Plating, Anodizing & Surface Treatment worked example

Plating Defect Rate at 99% target maximum defect rate: a worked example

This scenario runs the plating defect rate calculation on the strong side: 99% target maximum defect rate, with every other input held at its documented default. Use it when plating defect rate in plating, anodizing and surface treatment needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Defective plated parts found: 8 count (unchanged)
  • Total plated parts inspected: 250 count (unchanged)
  • Target maximum defect rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where target maximum defect rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it for incoming lot inspection, daily line quality checks, or trending a bath or rectifier issue over a run. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Plating defect rate: 3.2 % (headline result)
  • Plating defect rate gap to target: 95.8 points
  • Plating defect rate count: 8 count
  • Total plating defect rate population: 250 count
