Abstract
An apparatus for mounting a printed circuit board within a potted member and enhancing the environmental isolation of the circuit board includes a first rigid tubular member and a second elastomeric tubular member. The elastomeric member is positioned about the rigid member and bonded thereto. The tubular members are inserted through openings in the circuit board to support the circuit board at a preselected height and provide bolt hole openings through the first rigid member for mounting the assembly at a desired location. A potting compound is applied in enveloping relation to the circuit board and elastomeric member while maintaining a clear passage through the bolt hole openings. The potting compound chemically bonds to the elastomeric member virtually eliminating water intrusion at the interface between the elastomeric member and the potting compound.
