Electronics Repair, Refurbishment & Depot Operations calculator

First-Pass Repair Yield Calculator

Measure the percentage of repaired electronics that pass final functional test the first time without additional troubleshooting, rework, or repeat bench time. Two counts and a target give you a rate plus how far you are from where you need to be.

What this calculator does

  • Measure the percentage of repaired electronics that pass final functional test the first time without additional troubleshooting, rework, or repeat bench time.
  • Use it when first-pass repair yield in electronics repair, refurbishment and depot operations needs a clean rate and gap-to-target you can put on a tier board.
  • Turns repairs passing final test first time, total repaired units tested, target first-pass repair yield into a rate for first-pass repair yield in electronics repair, refurbishment and depot operations.

Formula used

  • First-pass repair yield = repairs passing final test first time ÷ total repaired units tested × 100
  • Yield gap to target = first-pass repair yield - target first-pass repair yield

Inputs explained

  • Repairs passing final test first time: undefined
  • Total repaired units tested: undefined
  • Target first-pass repair yield: undefined

How to use the result

  • Use it when first-pass repair yield in electronics repair, refurbishment and depot operations is being reviewed against a KPI.
  • Trend matters more than a single snapshot; pull the result for the last several periods before you act.

Common questions

  • What problem does this first-pass repair yield calculator solve? Measure the percentage of repaired electronics that pass final functional test the first time without additional troubleshooting, rework, or repeat bench time. You get a rate you can defend before quoting, scheduling, or sign-off.
  • Which inputs change the rate the most? repairs passing final test first time, total repaired units tested, target first-pass repair yield usually move the rate most. Pull from measured electronics repair, refurbishment and depot operations runs, supplier data, and recent quotes rather than memory.
  • How should I act on the output? Use the gap to target to prioritize the next electronics repair, refurbishment and depot operations kaizen or corrective action.
  • What can throw the result off? Confirm the counts came from the same time window and the same scope; mismatched scope is the most common error.
