Abstract
Components are connected together in circuits by soldered joints. Solder is basically an alloy of lead and tin, the proportions varying according to the application. For electronics work a mixture of 60 per cent tin and 40 per cent lead is usual. If solder is heated to its melting point, and applied to a variety of different metals, it will amalgamate with the metal surface to provide a joint with high electrical conductivity and good mechanical strength—the strength is limited by the relatively poor tensile strength of the solder itself. Solder has a low melting point, lower than that of either tin or lead. The melting point varies according to the exact composition of the solder, but ordinary 60/40 tin/lead solder melts at 188°C.
