Thermal module for a circuit board

A circuit board assembly comprising:

• a circuit board;
• a standoff coupled to the circuit board, the standoff comprising:
• a receiving surface, and
• a first extension and a second extension, wherein the first extension and the second extension extend from the receiving surface;
• and
• a thermal module that covers the receiving surface, the thermal module comprising:
• a non-metal layer,
• an electrical insulator, and
• a metal layer positioned between the non-metal layer and the electrical insulator.

A portable electronic device comprising:

• a display housing that carries a display;
• and
• a base portion rotationally coupled with the display housing, the base portion comprising:
• a circuit board that carries a heat-generating component, the circuit board comprising a perimeter;
• a standoff disposed on the perimeter of the circuit board, the standoff comprises a first extension, a second extension, and an opening between the first extension and the second extension;
• and
• a thermal module mechanically coupled with the standoff, the thermal module comprising:
• a metal layer in contact with the standoff, the metal layer comprising a protruding element positioned in the opening,
• a first portion that covers the heat-generating component, and
• a second portion that extends laterally beyond the standoff.

An electronic device comprising:

• a housing that includes an internal chamber;
• and
• components located in the internal chamber, the components comprising:
• a circuit board that carries a heat-generating component;
• a metal standoff disposed on a perimeter of the circuit board, the metal standoff comprising an opening;
• and
• a thermal module mechanically coupled with the metal standoff, the thermal module comprising:
• a metal layer comprising a protruding element positioned in the opening, wherein the metal layer comprises an embossed region,
• a non-metal layer disposed on the embossed region,
• a first portion that covers the heat-generating component, and
• a second portion that extends laterally beyond the metal standoff.
