Dip, Dry, Ship: Bottlenecks with NanoProof® Coatings
Why Throughput Is the Real Cost of Conformal Coating
Masking, oven cures, and long vacuum cycles that tie up people, ovens, and capital equipment overshadow the coating resin cost. In many plants, masking labor and rework hours outweigh raw-material spend—especially on complex boards with fine-pitch connectors.
Traditional options make the problem worse:

Enter NanoProof®: 10 Minutes from Dip to Functional Test
NanoProof® treatments are single-step dip, spray, or jet coatings that require no thermal cure. Boards come off the line tack free in minutes, ready for downstream test or final assembly.
- Room-temperature process – no ovens, no ramp-up, no cooldown.
- Ultrathin 10 nm–9 µm films – zero impact on connector fit or signal integrity.
- IPX7–IPX8 water-immersion proven – durability that matches or beats conformal acrylics at a fraction of the thickness.

Result: A single coating line running an eight-hour shift can finish approximately 40 times more boards per day with NanoProof® than with Parylene, or approximately 5 times more than with oven-cured acrylics—without adding staff or capital equipment (assumes identical panel load sizes; conservative labor estimates).
Labor: No masking tape means no peel-and-inspect—reducing touch time and repetitive-motion risk.
Rework: Ultrathin films lower the chance of bubbles, bridging, and thickness failures.
Compliance: There is no intentional PFAS; RoHS-compliant chemistry simplifies future audits.
Beyond Speed: Hidden Savings That Hit the P&L
Energy: Eliminating 75 °C bake cycles cuts oven kWh consumption to zero.Labor: No masking tape means no peel-and-inspect—reducing touch time and repetitive-motion risk.
Rework: Ultrathin films lower the chance of bubbles, bridging, and thickness failures.
Compliance: There is no intentional PFAS; RoHS-compliant chemistry simplifies future audits.
Implementation Checklist (Dip, Dry, Ship in Three Steps)
- Lab-line proof: Treat 5–10 sample boards via dip or spray; run functional and IPX testing.
- Cost-in-use audit: Compare masking labor, cure energy, and takt time deltas against legacy process.
- Scale and train: Install a simple dip tank or automated spray cell; update work instructions—no oven PLC rewrites are required.
