Final Test TDR

27 August 2019 Link

Some points to consider when reviewing a TDR:


  1. Do we have a Kelvin socket - would also need it for correlation
  2. Do we have Kelvin sense over temperature?

Measurement Techniques

  1. Always ask about differential measurements for measurements as such. E.g dropout - how will it be measured differential or repeated measurements:
    Repeated measurements with the same meter at a higher voltage and then taking the difference will make the accuracy very bad since a small difference sits on a large offset voltage. Best is to measure it differentially.
  2. Make sure high power measurements are towards the end

Time saving

  1. Make a list of characterization tests that can be removed in production.
