If you're looking to know the differences between the Reflow Soldering and wave soldering then this post is for you!
Reflow soldering experiments of IGBT modules were conducted to examine the shape of the lower surface of the baseplate before and after the soldering process, and are used to verify the modeling results. The model shows a good agreement with the experimental with an error of 5.46%. The FE ...
For the soldering process, the workpiece W is fixedly retained by, e.g., a jig not shown at a predetermined work position on a support not shown. [0045] The instant that the control unit 14 accepts an activation control signal DC (H-level) from an external device not shown, it ...

Apart from pad or component lead oxidation, poor wetting during reflow can result from excessive oxidation of solder powder during the soldering process. Improvements can be achieved by reducing the amount of heat absorbed by the solder paste during pre-heating. Ideally, the reflow time should be...
But, of course, there’s a catch with the “Double-Sided Reflow Soldering” process—it requires two trips through the reflow oven, bringing about some process limitations. A common challenge is that, when the board revisits the reflow oven for the second time, components on the first side...
