I've seen some hazing due to moisture, have baked those boards and been able to remove the hazing affect. We never lost adhesion are you seeing any adhesion loss? Kat -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of John Parsons Sent: Friday, March 30, 2007 3:13 PM To: [log in to unmask] Subject: [TN] UV Bump Happy Friday! I am having a conversation with an industry peer and the conversation has led to the following question; "I am not aware of any other ionic cleanliness specs for this board. The reason our customer is looking for UV bump is that they feel that during assembly UV bumped boards would not experience white hazing issues. They are having some issues with their assembly house in regard to white hazing. Is UV bumping a solution to problems with white hazing that occur during the wave soldering process?" I don't have an answer for her. Can anyone provide me with some insight here?
