I have two questions that maybe someone can answer? 1. Can or should lead free components be used with standard 63/37 processes? including sn/pb pcb's? 2. Can or should sn/pb components be used for lead free process? I have recieved mixed feeling

The solder adheres to the lands very well so i don't think that problem is with solderability of the PCB. Not wetting to the 0805 terminations. When the problem appeared with the 0805 we chenged the supplier. But there was commnon element Pb-free te

You will need to preheat the boards for a lead free selective solder process. A preheat module is critical for any wave or selective solder process, if you don't get the board preheated properly the solder is going to resist flowing to the top of the
