I don't have the boad yet. As this is a 4 layer board I'm not sure if has Via or not. The reason for post is that the AD9866 is expensive to ruin and the board may be a one of. I only have a cup warmer that was used in the past I'm not sure it can be used or not. I will try to find a square nozzle for the Hakko. Whats a good solder paste to use?
