This information is provided as a reference guideline only. Your temperature profile will depend upon many factors including customer requirements, component characteristics and restrictions, oven characteristics, board layout, etc. Ultimately, quality requirements should define the profile in use, not adherence to these guidelines. These reference guidelines follow the recommendations of the standards IPC7530 for Temperature Profiling for Mass Soldering Processes, IPC9502 PWB Assembly Soldering Process Guideline for Electronic Components, IPCEIA JSTD001 Requirements for Soldered Electrical and Electronic Assemblies and IPCJEDEC JSTD020C Requirements for Small to Very Large Bodied Components. Ideally, temperature profile measurements are to be collected on a populated assembly with the reflow profile recorded for each product being processed. IPC7050 provides guidelines for the construction of reflow profiling test vehicles and various techniques for reflow temperature profiling. It is common for the same profile settings to be used for multiple assemblies. It is recommended that profile data should be collected, analyzed and recorded for each assembly part number at the beginning of individual production runs for process verification and record keeping.
