Bev, How did it look in the SEM (the contrast)? Vladimir ------Original Message------ From: Bev Christian Sender: TechNet To: [log in to unmask] ReplyTo: TechNet E-Mail Forum ReplyTo: Bev Christian Sent: Feb 26, 2009 10:51 Subject: [TN] Weird one - bismuth in overmold TechNetters, In checking a component for one thing or another we found via SEM/EDX particles of bismuth in the overmold. Smaller amounts of bromine were also found in the same spots but the largest signal by far was due to Bi. I have never seen or heard of such a thing before. Can anyone shed any light on this before I go to the component vendor?
