Ultrasonic Weld Yield at 68% target ultrasonic weld yield rate: a worked example

This worked example runs the ultrasonic weld yield numbers for a tougher week than the baseline: 68% target ultrasonic weld yield rate instead of the typical 95%. Estimate ultrasonic weld yield for ppe and infection control products using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Masks with sound ultrasonic welds: 8 count (held at the documented default)
  • Total masks welded and inspected: 250 count (held at the documented default)
  • Target ultrasonic weld yield rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where target ultrasonic weld yield rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it when tuning weld parameters, auditing a horn or anvil, or monitoring an assembly station for bond drift. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Ultrasonic weld yield rate: 3.2 % (headline result)
  • Ultrasonic weld yield gap to target: 64.8 points
  • Ultrasonic weld yield count: 8 count
  • Total ultrasonic weld yield population: 250 count
