Electronics Repair, Refurbishment & Depot Operations worked example

Test Fixture Utilization at 99% target fixture utilization: a worked example in electronics repair, refurbishment & depot operations

Push target fixture utilization up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when test fixture utilization in electronics repair, refurbishment and depot operations needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Fixture hours actually run on board test: 8 fixture hr (unchanged)
  • Fixture hours available on the depot calendar: 250 fixture hr (unchanged)
  • Target fixture utilization: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Test fixture utilization = fixture hours used ÷ fixture hours available × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for test fixture utilization, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for fixture utilization gap to target.
  • At this operating point the engine returns 8 count for fixture hours used.
  • At this operating point the engine returns 250 count for fixture hours available.

How this compares with the baseline

  • Against the tool's baseline example, where target fixture utilization sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It computes the percentage of available test-fixture hours that were actually used to run boards, plus the point gap to your utilization target. 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

  • Test fixture utilization: 3.2 % (headline result)
  • Fixture utilization gap to target: 95.8 points
  • Fixture hours used: 8 count
  • Fixture hours available: 250 count
