Color-Changing Thermochromic Liquid Crystals from ATS
Norwood, MA — Thermochromic liquid crystals available from Advanced Thermal Solutions can be sprayed on. The liquid crystals change color at dif- ferent 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 elec- tronic components or boards. The crystals change color at a specified temperature starting at red, changing to green then blue. For electronics cool- ing applications, this provides the user accurate information about the location of hot spots on a de- vice, their temperature and temperature gradient.
To map the temperature profile of a compo-
nent 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 temper- ature distribution of the component or board. Thermochromic liquid crystals are available
Liquid crystals change color with temperature.

in a variety of temperature ranges from 12 to 120°C, each one has a particular bandwidth from 1 to 20°C. Hotspot locations can be confirmed and changing temperatures can be seen at various cur- rent output levels. The crystals can show thermal patterns, not just at the chip but on the surrounding hardware. ATS thermal engineers can pro- vide application and interpretation

Polyonics: Colored Poly- imide Labels for Barcodes and PCBs
Westmoreland, NH — Using colored labels to quickly identify parts on mass production runs helps to man- age inventory and save time and money. Polyonics has developed a se- ries of colored polyimide labels for manufacturers who want to color code production/process lines. These labels survive lead-free wave solder- ing processes on the top and bottom side of the board. The colored poly- imide labels are coated with an ag-
