Abstract: An electronic device is disclosed herein. In accordance with certain implementations, the electronic device includes a printed circuit board having electrically conductive traces formed thereon. The electronic device also includes a thermochromic solder mask layer overlying the electrically conductive traces. The thermochromic solder mask layer changes color in response to temperature changes associated with operation of the electronic device. The thermochromic characteristics of the solder mask layer are useful for purposes of indicating overheating of the electronic device, the conductive traces, or a region of the printed circuit board.
