The new ethermVIEW liquid crystal thermographic analysis system provides optical temperature measurements of active PCBs and components. The system uses the color response of thermochromic liquid crystals (TLC) for non-invasive thermal studies. Developed by Advanced Thermal Solutions, Inc., the system includes a high performance, solid-state color camera for macroscopic inspection of boards and components coated with heat-sensitive liquid crystals. The camera features a flicker-free white light source for clear viewing of dark surfaces and partially concealed features. It links to a PC by Firewire, the standard connection for high definition video devices. For image processing and management, the system includes proprietary thermSOFT software, and a transformer is provided for international use. Liquid crystals used with ethermVIEW reflect incident light at visible wavelengths based on the surfaces temperatures where they’re applied. The camera captures the reactive TLC colors to reveal hot spots and defects for more effective thermal management. In contrast to infrared thermography systems, the ethermVIEW TLC method is not affected by ambient temperatures. It provides more precise temperature measurements – within +/- 0.1°C accuracy.
