Semiconductor Advanced Packaging & Test worked example

Package Inspection Load at 12% setup, handling, and reject-review allowance: a worked example

This scenario runs the package inspection load calculation on the strong side: 12% setup, handling, and reject-review allowance, with every other input held at its documented default. Use it when package inspection load in semiconductor advanced packaging and test needs a defensible run time before a quote goes out.

The inputs for this scenario

  • Packages to inspect this lot: 120 units (unchanged)
  • Inspection throughput (packages checked): 12 units / min (unchanged)
  • Setup, handling, and reject-review allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base package inspection load time = package inspection load workload รท package inspection load completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required package inspection load time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base package inspection load time.
  • At this operating point the engine returns 12 % for package inspection load allowance applied.
  • At this operating point the engine returns 12 pieces / min for package inspection load completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and reject-review allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • Use it to schedule the inspection station, size headcount, or check that inspection does not bottleneck end-of-line shipping. 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

  • Required package inspection load time: 11.2 hr (headline result)
  • Base package inspection load time: 10 hr
  • Package inspection load allowance applied: 12 %
  • Package inspection load completion rate: 12 pieces / min

Run it with your numbers

  • Every input above is editable in the live Package Inspection Load calculator, which recalculates instantly and can be shared with the inputs intact.
