Encapsulation level control system for electronic circuit(s)

摘要

A device used for the encapsulation of electronic circuitry without functional interference e.g. by dust and moisture vapour, comprises an encapsulation chamber in which the level of encapsulant is adjusted by vertical concentric tube(s), having uppermost edge of each tube defining an overflow weir, setting the level of the fluid encapsulant. Encapsulant is pumped around a recirculation system, with the upper and outer tube threaded to the inner, screwed up or down for precision adjustment.
