Abstract: An improvement in a reflow soldering apparatus for bonding a connector element such as flexible circuitry or a pin type input/output (I/O) connector to a printed circuit board (PCB) is disclosed wherein a fixture tray included in the apparatus automatically aligns or self levels itself with the heating bars, or thermodes, of the apparatus. The fixture tray includes a body for supporting the connector/PCB assembly and cylindrical rods extending from the body. The rods are rotatably supported in corresponding grooves on the surface of the fixture tray table. As a thermode is pressed onto the connector/PCB assembly, the fixture tray rotates about its axis of rotation until the work area is aligned with the thermode. In a sandwich type soldering application including a pair of thermodes for simultaneously soldering opposite sides of a connector/PCB assembly, the fixture tray rests on an upper plate of a tray table supported by resilient means such as springs.
