Recommended ir reflow profile

WebbThe Reflow Profile of SMT concerns many factors, such as Flux, PCB Layers, PCB Dimension, Components Type/Location, Package Thickness/Volume, and so on, so we cannot directly determine the Reflow Profile of SMT by an IC Package. - For the definition of Reflow Profile, please refer to IPC/JEDEC J-STD-020E (Please refer to the appendix). WebbProfiling the PPT of components on the board is also recommended. Packages that were qualified prior to the release of J-STD-020B in August 2002 may have only been qualified for a maximum PPT of 225 °C. If semiconductor packages are subjected to process temperatures higher than those used for qualification, reliability issues can occur. 3.
