Thermal Interface Material Usage with tim dispense rate per hour of 30 units / hr: a worked example

This scenario runs the thermal interface material usage calculation on the strong side: tim dispense rate per hour of 30 units / hr, with every other input held at its documented default. Use it when budgeting thermal grease, gap filler, phase-change pad, or dispense material for power electronics builds.

The inputs for this scenario

  • TIM dispense rate per hour: 30 units / hr (raised for this scenario; the documented default is 12)
  • Dispensing line runtime: 8 hr (unchanged)
  • TIM cost per dispensed unit: 3.5 $ / unit (unchanged)

Working through the calculation

  • Applying the documented formula (Thermal interface material consumed = TIM dispense or use rate × production or dispense runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 840 $ for thermal interface material run cost, the number this scenario is built around.
  • At this operating point the engine returns 240 units for thermal interface material consumed.
  • At this operating point the engine returns 8 hr for production or dispense runtime.
  • At this operating point the engine returns 3.5 $ / unit for tim material cost.

How this compares with the baseline

  • Against the tool's baseline example, where tim dispense rate per hour sits at 12 units / hr and the headline result is 336 $, this scenario comes in 150% above the baseline at 840 $.
  • Use it when quoting a build, budgeting consumable spend for a shift or week, or validating whether dispense volume matches material draw-down. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
