ICT Test Time at 21% debug and retest allowance: a worked example
Push debug and retest allowance up to 21% and the picture changes. This example computes every intermediate figure at that operating point. a test engineer is scheduling ICT tester time for a PCB assembly lot
The inputs for this scenario
- Boards requiring ICT: 850 boards (unchanged)
- ICT tested-board rate: 5.5 boards / min (unchanged)
- Debug and retest allowance: 21 % (raised for this scenario; the documented default is 18)
Working through the calculation
- Applying the documented formula (Base ICT cycle time = boards requiring ICT รท ICT tested-board rate) to the inputs above produces each figure below.
- At this operating point the engine returns 187 min for estimated ict test time, the number this scenario is built around.
- At this operating point the engine returns 155 min for base ict cycle time.
- At this operating point the engine returns 21 % for debug and retest allowance.
- At this operating point the engine returns 5.5 boards / min for ict tested-board rate.
How this compares with the baseline
- Against the tool's baseline example, where debug and retest allowance sits at 18% and the headline result is 182 min, this scenario comes in 2.54% above the baseline at 187 min.
- It estimates total ICT test time for a batch by dividing boards by the tested-board rate and inflating for a debug and retest allowance. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
