Question

An alloy solder is used in electronic industry to join different electronic components. What are the constituents of solder?

Answer 1

A homogenous mixture of metal with another metal or a nonmetal results in the formation of alloy.

Solder is used for soldering purposes and it has a low melting point.

• The alloy solder constitutes Lead and Tin.
• In solder, the composition of Lead and Tin is 50% and 50% respectively.

Therefore, the constituents of solder are Lead $\left(\mathrm{Pb}\right)$ and Tin $\left(\mathrm{Sn}\right)$.
