Use of this information in real time is used for quality assurance, quality improvement and process control. Existing technology can be used to monitor, track, document and react to production during the reflow process. One area of the manufacturing process that is often overlooked is the reflow process. This does not mean the collection of all data that becomes a mass of space but rather the product and process data that can be easily analyzed, and often live for fast reaction. Useful data is imperative to clear insight, correct decisions and optimization. ![]() ![]() IntroductionÄata is the foundation of a smart factory. Key words: Automatic Profiling, Solder Reflow, Smart Factory, Process Control. Ask any CQE or Quality Engineer, they need data to support any process changes or customer complaint. An automatic profiling system (reflow process inspection) will automatically collect the thermal data at the board level for precise process control and allow traceability for every board that has been through reflow with the actual Thermal Profile, SPC, and Cpk stored for every board. This paper will talk about the reflow oven and how automatic profiling has also become a necessary tool for data analytics and troubleshooting as well as taking the guess work out of oven profiling. We have even put a great deal of technology into the back end of the process with (AOI and X-Ray) to look at every solder joint and void the board may have. We are concerned about the printing process for precise volumetric printing to the point where Solder Paste Inspection (SPI) equipment has almost become a standard on the surface mount line. There has also been a great deal of focus on the front end and the backend data for the SMT process. ![]() Data analytics has become paramount and anyone that is collecting the correct data will have proper process control to support SPC, Cpk, and Ppk data to suffice customer requirements. With the advent of i4.0 and Smart Factory, there has been a great deal of technology put into SMT lines that are manufacturing the very technologies we use today.
