at room temperature
Apply test voltage at 70oC for 1000 hours. Allow to cool to room
temperature and measure Cap, DCL and ESR
Maintain at 70oC for 1000 hours with no voltage applied. Allow to
cool to room temperature and measure Cap, DCL and ESR.
Maintain at 40°C / 95% RH for 1000 hours. Allow to cool to room
temperature and measure Cap, DCL and ESR.
Apply an increasing force in shear mode until leg pulls away
