Engineers have developed solder pastes, adhesives, and assembly processes that permit attaching inductor terminals to PCBs without using holes. Flat areas (known as pads) on the inductor terminals are soldered directly to copper circuitry surfaces hence the term surface mount inductor (or transformer). This process eliminates the need to drill holes for the pins, thereby reducing the cost to manufacture a PCB.
