Conformal Coat Removal Time at 7.2% masking, cleaning, and inspection allowance: a worked example

Suppose masking, cleaning, and inspection allowance falls to 7.2%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate technician hours to remove conformal coating before board-level repair, component replacement, solder touch-up, inspection, or retest.

The inputs for this scenario

  • Coated boards requiring removal: 120 boards (held at the documented default)
  • Coating removal pace: 12 boards / hr (held at the documented default)
  • Masking, cleaning, and inspection allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base conformal coat removal hours = coated boards requiring removal รท coating removal pace.
  • Required conformal coat removal time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base conformal coat removal hours works out to 10 hr at these inputs.
  • Masking, cleaning, and inspection allowance works out to 7.2 % at these inputs.
  • Coating removal pace works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where masking, cleaning, and inspection allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • It computes the required conformal coat removal hours by dividing board count by removal pace and inflating the result with a masking, cleaning, and inspection allowance. 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.

Results at a glance

  • Required conformal coat removal time: 10.72 hr (headline result)
  • Base conformal coat removal hours: 10 hr
  • Masking, cleaning, and inspection allowance: 7.2 %
  • Coating removal pace: 12 pieces / min
