Moisture Sensitive Device Bake Time at 12% staging and temperature recovery allowance: a worked example

Push staging and temperature recovery allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. a materials or SMT engineer needs to schedule MSD recovery before a build

The inputs for this scenario

  • Required MSD bake duration: 24 hr-equivalent (unchanged)
  • Bake oven processing basis: 1 basis / hr (unchanged)
  • Staging and temperature recovery allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Required bake table time = required MSD bake duration รท bake oven processing basis) to the inputs above produces each figure below.
  • At this operating point the engine returns 26.88 hr for planned msd bake time, the number this scenario is built around.
  • At this operating point the engine returns 24 hr for required bake table time.
  • At this operating point the engine returns 12 % for staging and recovery allowance.
  • At this operating point the engine returns 1 basis / hr for bake oven processing basis.

How this compares with the baseline

  • Against the tool's baseline example, where staging and temperature recovery allowance sits at 10% and the headline result is 26.4 hr, this scenario comes in 1.82% above the baseline at 26.88 hr.
  • It converts a required J-STD-033 bake duration into a planned oven time by applying your oven's processing basis and a staging/temperature-recovery allowance. 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

  • Planned MSD bake time: 26.88 hr (headline result)
  • Required bake table time: 24 hr
  • Staging and recovery allowance: 12 %
  • Bake oven processing basis: 1 basis / hr
