Hi Vlad - Nope, based on the huge amount of testing of products for RoHS 
materials, it is amazing on how much "mummy dust" is incorporated into 
products for specific reasons.

Re: [TN] Weird one - bismuth in overmold






Dave,

Are you saying that Pb in the overmold wouldn't be that surprising? :-)

Hi Bev - hey, Bismuth and Lead shell lines overlap each other in the 
0-10kV range but are distinctly separate in the 10-20kV range. Which range 

did you use? Could you have a case of mistaken identity?

[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?
