Perhaps this would be a good opportunity to establish the temperature range and
accuracy which is generally required for IR reflow profiling. Temperature
stickers, crayons, etc are available from a number of suppliers, but what
range is needed?
What is lowest temperature needed to be sensed?
What is highest temperature needed to be sensed?
What increments are needed? 1 degree, 5 degree, 10 degree?
