ENVIRONMENTALLY PROTECTED CIRCUIT BOARD

摘要

Environmentally Protected Circuit Board A printed circuit board is mounted within a potted member via a plurality of standoffs. Each standoff 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 standoffs 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. The potted member thereby formed is chemically bonded to the elastomeric member and virtually eliminates water intrusion at the interface. In this manner environmental isolation of the circuit board is enhanced.
