Sensor Burn-in Capacity at 63% burn-in oven uptime: a worked example

This worked example runs the sensor burn-in capacity numbers for a tougher week than the baseline: 63% burn-in oven uptime instead of the typical 88%. Calculate the net good sensors per shift from your burn-in oven or environmental chamber considering rack capacity, available cycles, uptime, and pass rate after burn-in screening.

The inputs for this scenario

  • Sensors loaded per burn-in cycle: 48 sensors / cycle (held at the documented default)
  • Burn-in cycles available per shift: 3 cycles (held at the documented default)
  • Burn-in oven uptime: 63 % (the input this scenario stresses; the baseline uses 88)
  • Post-burn-in pass rate: 98 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross burn-in capacity = sensors per cycle x available cycles per shift.
  • Net good sensors per shift works out to 88.91 units at these inputs, and this is the headline figure for the scenario.
  • Gross burn-in throughput works out to 144 units at these inputs.
  • Oven downtime loss works out to 53.28 units at these inputs.
  • Burn-in screening failures works out to 1.81 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where burn-in oven uptime sits at 88% and the headline result is 124 units, this scenario comes in 28.41% below the baseline at 88.91 units.
  • Use it when sizing burn-in oven count, committing weekly ship quantities, or finding why a sensor line misses its shippable target despite running full racks. 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

  • Net good sensors per shift: 88.91 units (headline result)
  • Gross burn-in throughput: 144 units
  • Oven downtime loss: 53.28 units
  • Burn-in screening failures: 1.81 units
