Final Test Capacity at 65% expected test-station uptime: a worked example in payment terminal & retail hardware

This worked example runs the final test capacity numbers for a tougher week than the baseline: 65% expected test-station uptime instead of the typical 90%. Estimate final test capacity for payment terminal and retail hardware using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Terminals tested per cycle: 4 units / cycle (held at the documented default)
  • Available final-test cycles: 480 cycles (held at the documented default)
  • Expected test-station uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Expected first-pass yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross final test capacity = final test capacity output per cycle × available final test capacity cycles.
  • Good final test capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross final test capacity works out to 1,920 units at these inputs.
  • Final test capacity downtime loss works out to 672 units at these inputs.
  • Final test capacity yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected test-station uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • Use it when sizing a final-test cell, deciding fixture parallelism, or checking whether test throughput can support the assembly line's build rate. 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

  • Good final test capacity: 1,211 units (headline result)
  • Gross final test capacity: 1,920 units
  • Final test capacity downtime loss: 672 units
  • Final test capacity yield loss: 37.44 units
