When to use a terminal pin?
Yes, wire-to-board connections are often made with a variety of terminal pins in order to increase their mechanical strength, current carrying capability and optimise form factor.

The most common terminals used are turrets and solder cups. Turrets allow a wire to be hooked around it at a right angle to the terminal. Solder cups allow wire mounting to be vertical. Both have their place in designs.

There is a solder specification for these types of connections, IPC-A-610. There are images of these terminals in the document, which I will not link to but can be found on google.
