Abstract:
An electronic component temperature monitoring system is provided for monitoring the temperature of electrical and electronic components and integrated circuit. This system, in one embodiment of the invention can consist of a temperature indicating decalcomania attached to the electrical and/or electronic component to be monitored. The decalcomania consists of a layer of nematic crystal material which as the time of manufacture is a milky substance. When the material is applied to a surface and let to dry, it becomes transparent and virtually undetectable. When the material is attahced to a electrical and/or electronic component, the crystal material reaches a set temperature, and becomes opaque in appearance and changes color with the fluctuation in temperature. The material is sandwiched between mylar, with a layer of adhesive opaque material is applied to the lower surface of the decalcomania. The combined layers are then cut into small sections.
