Abstract:
A circuit-board heater comprising:a circuit-board support sized and shaped to support a printed-circuit board thereon; a gas source; a supply conduit including a conduit outlet and including a conduit inlet in such fluid communication with the gas source as to receive a gas flow therefrom; a heat source in such thermal communication with the interior of the supply conduit as to heat gas flowing therein and thereby result in heated-gas flow from the conduit outlet; and a diffuser consisting essentially of an open-cell metal foam, forming an outlet face, and being so interposed between the conduit outlet and the circuit-board support that, when the circuit-board support is supporting a printed-circuit board, gas from the conduit outlet passes through the diffuser and issues from the outlet face toward the printed-circuit board.
