Coil Inductor Assembly Method
This technology-plastic deformation magnetic assembly (PDMA)-is an innovative, proven, patent-pending method for vertically assembling inexpensive, high-performance coil inductors that take up a small area on the chip and reduce noise due to substrate loss. University researchers developed this novel assembly method for integrating coil inductors into radio frequency (RF) circuits. PDMA essentially stands the coil inductors vertically on end so that they take up far less space on the chip than planar inductors. This three-dimensional (3D) assembly method yields several advantages for the coil inductors themselves and consequently for the products that use them. The technique also can be used to improve other devices such as sensors.
