The TLC-100 Kit from Advanced Thermal Solutions features spray-on
thermochromic liquid crystals which change color at different temperatures to
reveal heat issues on chips and other electronic components. By applying these
liquid crystals, engineers can visually find hotspots and temperature fields.
TLC-100 liquid crystals are designed for heat transfer studies and mapping
heat fields on electronic components or boards. The crystals change color at a
specified temperature starting at red, changing to green then blue. For
electronics cooling applications, this provides the user accurate information
about the location of hot spots on a device, their temperature and temperature
To map the temperature profile of a component or board, black ink is
airbrushed on to the specimen. Then TLCs, with a 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 begin turning red, then into different colors, representing the
temperature distribution of the component or board.
Thermochromic liquid crystals are available in a variety of temperature
ranges from 12°C to 120°C, each one has a particular bandwidth from 1°C to 20°C.
Hotspot locations can be confirmed and changing temperatures can be seen at
various current output levels. The TLC-100 crystals can show thermal patterns,
not just at the chip but on the surrounding hardware.
