Conformal Coating Cost at 58% board area actually coated: a worked example in defense electronics & ruggedized systems

Suppose board area actually coated falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate coating cost for defense circuit card assemblies, embedded boards, rugged displays, radios, sensors, and sealed electronic modules.

The inputs for this scenario

  • Circuit card assemblies coated: 100 assemblies (held at the documented default)
  • Coating cost per assembly: 45 $ / assembly (held at the documented default)
  • Board area actually coated: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed masking and qualification cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Covered coating process cost = coated assemblies × coating cost per assembly × coating coverage included.
  • Total conformal coating cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Coating cost per assembly works out to 28.6 $ / piece at these inputs.
  • Covered coating process cost works out to 2,610 $ at these inputs.
  • Fixed masking and qualification cost works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where board area actually coated sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • It multiplies the number of coated assemblies by the per-assembly coating cost and the coverage fraction, then adds the fixed masking and qualification cost. 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.
