Hello, 

  I'm wondering if someone had issue with copper on IC lead.  We had a batch
of IC where we find that on the side of the lead and at the front about 1/4
of the lead that have copper.  It's seem that the lead have been cut and
didn't get plated.  What do you think we shuold do to get a good solder
joint.  Because right now the solder stop where the copper begin.  We use a
no-clean paste.  Should we go to a more aggressive paste? like water solube?
shuold we change our profile?, we get a peak of 220celcius. 

Or anything else you have try?


Thanks You

Yannick Brisson
