Surface Mount Vs. Thru-Hole

Most chips are surface mounted to the circuit board, but some are thru-hole, in which the pins go through the board and are soldered underneath. With surface mounted chips and no holes drilled through the board, the real estate under the device can be used by the circuit board designer for other board layers.

Gull-Wing Surface Mounts

These are examples of the common gull-wing style of leads on surface mount chips. The leads extend slightly out from the package, then down and out again.

Discrete and Surface Mounted

Although most discrete resistors are thru-hole devices, these resistors are surface mounted to save space as well as time making the board.
