Many component manufacturers are moving to Pb free terminations. I've been doing a literature study of Pb free processing and have found several articles that indicate Pb-free paste with Sn/Pb terminations leads to early fatigue failures. Does anyo

Inds, It's about time that lead-free components can stand higher temps "myth" stops. The only difference is the plating, the component itself has not changed. Can you give us an update on this threat? If you�re the same inds http://www.smtnet.com//

Hi Dave, Yes the lead was there before reflow. After reflow it has bent inside. The component was inspected before placement. We are unable to analyze, what might have went wrong. Regards, Ameen

From technical point of view: it should not be a problem to mix Pb with Pb Free components soldered with a LF solder process. You have to take care about the max temperature allowed on your Pb components and make sure they can withstand the higher

If that's the case, let your customer go. I have run into this situation recently. Q. Why do you not run a dedicated line for lead free? A. You (the customer) give less than 12 weeks forcast and expect us to have a dedicated line for your product?

Hi GS, Thanks for responding - looks like we already put end termination coating on the label - we just call it "second level interconnect" There is a specimen label at: http://www.anglia.com/quality/labels.pdf Regarding standardising labels accr

"The only real problem we're seeing is some suppliers trying to use bismuth. That's a big no-no in a SnPb process and we won't accept those parts." Yes and no. Since the SnPbBi tertiary alloy melts at 96 degC, any product rated for storage above tha

I would assume we are talking about a radial leaded electrolytic cap? We use Electronic grade RTV (Dow corning 3145). It sticks good and can be removed if necessary. It is also pliable so you don't have to worry about CTE or other stresses that may

We had one mechanical engineer from a certain customer telling us we had to crop components leads so they didn't protrude through the board, as they could then come in contact with the case as the board was flush. Had I have known then what I know
