Tinning is a process of coating leads or other component parts with solder before making a soldered joint. It is done to ensure that the surfaces to be joined will have a good adhesion to the solder to ensure a robust and secure joint. If leads are not tinned before hand, there is a risk of a dry joint - a joint that might appear to be good but in fact does not have solder in intimate contact with the component. Most dry joints have an appearance that exposes the fault but not all do.
The term tinning is used as tin is a component of solder (traditional solder is a mix of tin and lead). Tinning now usually means applying solder as described above but it can also mean applying a coating of tin without lead. Using pure tin is rarely if ever used today.
Worldwide there is a move to eliminate lead from electronic assemblies and so tin/lead solder is being replaced. Tin is still used but mixed with copper, silver, zing and other more exotic metals. The process of tinning still takes place even with the new lead free solders.
