Inductor Chip

This inductor chip is fabricated without difficulty and provides precise electrical parameters and is suitable for integrated circuit modules of the type described in Integrated Circuit Modules and Core Planes in this issue.

The inductor has an insulating member 20 upon which is deposited along surface 22 a plurality of angularly disposed metal strips 24. These have ball type terminals 26 and 27 at each end. Member 20 is disposed in a cavity 28 located in printed circuit board or insulating member 30. Terminals 26 and 27 extend above the surface of the insulating member. The surface of board 30 is covered with a lacquer film 32. The height of film 32 exceeds that of terminals 26 and 27. Thereafter, the lacquer surface is lapped or reduced in height to expose a cross- sectional area 33 of each terminal 26 and 27. Metallic strips 34 are adhered to the surface of the lacquer film so as to interconnect opposite terminals of adjacent strips 24. The interconnections establish a coil which has a predetermined inductance.

The inductance is fabricated by mass production techniques.
