Conformal Coating Yield at 68% target first-pass coating yield: a worked example

Suppose target first-pass coating 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. Estimate conformal coating yield for space payload and avionics manufacturing using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Boards passing coating inspection: 8 count (held at the documented default)
  • Total boards coated in the lot: 250 count (held at the documented default)
  • Target first-pass coating yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Conformal coating yield rate = conformal coating yield count ÷ total conformal coating yield population × 100.
  • Conformal coating yield rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Conformal coating yield gap to target works out to 64.8 points at these inputs.
  • Conformal coating yield count works out to 8 count at these inputs.
  • Total conformal coating yield population works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target first-pass coating yield sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It divides the passing (or affected) board count by the total lot population, multiplies by 100 for a percentage, and reports the point gap between that rate and the target yield. 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.
