Lens mount with conductive glue pocket for grounding to a circuit board

摘要

A lens mount is attached to a circuit board and covers electrical components on the circuit board. An electrically insulating device is positioned between the lens mount and the circuit board. The circuit board includes a grounding pad adjacent the electrically insulating device. The lens mount includes an aperture aligned with the grounding pad and the electrically insulating device. A conductive glue is dispensed into the aperture to electrically ground the lens mount to the grounding pad. The electrically insulating device seals the conductive glue from the electrical components. A method of grounding a lens mount to a circuit board is provided.
