Specialty Films, Membranes & Barrier Materials worked example

Lamination Yield at 99% target lamination yield rate: a worked example in specialty films, membranes & barrier materials

What does the result look like when target lamination yield rate reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when lamination yield in specialty films, membranes and barrier materials needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Rejected laminate rolls (delamination, bubbles, tunneling): 8 count (unchanged)
  • Total laminate rolls inspected: 250 count (unchanged)
  • Target lamination yield rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where target lamination 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 lamination yield rate is genuinely sustained, not just peaked for a shift. The tool divides the first field by the total, so if you enter defects rather than good rolls the headline rate reflects the defect share — read the result in the context of what you entered.
