Douglas - Model CircuitSeal - Hermetic Circuit Assemblies - Brochure

CircuitSeal is the process of hermetically sealing and encapsulating connectors and electronic circuits within a low-outgassing, chemically inert hermetic epoxy. By encapsulating the circuit board, connector, or flex circuit, customers have increased design flexibility to design a small, lightweight electronic package. CircuitSeal can integrate a variety of circuit board and electrical connection types including flex, rigid, hybrid and flat flex cable (FFC). Circuit board encapsulation protects against corrosion and electrical shorts caused by water vapor and condensation or creates a hermetic barrier between the circuit and housing assembly or enclosure.
