UAV & Drone Manufacturing worked example

Waterproofing Yield at 99% target waterproofing pass rate: a worked example

This scenario runs the waterproofing yield calculation on the strong side: 99% target waterproofing pass rate, with every other input held at its documented default. Use it when waterproofing yield in uav and drone manufacturing needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Drones passing the ingress test: 8 count (unchanged)
  • Drones in the waterproofing test batch: 250 count (unchanged)
  • Target waterproofing pass rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where target waterproofing pass rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it after an ingress-protection test run to gauge how a sealing process is performing against a target IP pass rate. 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

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