Hi all.. Have a question relating to cooling a HOT 225-ball BGA. I tried to look in the archieves, but my search technique must be lacking or I am using the wrong "words". Can I use an "underfill" to help cool a hot BGA or is that the wrong term? I am considering using a thermally conductive, electrically insulating material under the part (3parts/assy), but have no hands-on experience with "what material, how do I apply it and what are the related war stories". Any help out there in TechNet land???? Thanks in advance, have a great day and a super/safe 4th holiday!!!!!!!!! Regards, Bob Vanech Bob Mango Computers Norwalk, Ct. (203) 857-4008 x 108
