Semiconductor Advanced Packaging & Test worked example

Semiconductor Line OEE at 68% performance efficiency vs rated speed: a worked example

This worked example runs the semiconductor line oee numbers for a tougher week than the baseline: 68% performance efficiency vs rated speed instead of the typical 95%. Calculate OEE for Semiconductor Advanced Packaging & Test from availability, performance, and quality to see how much of planned production time becomes good output.

The inputs for this scenario

  • Actual equipment run time: 410 min (held at the documented default)
  • Planned production time: 480 min (held at the documented default)
  • Performance efficiency vs rated speed: 68 % (the input this scenario stresses; the baseline uses 95)
  • First-pass test yield: 98 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Availability = operating time รท planned production time.
  • OEE works out to 56.92 % at these inputs, and this is the headline figure for the scenario.
  • Availability works out to 85.42 % at these inputs.
  • Performance works out to 68 % at these inputs.
  • Quality works out to 98 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where performance efficiency vs rated speed sits at 95% and the headline result is 79.52 %, this scenario comes in 28.42% below the baseline at 56.92 %.
  • Use it in daily or weekly line reviews, when benchmarking cells, or when building the loss case for a capital or maintenance investment. 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

  • OEE: 56.92 % (headline result)
  • Availability: 85.42 %
  • Performance: 68 %
  • Quality: 98 %

Run it with your numbers

  • To rerun this with your own numbers, open the live Semiconductor Line OEE calculator, set performance efficiency vs rated speed to your actual value, and adjust the remaining inputs to match your operation.
