Thermal Profile Window at 99% profile equipment uptime: a worked example

Push profile equipment uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when temperature uniformity surveys, load thermocouple checks, or recipe profile verifications constrain release.

The inputs for this scenario

  • Profiles reviewed per cycle: 2 profiles / cycle (unchanged)
  • Available profile cycles: 8 cycles / shift (unchanged)
  • Profile equipment uptime: 99 % (raised for this scenario; the documented default is 90)
  • Accepted profile yield: 95 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross thermal profile capacity = profiles reviewed per cycle × available profile cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 15.05 profiles / shift for accepted thermal profile capacity, the number this scenario is built around.
  • At this operating point the engine returns 16 profiles / shift for gross profile capacity.
  • At this operating point the engine returns 0.16 profiles / shift for profile equipment downtime loss.
  • At this operating point the engine returns 0.79 profiles / shift for profile reject loss.

How this compares with the baseline

  • Against the tool's baseline example, where profile equipment uptime sits at 90% and the headline result is 13.68 profiles / shift, this scenario comes in 10% above the baseline at 15.05 profiles / shift.
  • It computes the accepted thermal profiling capacity per shift by derating gross profile capacity (output per cycle times available cycles) for equipment uptime and accepted yield. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Accepted thermal profile capacity: 15.05 profiles / shift (headline result)
