MODULE DE DISPOSITIF A SEMI-CONDUCTEUR

摘要

A flexible power assembly (FPA) provides a new packaging concept suitable for motor control and other functions. An insulated metal substrate (IMS) supports power semiconductor devices and is mounted directly on a heatsink, which supports a circuit board that is mounted above and spaced from the top side of the IMS. There are provided devices that are mounted on the circuit board which are electrically connected to the power semiconductor devices. There may be a cavity in the circuit board allowing the top of the IMS to be exposed, and optionally providing access for bonding wires to the top of the circuit. Bonding pads may be provided on the circuit board for electrical connection with the bonding wires. A cover may be optionally provided to enclose a space over the cavity. Potting compound may be contained in the space created by the cavity.
