pcb potting

PCB potting provides a protective barrier against moisture, vibration, and environmental stress. EI Microcircuits uses precise potting techniques to enhance durability and reliability in harsh or mission-critical conditions.

our potting

process

01.

Preparation & Material Selection

Boards are cleaned, masked, and matched with the ideal potting compound—chosen based on thermal, mechanical, and environmental needs.

02.

Controlled Application

Potting material is dispensed with precision to ensure complete coverage, void-free encapsulation, and consistent protection across assemblies.

03.

Curing & Final Inspection

Assemblies are cured under controlled conditions and undergo thorough inspection to verify full protection and performance readiness.

"A delightful company to work with. Could not have done it without your expertise."

"EI excels in responsiveness, support and flexibility. I very much appreciate EI’s ability to adapt on the fly."

"I appreciate the work EI does most of all because it makes my job easier."

"Overall, EI does a great job in dealing with everything we throw at them. They are responsive and understanding of us, even though it may not always be the most reasonable of requests. As a buyer, I feel lucky to have a supplier that works with us like they do."

"Working on a project that had a board that was simply not manufacturable the way it was set up, EI went above and beyond to help with engineering and still met a very short deadline."
