Conformal Coating Cost at 92% board area actually coated: a worked example in defense electronics & ruggedized systems

What does the result look like when board area actually coated reaches 92%? The full calculation is worked below with real intermediate numbers. Use it when conformal coating cost in defense electronics and ruggedized systems is being put through a defense electronics and ruggedized systems weighted-cost review.

The inputs for this scenario

  • Circuit card assemblies coated: 100 assemblies (unchanged)
  • Coating cost per assembly: 45 $ / assembly (unchanged)
  • Board area actually coated: 92 % (raised for this scenario; the documented default is 80)
  • Fixed masking and qualification cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Covered coating process cost = coated assemblies × coating cost per assembly × coating coverage included) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total conformal coating cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for coating cost per assembly.
  • At this operating point the engine returns 4,140 $ for covered coating process cost.
  • At this operating point the engine returns 250 $ for fixed masking and qualification cost.

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 14.03% above the baseline at 4,390 $.
  • A figure at this level is achievable when board area actually coated is genuinely sustained, not just peaked for a shift. It models coverage as a simple multiplier on per-board cost; selective-coat versus full-dip processes with very different masking burdens may need separate estimates.

Results at a glance

  • Total conformal coating cost: 4,390 $ (headline result)
