First-Pass Repair Yield at 68% target first-pass repair yield: a worked example

Suppose target first-pass repair yield falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Measure the percentage of repaired electronics that pass final functional test the first time without additional troubleshooting, rework, or repeat bench time.

The inputs for this scenario

  • Repairs passing final test first time: 8 units (held at the documented default)
  • Total repaired units tested: 250 units (held at the documented default)
  • Target first-pass repair yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: First-pass repair yield = repairs passing final test first time ÷ total repaired units tested × 100.
  • First-pass repair yield works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Yield gap to target works out to 64.8 points at these inputs.
  • Repairs passing final test first time works out to 8 count at these inputs.
  • Total repaired units tested works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target first-pass repair yield sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes the percentage of repaired units that pass final test on the first attempt and the gap between that yield and your target. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • First-pass repair yield: 3.2 % (headline result)
  • Yield gap to target: 64.8 points
  • Repairs passing final test first time: 8 count
  • Total repaired units tested: 250 count

Run it with your numbers
