Abstract
A method of manufacturing a power module on a substrate. In one embodiment, the method includes providing power conversion circuitry including providing a magnetic device having a magnetic core and at least one switch on the substrate. The method also includes placing a shielding structure over the magnetic core to create a chamber thereabout. The method also includes depositing an encapsulant about the power conversion circuitry. The shielding structure limits the encapsulant entering the chamber thereby allowing the encapsulant to surround a portion of the magnetic core within the chamber.
Claims10
A method of manufacturing a power module on a substrate, comprising:
- providing power conversion circuitry, including:
- providing a magnetic device having a magnetic core with a lower surface thereof located on said substrate,
- placing a shielding structure over an upper surface of said magnetic core and about a portion of opposing sides of said magnetic core to create a chamber thereabout, and
- providing at least one switch on said substrate;
- and
- depositing an encapsulant about said power conversion circuitry, said shielding structure limiting said encapsulant entering said chamber thereby limiting an amount of said encapsulant that contacts said magnetic core within said chamber by directing said encapsulant about said shielding structure to enter said chamber via an opening formed between said shielding structure and said substrate on at least one side of said magnetic core.
