FORMULA:-
Examples of these four-element compositions are 18/64/14/4 tin-silver-copper-zinc (melting range 217–220 °C)
and 18/64/16/2 tin-silver-copper-manganese (Sn-Ag-Cu-Mn; melting range of 211–215 °C)
Types of solder
Lead-Based Solder. Lead solder, made of lead and tin, is used for most electronic manufacturing applications to
form a strong bond between the joints of other metals, such as copper and aluminium.
Lead-Free Solder. Lead-free solder generally has a higher melting point than conventional solder.
