Control Board Burn-In Capacity Calculator at 66% burn-in chamber uptime: a worked example

Suppose burn-in chamber uptime falls to 66%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate appliance control board burn-in capacity from boards per burn-in batch, available batches, chamber uptime, and burn-in pass yield.

The inputs for this scenario

  • Boards loaded per burn-in batch: 96 boards/batch (held at the documented default)
  • Available burn-in batches: 18 batches/week (held at the documented default)
  • Burn-in chamber uptime: 66 % (the input this scenario stresses; the baseline uses 92)
  • Burn-in pass yield: 98 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross burn-in board capacity = boards loaded per burn-in batch × available burn-in batches.
  • Usable burn-in board capacity works out to 1,118 boards/week at these inputs, and this is the headline figure for the scenario.
  • Gross burn-in board capacity works out to 1,728 boards/week at these inputs.
  • Boards lost to chamber downtime works out to 588 boards/week at these inputs.
  • Boards failed or held after burn-in works out to 22.81 boards/week at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where burn-in chamber uptime sits at 92% and the headline result is 1,558 boards/week, this scenario comes in 28.26% below the baseline at 1,118 boards/week.
  • It computes weekly usable burn-in throughput by applying chamber uptime and burn-in pass yield to gross batch capacity. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
