Display Assembly Yield at 99% target display yield rate: a worked example

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

The inputs for this scenario

  • Display assemblies rejected: 8 count (unchanged)
  • Display assemblies built: 250 count (unchanged)
  • Target display yield rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where target display 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 display yield rate is genuinely sustained, not just peaked for a shift. The result depends on which count you enter as the affected quantity — enter rejects and you get a reject rate, enter good units and you get true yield; the gap-to-target only makes sense once you're consistent about that.

Results at a glance

  • Display assembly yield rate: 3.2 % (headline result)
  • Display assembly yield gap to target: 95.8 points
  • Display assembly yield count: 8 count
  • Total display assembly yield population: 250 count
