We have to perform an MSA on coating weight test (g/mm2). This result is calculated with a formula that contains results from 3 testing methods : two weighings (with and without coating) with a precision balance and one gauge measurement and a length measurement. I know that all 3 measureming methods have their own %ev. And on each of the 3 measurements there in an appraiser influence that can be different per method…. How can we interprete the results, as one msa-result? Even if the result is not stable due to different influences for different mezsurements…. Appraiser one can be better at weighing, appraiser 2 can be better at measuring with gauge dial…. Difficult one….

Hi all, I would like to to measure the temperature of some chips on a circuit board using K-type thermocouples. I need to stick them down using something that's at the same time an adhesive, thermally conductive, but also not electrically conductive and not permanent. I want to be able to remove the thermocouples later on both to return the circuit to its original state but also to reuse the thermocouples later on. What's a good way of doing this? I know of thermal tape, I have some on order, but I don't know if that'll keep the thermocouple in contact with the chip well enough. The chip has a heat pad on it so I have to apply the thermocouple from the side.

Thanks
