ABSTRACT:
A supporting tray for moving a PCB (10) in a wave solder machine includes a frame (30) and a circular plate (20). The frame includes a circular opening (33) defined thereof and a graduated scale (31) marked thereon around the circular opening. The circular plate includes a recessed portion (23). Two aligned pointers (21) are marked at two opposite outer sides of the recessed portion. In assembly, the PCB is fixedly received in the recessed portion of the circular plate. The combined PCB and circular plate is then rotatably received in the circular opening of the frame. Then the assembled PCB and the supporting tray are transported to a wave solder machine. The angle of the PCB with respect to a direction of flow of solder waves can be adjusted with an indication of the pointers and the scale. Consequently the optimal angle can be efficiently and accurately ascertained.
