Abstract
An alignment fixture for aligning components of a solder-wave machine during manufacturing processes of PCB assemblies and other electronic devices. In one embodiment, an alignment fixture has a calibration member that is adapted to be positioned at least in part over a solder-wave of the solder-wave machine. The calibration member may be positioned at a PCB elevation defined by the elevation at which PCB assemblies move over the solder-wave during processing. The calibration member may be an alignment bar or other device that has a solder indicator to indicate the height of the solder-wave relative to the PCB elevation. Additionally, the solder indicator may indicate the extent of deviations between the height of the solder-wave and the PCB elevation across at least a portion of the solder-wave. The alignment fixture, therefore, not only determines whether the solder-wave will sufficiently cover the back side of the PCB, but it may also determine the locations where the nozzles are misaligned and the extent of any such misalignments.
