To map the temperature profile of a component or board, black ink is airbrushed on to the specimen. Then, TLCs with a particular temperature range (depending on the application), are sprayed onto the measurement surface. Once the device is turned on and the components are brought to activation temperature, the liquid crystals will begin turning red, then into different colors, representing the temperature distribution of the component or board. Black ink and TLCs are non-destructive and wash off with soap and water. Thermochromic liquid crystals from Advanced Thermal Solutions are available in various temperature ranges from +20°C to +120°C, each with a particular bandwidth from 1 to +20°C.
