Fastek, I just take every opportunity to point out the nonsense of lead-free. In today�s assembly environment the exempt military and hi-rel products are manufactured cheaper than lead-free consumer products. Now does this make any sense to you?

Yes, if cost is the concern. You can consider to try other alloys, like SCN from Nihon or SCS from Singapore Asahi, cost is definitely cheaper than SAC and SACX. I think the price is around 15~20 USD per Kg.

Maybe much more detailed than you have available but do you know the exact prepreg number you were using in the failed units? That is one of the only similarities I have been able to isolate on my parts - I am curious if it may be the same. Thanks,

I'm not sure what it was. It would be tough information to get as it's an old issue and sore spot with our supplier. I'm not even sure if we use them anymore for these boards.

It is a flattening machine used in the application of solid solder deposits. Basically a conveyorized oven with a press at the end. mk

Because our method for providing power to the stick feeders is clunky and temporary and with FES carts we want it out of the high traffic area.

Yeah, we've tried that and keep getting an error stating that an impossible location has been specified (can't remember the actually wording). Right now we just move them to the back and change the feeder assignments but it definitely hoses up the op

I would like to know, if the solder paste for SMT is unpacked (the syringe is opened) and is stocked at room temperature, then when I should trash it. After 12 hours/24 hours exposure? Or any other suggested time? Thanks.
