Pressure Sensor Yield at 69% target first-pass yield: a worked example

This worked example runs the pressure sensor yield numbers for a tougher week than the baseline: 69% target first-pass yield instead of the typical 96%. Calculate first-pass yield for pressure sensor production by comparing units passing all accuracy, linearity, and hysteresis specs on first test against total units tested.

The inputs for this scenario

  • Sensors passing first test: 235 sensors (held at the documented default)
  • Total sensors tested: 250 sensors (held at the documented default)
  • Target first-pass yield: 69 % (the input this scenario stresses; the baseline uses 96)

Working through the calculation

  • The calculation starts from the formula this tool documents: First-pass yield = sensors passing first test / total sensors tested x 100.
  • First-pass yield works out to 94 % at these inputs, and this is the headline figure for the scenario.
  • Gap to yield target works out to -25 points at these inputs.
  • Sensors passing first test works out to 235 count at these inputs.
  • Total sensors tested works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target first-pass yield sits at 96% and the headline result is 94 %, this scenario lands almost exactly on the baseline at 94 %.
  • Use it after a test run to grade lot quality, track process trends, or trigger a containment review when yield falls short of target. 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

  • First-pass yield: 94 % (headline result)
  • Gap to yield target: -25 points
  • Sensors passing first test: 235 count
  • Total sensors tested: 250 count
