Abstract
A circuit board capable of indicating the temperature of hot elements thereon is disclosed. The circuit board includes a substrate, a hot element and a thermochromic material. The hot element may be a chip set or a CPU. The thermochromic material may be inorganic thermochromic materials, or organic thermochromic materials, such as polymers, liquid crystals, dyes, or combinations thereof.
Claims15
A circuit board, comprising:
- a substrate;
- a heat-generating element, assembled on the substrate;
- and
- a thermochromic material, which changes color according to a pre-determined temperature and at least partially covers a surface of the heat-generating element to indicate a temperature condition of the heat-generating element.
