Douglas Electrical Components Unveils New Technology for Hermetically Sealing Circuit Boards

New sealing method for high-volume applications allows for increased conductor density with decreased size

(RANDOLPH, N.J.: June 18, 2009) Douglas Electrical Components, Inc. (DECo) (, launches a new solution for hermetically sealing a variety of circuit board styles, including flex, rigid and hybrid circuits. Ideal for high-volume applications with certain space constraints or weight requirements, hermetically sealed circuit boards allow for increased conductor density, while providing a smaller, lighter and less expensive solution.

"The ability to hermetically seal circuit boards is extremely useful for projects that call for complex computations" says Ed Douglas, president of DECo. "These solutions are particularly significant in applications that require incredibly compact and
low-weight sealing methods, such as in missiles or bomb fuses."

Traditionally, seals are made to discrete wires and then connected or directly wired to a circuit board, using valuable space and numerous individual wire seals. By sealing directly to the circuit as opposed to each wire, the DECo solution can either
drastically increase the number of conductors used in the same size housing or reduce the size of the housing for the same conductor count. This method also takes advantage of the low-cost circuit board manufacturing process, in turn making the solution
more cost-effective than an equivalent wire feedthrough.

Additionally, by sealing directly to the circuit board, electrical connection points can be eliminated, which minimizes voltage drops and any associated labor needed to make and test the wire-to-circuit connection point.

DECo seals a variety of circuit combinations, including rigid, flex and hybrid, as well as flat flex cable (FFC). FFC offers the same size and cost advantages of the rigid and flex circuit seals, but they are available off the shelf from a variety of
electrical distributors, which makes them ideal for small quantity production runs or R&D efforts. Regardless of the combination of circuits or cables used, DECo can provide a custom engineered solution based on project needs, which can range from the number of conductors required to space constraints.

In addition to application in military and defense engineering, laser equipment and space simulation, the DECo circuit sealing method is also designed for use in semiconductor manufacturing and systems using magnetic bearings.
