Why would anyone want to underfill twice? Don't know. Was the initial underfill insufficient? This would be my guess. If so, isn't a second underfill a band-aid rather than a permanent solution to the problem? Yes What new problems would the second underfill cause? That is WHY I asked the question! :) Bev From: Karen Tellefsen [mailto:[log in to unmask]] Sent: Monday, August 23, 2010 11:25 AM To: TechNet E-Mail Forum; Bev Christian Subject: Re: [TN] Double underfill Why would anyone want to underfill twice?

What would be your comments be if a process group told you that they had underfilled a component and it was cured and they wanted to add more underfill to the component?
