Firmware Programming Load Calculator with active firmware programming stations of 10 stations: a worked example

What does the result look like when active firmware programming stations reaches 10 stations? The full calculation is worked below with real intermediate numbers. a test or production engineer needs to estimate firmware loading capacity and cost for control board builds

The inputs for this scenario

  • Active firmware programming stations: 10 stations (raised for this scenario; the documented default is 4)
  • Programming runtime: 9.5 hr (unchanged)
  • Programming station-hour cost: 38 $ / station-hr (unchanged)
  • Control boards programmed: 3,100 boards (unchanged)

Working through the calculation

  • Applying the documented formula (Firmware programming station-hours = active firmware programming stations × programming runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 3,610 $ for firmware programming workload cost, the number this scenario is built around.
  • At this operating point the engine returns 95 station-hr for firmware programming station-hours.
  • At this operating point the engine returns 1.16 $ / board for programming cost per board.
  • At this operating point the engine returns 380 $ / hr for programming cost per hour.

How this compares with the baseline

  • Against the tool's baseline example, where active firmware programming stations sits at 4 stations and the headline result is 1,444 $, this scenario comes in 150% above the baseline at 3,610 $.
  • A figure at this level is achievable when active firmware programming stations is genuinely sustained, not just peaked for a shift. It assumes stations run the full runtime productively; real utilization drops with handling, first-article checks, and changeovers, raising true cost per board.

Results at a glance

  • Firmware programming workload cost: 3,610 $ (headline result)
  • Firmware programming station-hours: 95 station-hr
  • Programming cost per board: 1.16 $ / board
  • Programming cost per hour: 380 $ / hr
