Has anyone experienced problems lately with excess flux residue left on the board after reflow when using Alpha UP78 OSP paste? We are getting a component failure that the designers are blaming on too much residue. Thanks

Nope, haven't heard anything. I'd check your reflow profile, contact Alpha. Also, UP78 is a very old solderpaste product. I would consider switching to one of their newer products.
