Hi Technet, I have a question for those that are involved with component
manufacturing.

What type of flux is used for preparing leads for tinning? Also is there
anywhere that chlorine is used in this process? Where would chlorine come
from if not from the manufacture?

We analyzed some of our raw goods with a SEM and noticed that there was
chlorine present in the junction of diodes and also on the leads by the
glass / slug interface

Thanks
Jason
