PCBA Conformal Coating · Protection Service
Adds a protective layer to your PCBA
A bare PCBA is only at home in clean, dry environments.
But your equipment goes up mountains, out to sea, into factories, and outdoors.
If the board fails, the equipment fails.
Moisture protection
Seals out water vapor, prevents short circuits
Dust protection
Blocks contaminants, stops conductive dust buildup
Salt spray protection
Resists corrosion, keeps solder joints clean and terminals rust‑free
Chemical gas protection
Withstands acids and alkalis, ideal for chemical plants and laboratories
Vibration protection

UV protection

You specify the protection level. We spray to standard.
Thickness, coverage area, color — all customizable.
5 pieces minimum. Prototype · Small batch · Mass production — all accepted. Max 100 pieces per order.
