What I like to see is the overall test step yield. Example: 200 devices tested, each with 10 steps. All devices passed, the test yield is 100%. But each step No.2 of each device failed first and passed after one repeat. Each device has then 11 steps run and tested, 10 steps passed, one failed. For all 200 devices: 2.000 steps passed, 200 steps failed. This is an “overall test step yield” of 90,9%, and a device test yield of 100%. I like to get the 90,9% somehow. Possible?
