Hi, I need to replace a LGA component from assembled boards. What are the best methods (automated ones preferred) for this process? The main issue is how to apply solder paste for the fine pitch (0.4mm) on assembled board. Thanks, Eliran Ave

What is the best way to clean a bad print on a board of no-clean paste? We have tried a few different ways but always seem to get left over solder balls
