Without an effective process control discipline, assembly professionals often resort to blaming the machine and changing settings when defective or marginal results occur in the wave soldering process. Instead of this approach, using good investigative tools helps significantly. Many factors other than machine setup contribute to wave soldering anomalies. Inputs to the machine such as PCBs, components and flux should be controlled to reduce random impacts on the outcome of the process. The machine should also be correctly set up and operating as desired. Because machine performance may be superficially determined in many ways, using a scientific approach for the wave soldering process, with software-based tools for equipment analysis, is productive, accurate and beneficial in today's environment.
