PCB Potting & Protection
How to pot and protect printed circuit boards against moisture, vibration and heat for long-term field reliability.
Protect Printed Circuit Boards
PCBs in harsh environments need protection from humidity, condensation, vibration and heat. Potting encapsulates the board in a protective block, while conformal coating provides a lighter thin-film alternative.
JOME supplies potting compounds and PCB-safe adhesives — including thermally conductive and flame-retardant grades — for reliable board protection.
Recommended Products for PCBs
Potting Compounds
Encapsulate boards for full protection.
Conformal Coatings
Thin-film moisture and dust protection.
Thermal Adhesives
Manage heat on dense boards.
PCB Protection Considerations
- Humidity and condensation exposure
- Vibration and shock levels
- Board temperature and hot spots
- Conformal coating vs full potting
- Flame-retardancy requirements
- Reworkability needs
- Connector and component masking
- Production volume and cure speed
Frequently Asked Questions
Place the board in a housing, mix and pour the potting compound to cover the components, remove air bubbles, then cure. JOME can recommend a resin and process for your board.
Potting offers maximum protection by full encapsulation; conformal coating is lighter and reworkable. Choose by the protection level, weight and rework requirements.
