PCB Test Yield at 99% target pcb test yield: a worked example
What does the result look like when target pcb test yield reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when ICT, functional test, programming, boundary scan, power-on checks, RF checks, or final system test results need to show how many boards pass without rework.
The inputs for this scenario
- PCBs passing first-pass test: 925 boards (unchanged)
- PCBs tested: 1,000 boards (unchanged)
- Target PCB test yield: 99 % (raised for this scenario; the documented default is 97)
Working through the calculation
- Applying the documented formula (PCB test yield rate = PCBs passing first-pass test ÷ PCBs tested × 100) to the inputs above produces each figure below.
- At this operating point the engine returns 92.5 % for pcb test yield rate, the number this scenario is built around.
- At this operating point the engine returns 6.5 points for pcb test yield gap to target.
- At this operating point the engine returns 925 count for pcbs passing first-pass test.
- At this operating point the engine returns 1,000 count for pcbs tested.
How this compares with the baseline
- Against the tool's baseline example, where target pcb test yield sits at 97% and the headline result is 92.5 %, this scenario lands almost exactly on the baseline at 92.5 %.
- A figure at this level is achievable when target pcb test yield is genuinely sustained, not just peaked for a shift. First-pass yield doesn't credit boards that pass on retest after rework, so it can understate final shippable yield on lines with high rework recovery.
