Kathy, The contamination is coming from the solder process. Most feel that it came from the HASL process and was left behind, following its way to the assembly process. There are large amounts of chloride and bromide left on the boards. The kicker is what we are finding out is that it is just not one product. It looks as though it's affected all the products that this co. has manufactured for us. Some of the products are still on the shelf in a warehouse, in there original packaging from the assembly house. I have been able to look over a few of these assembly's and they look to have trace amounts of contamination in different locations. Regards, Ted <snip> >Where is the contamination coming >from?
