The standard test circuit board consists of a four layer FR4 material with 2 ounce (70µm) outer layers and 1 ounce
(35µm) inner layers, which is typical of many industry designs. The test conditions were in ambient temperature
conditions, approximately 22 °C with no forced air. Contact TT electronics for more details or for other thermal image
test data for specific resistance values and power levels.
