With LeadFree coming, I'm trying to find out what is the best all around finish requirement to put on my fab drawing.
My boards have a 50mil pitch BGA. The soic's down to .4mm pitch. Matte tin, ENIG ?? I imagine Matte tin would be the cheapest. Also, with the extra heat needed in reflow, will FR4 be ok? Any help will be appreciated. tr :) This message and any file transmitted with it may contain confidential information and is exempt from disclosure under applicable law.
