Abstract
Abstract Vapor condensation mass soldering apparatus (46) is of modular construction and includes a primary vapor zone assembly (50), a secondary vapor zone assembly (52), an ambient air moisture-removal zone assembly (54) and a hood assembly (56) mounted in readily separable, vertically stacked relationship. An article load-unload assembly (48) is secured to the front of the other assemblies (50, 52, 54 and 56). Each of the zone assemblies (50, 52 and 54) also includes respective condenser coil modules (142, 150 and 154) of special construction which can readily be mounted on and removed from their respective assemblies as integral units.

Claim 3
Dependent Claim
70 words
Vapor condensation apparatus as recited in claim 1, in which each of the condenser coil means further includes: spaced headers mounted on the interior section of the associated mounting plate on the inner side of the mounting plate, the inlet and outlet means for the condenser coil means each being connected to one of the headers; and a plurality of conduits extending between the headers parallel to the mounting plate.
Claim 4
Dependent Claim
