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:
The disclosure provides an internal heat-dissipation terminal, wherein the terminal comprises at least one cavity in which heat-storage material is arranged. The cavity is located in an area without a device in the terminal. The technical solution of the disclosure can be applied to substantially enhance the heat storage capability of the terminal.
