder is an alloy used to join metal components, typically in electronic circuit assembly.

expanded

Solder is a fusible metal alloy used to create a permanent bond between metal workpieces. It is crucial in electronics for mounting components to printed circuit boards (PCBs) due to its ability to form reliable electrical and mechanical connections.

examples

Lead-free solder composed of tin-copper alloy, with a melting temperature of approximately 227 °C (440 °F).

Commonly used in consumer electronics assembly to comply with environmental regulations like RoHS.

60/40 lead-tin solder, with a melting point of around 183 °C (361 °F).

Widely used in traditional through-hole component soldering in DIY electronics projects.
