Self-healing PDMS encapsulation and repair of power modules

A self-healing power module assembly with double sided cooling, the self-healing power module assembly comprising:

• a lower electrode;
• a semiconductor electronics device coupled to the lower electrode;
• a spacer component adjacent the semiconductor electronics device;
• an upper electrode disposed adjacent to the spacer component;
• a frame component cooperating with the upper electrode and the lower electrode to define an enclosure containing the semiconductor electronics device and the spacer component, the frame component comprising a resin with at least one heat transfer component embedded within the frame component and in direct thermal communication with one of the upper and lower electrodes, such that the frame component is configured to confine waste heat to edge regions of the semiconductor electronics device;
• and
• a self-healing polymer comprising disulfide bonds, the self-healing polymer disposed within the enclosure.

A power electronics assembly with a self-healing feature, the power electronics assembly comprising:

• a semiconductor electronics device;
• an insulating substrate coupled to the semiconductor electronics device;
• a base metal structural component coupled to the insulating substrate;
• a frame component cooperating with the base metal structural component and including interior walls defining an enclosure containing the semiconductor electronics device and the insulating substrate;
• at least one heat transfer component embedded within the frame component and to in direct thermal communication with the base metal structural component to increase a temperature of the frame component;
• at least one terminal providing an external connection;
• and
• a self-healing polymer comprising disulfide bonds, the self-healing polymer disposed within the enclosure and adjacent the interior walls, wherein the interior walls of the frame component are configured to confine waste heat to edge regions of the semiconductor electronics device.
