Hi Jeff, Thirty-two daisy-chains of eight capacitors in series were used to increase the number of capacitors on test from 32 to 256 without having to increase the monitoring capacity, which is expensive. I would also like to point out, that SM-785 "Guidelines for Accelerated testing..." is really not a good tool for 'process validation', it has much more to do with assuring that the design of your assemblies is suited for its application——'Design For Reliability (DfR).
