Advanced Packaging Yield at 99% target advanced packaging yield rate: a worked example

What does the result look like when target advanced packaging yield rate reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when advanced packaging yield in semiconductor advanced packaging and test needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Good advanced packages passing final inspection: 8 count (unchanged)
  • Total advanced packages processed in lot: 250 count (unchanged)
  • Target advanced packaging yield rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Advanced packaging yield rate = advanced packaging yield count ÷ total advanced packaging yield population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for advanced packaging yield rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for advanced packaging yield gap to target.
  • At this operating point the engine returns 8 count for advanced packaging yield count.
  • At this operating point the engine returns 250 count for total advanced packaging yield population.

How this compares with the baseline

  • Against the tool's baseline example, where target advanced packaging yield rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • A figure at this level is achievable when target advanced packaging yield rate is genuinely sustained, not just peaked for a shift. It is a simple pass/fail ratio — it does not weight defects by cost, distinguish rework-recoverable failures from hard scrap, or account for known-good-die incoming quality.

Results at a glance

  • Advanced packaging yield rate: 3.2 % (headline result)
