Connector Polish Yield at 68% target polish yield: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target polish yield to 68%, then walk the calculation through step by step. Calculate connector polishing first-pass yield from accepted polished endfaces versus connectors polished and compare with the target.

The inputs for this scenario

  • First-pass accepted polished connectors: 232 connectors (held at the documented default)
  • Connectors polished: 250 connectors (held at the documented default)
  • Target polish yield: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Connector polish yield = first-pass accepted polished connectors ÷ connectors polished.
  • Connector polish first-pass yield works out to 92.8 % at these inputs, and this is the headline figure for the scenario.
  • Gap to polish-yield target works out to -24.8 points at these inputs.
  • First-pass accepted connectors works out to 232 connectors at these inputs.
  • Connectors polished works out to 250 connectors at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target polish yield sits at 95% and the headline result is 92.8 %, this scenario lands almost exactly on the baseline at 92.8 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target polish yield, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. First-pass yield ignores connectors recovered by rework — a cell can hit final yield while masking a poor first-pass rate that is quietly burning labor.
