for printed circuit boardsfor electrical cablesfor electronics

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). Douglas encapsulates customer electronics and circuits to protect against corrosion and electrical shorts caused by water vapor and condensation or creates a hermetic barrier between the circuit and housing assembly or enclosure. Non-hermetic connectors offer more design options and are lower cost than their hermetic counterparts. Douglas Electrical can hermetically seal a non-hermetic connector and directly integrate it into the circuit board or flex circuit offering a moisture tight seal as well as connector headers and receptacles. CircuitSeal hermetic packages create cost-effective solutions be enabling customers to use smaller mechanical packages to protect electronics. The mechanical interface can also be customized to simply sit on a hermetic circuit or integrate a housing such as a radial O-ring, jamnut, or bulkhead housing. This adds design flexibility to not only seal the circuit but the mechanical interface that the circuit is designed within including control boxes, housings, and custom assemblies. Our epoxy and the mechanical assemblies can be designed for both vacuum and positive pressure and a wide temperature range.
