How do you calculate conformal coating cost per board?

Total coating cost divided by boards coated. Here $4,010 total over 8,000 boards is about $0.50 per coated board once the $650 fixed setup is spread across the run.

What does conformal coating cost per board for appliance controllers?

Typical selective or dip coating runs $0.30-$1.00 per board in material and labor depending on coverage area and chemistry. The example lands at $0.50125 per board including fixed setup.

Why include a masking and cure validation cost?

Masking connectors and edge fingers, building fixtures, and validating the cure oven profile are real fixed costs that do not scale with board count. The example carries $650 of this, which is why per-board cost exceeds the $0.42 variable rate.

How does coating coverage percent affect the cost?

The boards-requiring-coating percent scales the variable cost. At 100% every board is coated; if only 60% needed coating the variable piece would drop proportionally while the $650 fixed cost stayed the same.

Is selective coating cheaper than dip coating?

Selective coating cuts masking labor and material waste but adds equipment and program-setup cost. Run both through this calculator with their own per-board and fixed inputs to compare on cost per coated board.

What is the variable versus total coating cost here?

Variable cost is 8,000 boards times $0.42 times 100%, or $3,360. Adding the $650 fixed setup gives the $4,010 total.

Appliance Electronics & Control Boards calculator

Conformal Coating Cost Calculator

Conformal coating cost is the all-in spend to protect appliance control boards against humidity, condensation, and dust with an acrylic, urethane, or silicone film. Process engineers on dishwasher, HVAC, and outdoor-unit board lines need this figure because coating is often the difference between a board surviving years in a damp, thermally cycled enclosure and a warranty failure. The cost splits into a per-board variable piece — material plus apply-and-cure labor — and fixed work like masking connectors, fixturing, and cure-oven validation. This calculator combines both so you can quote, budget, and compare selective coating against dip or spray methods on a real cost-per-board basis.

What this calculator does

Estimate conformal coating cost for appliance control boards from coated board count, coating cost per board, coverage share, and fixed setup cost.
a process engineer or estimator needs to price conformal coating for appliance control board production
It computes total conformal coating cost as coated boards times per-board cost times the coating-required share, added to fixed masking and cure setup cost, plus the resulting cost per coated board.

Formula used

Variable conformal coating cost = control boards coated × coating material and labor cost × boards requiring conformal coating
Total conformal coating cost = variable conformal coating cost + masking, setup, and cure validation cost

Inputs explained

Control boards coated:
Coating material and labor cost:
Boards requiring conformal coating:
Masking, setup, and cure validation cost:

How to use the result

Use it when quoting a coating operation, budgeting a line, or comparing selective versus full-board coating processes for appliance controllers.
It treats per-board material and labor as a flat rate; real selective-coat cycle time and material usage vary with board geometry and keep-out complexity.

Current U.S. benchmarks

The producer price index for copper and brass mill shapes stands at 559.593 (BLS, May 2026), up 76.8% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,484 per tonne (IMF via FRED, May 2026).
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
The U.S. has 11,261 computer and electronic products establishments employing about 815,443 workers (Census County Business Patterns, 2023).
