The new ATS ethermVIEW liquid crystal thermographic analysis system provides
optical temperature measurements of active PCBs and components by the color response of thermochromic liquid crystals.
Developed by Advanced Thermal Solutions, Inc., the ethermVIEW system includes
a solid-state color camera for macroscopic inspection of
boards and components coated with heat-sensitive liquid crystals. Starting price for the ethermVIEW thermographic analysis system is US $15,000.
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. The ethermVIEW system can also be
purchased for less than one third the cost of a typical IR thermography system.
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 system includes thermSOFT software used in other ATS thermal analysis devices, for image processing
ATS provides a choice of TLC-100 liquid crystals formulated to respond
visually to specific temperatures. TLC-100 crystals are specifically designed
for mapping heat fields on PCBs and components. The crystals change color at a
specified temperature starting at red, changing to green then blue. The
ethermVIEW system can also be calibrated to use any standard thermochromic
liquid crystals. ATS provides four calibrations at no cost during the first year
of ownership of an ethermVIEW system.
