Abstract: In making diode bridges 16, it is desirable to solder a plurality of such bridges simultaneously. To accomplish this a plurality of diodes 10 are held by a portion of one lead each in a cantilevered fashion in each of four in-line racks 38, 40, 50 and 52. The four racks 38, 40 50 and 52, with diodes 10 extending therefrom, are held at a fixed angle and fixed spacing with respect to each other to interleave the diode leads 14 and form channels. Solder wire 62 is placed in each of the channels. The diodes 10 and the solder wires 62 are then placed into either a heated gas or heated saturated vapor to melt the solder at the crosspoints 60 of the leads 14. Troughs 64 are provided adjacent the crosspoints 60 to catch any solder runoff which occurs during the melting.

Abstract: Wafer-like articles are inserted through an input port into one of a plurality of slots in a rotatable disc having a slotted periphery. The disc is disposed in a vertical plane between a pair of closely-spaced parallel plates which laterally retain the articles in the slots. The slots advantageously are inclined toward the direction of rotation so that the wafers tend to remain therein as rotation and treating proceeds. The rotating disc urges each article between the plates to an aperture in one of the plates through which one side of the article is exposed to a treating medium, such as a scrubbing brush and detergent solution. Further rotation of the disc brings each article to an aperture in the opposing plate through which another side of the article is exposed to another treating medium of like or different kind.
