Abstract: A method and circuit board arrangement for an intrinsically safe portable device includes two or more circuit boards having a frame structure that forms a contiguous boundary around a space between the circuit boards. In the space there are circuit components mounted on both circuit boards, and a connector that connect the two circuit boards. An encapsulant material fills the space bounded by the frame structure between the circuit boards to exclude airborne material from coming into contact with the encapsulated circuit components.

Abstract: A push-to-talk assembly includes a metal ring defining an interior aperture and including at least one exterior protrusion configured to couple the metal ring to a surface of the portable communication device. The push-to-talk assembly further includes a button coupled to the metal ring and including a flexible polymer material disposed within the interior aperture and co-molded to the metal ring. The button includes a first side configured to be contacted and pressed, and a second, opposite side configured to face an interior of the portable communication device. The push-to-talk assembly further includes a metal backing plate coupled to the second side of the button.
