ABSTRACT:
A high pressure steam condensation soldering facility (10) is described. The facility (10) incorporates a chamber (12) having a centrally located heat processing zone (45) into which high pressure steam is injected to reflow solder on articles (43) therein. A baffle (41) having a conical top portion (51) with a plurality of apertures (52) therein permits controlled amounts of the steam to pass therethrough while redirecting a portion of the steam along the wall (16) of the chamber (12) to interpose a shield of steam between the wall and uniformly heated processing zone (45).
