1. A method of burn-in testing an electronic device, comprising:
attaching the device to a burn-in board;
placing a first thermally conductive sheet atop the device such that the thermally conductive sheet contacts the device;
placing a second thermally conductive sheet beneath the burn-in board and separated therefrom by an electrically insulating but thermally conductive sheet;
inserting the burn-in board with the device and the thermally conductive sheets into a chamber, wherein the environment within the chamber is controllable;
applying current to the device; and
controlling the environment within the chamber.
