Instead of using adhesives to glue the back side SMD components and wave soldering them together with the through hole components, our manufacturing engineers choose to process the back side components through reflow oven without adhesives and proces

Hi T, Gluing parts to the back side for wave solder is a widely used process. Running waves pallets is probably the last way I would want to run a wave. There are just so many things that have to be done to assure good quality first time pass, tha
