Latest Patents

One of Waseem's latest patents is a method for making magnetic and electromagnetic circuit components. This invention includes an embedded magnetic material, such as ferromagnetic, in a high-density interconnect (HDI) structure with alternating dielectric and metal or winding layers. The ferromagnetic material can be situated in a substrate well or cavity, with or without an adhesive. Additionally, the material can be co-fired with the ceramic substrate and then machined to achieve the desired core shape. An electroplating process is utilized to construct the metal layers, which may include differential plating for varying thicknesses. Laser ablation or other suitable techniques are employed to create through-holes for the insertion of posts of a ferromagnetic core plate, if necessary. This innovative design allows for magnetic or electromagnetic components with a height of less than about 0.1 inch, enabling very low inductance interconnections between these components and other circuit elements.

Another significant patent focuses on high frequency, high density, low profile magnetic circuit components. This invention features a magnetic core with a first and second magnetic layer, with a conductive layer deposited in between. Each magnetic layer is a multilayer structure comprised of alternating magnetic and insulating films. The anisotropic magnetic films are driven along their magnetic hard axis to reduce excess eddy current losses. A distributed air gap is structured in the magnetic layers to minimize eddy current losses in the conductive layer. The conductive layer is patterned on an insulating substrate and extends beyond the peripheries of the magnetic layers, maximizing the amount of magnetic material driven in the hard axis.
