This video is part two of our examination of how surface mount technology (SMT) is used to assemble PCBs and transform them into PCBAs. • In this video, we continue to look at the PCBA production process where SMT is being used to assemble these important boards found in electronic devices. • We will look at the next 2 elements of the PCBA production process on an SMA (surface mount assembly) line in detail: The reflow soldering process (heating and colling phases) and cleaning process (cleaning of solder flux residue and examples of what to avoid). • In particular, we'll cover: • The thermal profiles for preheating, heating and coll down cycles (because PCBs must be heated before soldering in order for the flux in the solder paste to be activated) • The importance of cleaning after soldering (electro-migration can occur when displaced particles cause accidental bridging between two parts of a circuit) • Benefits of 'no clean' solder paste • After watching this video, importers will have a much clearer understanding of how the PCBAs used in their electronic devices are actually being made, and the intricate production process that your suppliers are undertaking on your behalf. • ________________________________________________________________________ • Watch the rest of these PCB-related videos in this playlist: • PCB PCBA Production (Important Fabr... • If you have any questions regarding producing YOUR electronic products that use PCBs, or need help, feel free to contact us over at Sofeast: https://www.sofeast.com/contact-us/ • You may also like to learn more about the materials processes that we're experienced in working with on this page: https://www.sofeast.com/resources/mat... • And also, the products that we are expert in here: https://www.sofeast.com/resources/pro...
