Electronics Repair, Refurbishment & Depot Operations worked example

Burn-In Test Capacity at 99% expected burn-in rack uptime: a worked example in electronics repair, refurbishment & depot operations

This scenario runs the burn-in test capacity calculation on the strong side: 99% expected burn-in rack uptime, with every other input held at its documented default. Use it when burn-in test capacity in electronics repair, refurbishment and depot operations is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Units loaded per burn-in cycle: 4 units / cycle (unchanged)
  • Available burn-in cycles: 480 cycles (unchanged)
  • Expected burn-in rack uptime: 99 % (raised for this scenario; the documented default is 90)
  • Expected burn-in pass yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross burn-in capacity = units loaded per burn-in cycle × available burn-in cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units / shift for good burn-in test capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units / shift for gross burn-in capacity.
  • At this operating point the engine returns 19.2 units / shift for burn-in rack downtime loss.
  • At this operating point the engine returns 57.02 units / shift for burn-in yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where expected burn-in rack uptime sits at 90% and the headline result is 1,676 units / shift, this scenario comes in 10% above the baseline at 1,844 units / shift.
  • Use it to size burn-in racks against repair output, plan shift capacity, or check whether burn-in is gating shipments. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Good burn-in test capacity: 1,844 units / shift (headline result)
  • Gross burn-in capacity: 1,920 units / shift
  • Burn-in rack downtime loss: 19.2 units / shift
  • Burn-in yield loss: 57.02 units / shift
