Patent ID: 7698808

Claim:
A method of making surface-mount coil packages, comprising: (a) providing at least two circuit board units connected in a plane, each of which has at least one group of wiring patterns fabricated on the at least two circuit board; (b) mounting a coil bobbin on at least some of the at least two circuit board units; (c) winding a single line of conductive wire around the coil bobbin mounted on one of the at least two circuit board units; (d) extending the line of conductive wire continuous from the coil bobbin to a neighboring coil bobbin mounted on another one of the at least two circuit board units; (e) repeating steps (c) and (d) to successively wind the line of conductive wire around one coil bobbin to a neighboring bobbin; and (f) separating the at least two circuit board units after a necessary number of coil bobbins are wound with the line of conductive wire.
