Description

This is a compilation of the results on the measurements of temperatures by using thermocouples and an infrared camera to test the capacity of Infrared Thermography Nondestructive Methodology to detect solder joint defects in a connector of a particular solenoid coil. Discrimination analyses results, as well as repeatibility analyses results, are given. The ANOVA based discrimination analyses make paired comparisons among the good solder and defective solders, providing a probability of being the same (P) with a 95% confidence interval, as well as the minimum, mean, and maximum differences in excess temperatures encountered. Minimum differences in excess temperature larger than 2 degrees Celsius give a conservative criterion to determine if a defective solder joint can be distinguished from a good solder joint.
