An SMT component is usually smaller than its through-hole counterpart because it has either smaller leads or no leads at all. It may have short pins or leads of various styles, flat contacts, a matrix of solder balls (BGAs), or terminations on the body of the component.

The main advantages of SMT over the older through-hole technique are:

1. Smaller components.

2. Much higher component density (components per unit area) and many more connections per component.

3. Components can be placed on both sides of the circuit board.

4. Higher density of connections because holes do not block routing space on inner layers, nor on back-side layers if components are mounted on only one side of the PCB.
