We use the exact same method Chunks outlined for evaluating just about anything we're going to roll out worldwide, whether it's a material or a machine. List your factors (print speed, solder spread, etc), assign each a weight, evaluate each paste a

"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

J-STD-001 doesn't necessarily require additional controls under conditions of low humidity, only that you verify the effectiveness of what you have in place. ESD S20.20 [1999] only says that relative humidity above 30% is "desirable". ESD S20.20 [200

Although we do not have any soldering issues with our OSP PCB's, I am trying to establish clear rules with regards pcb storage and shelf life. Our PCB's are supplied in metalised moisture barrier bags but without desicant, our current rules as follow

Prob totally screwed the pooch... Got more than a little frustrated with not being able to get the stupid software to do what I thought it should do, anyway figured maybe the IEC port was the problem - I have a couple of spare cpu cards, so I swapped

No idea, could be a weird translation error, but its certainly something I have seen . For an FLX they just ask for this "5-6 bar, clean, dry, oil free, filtered 2 µm, connection diameter 8 mm", 40litre/min Personally I would go with a mo

Excuse me seeming to parrot Wolfgang�s posting, but he makes good points and I'd like to expand on them. I disagree that it's about disliking a "non-techie to post a reply/comment to the SMTNet forums." It's not about WHO posts. It's about WHAT i

| Hey Ya'll! | | Have any of you ever worked with one of V-Tek's "Economax" tape and reel machines? The biggest thing I'm curious about is the type of cover tape that these machines use. It's something they call P.S.A. (Pressure Sensitive Adhesive)c

NO-LEAD COMPONENTS WITH LEAD SOLDER ISSUE: We agree with Russ. We've dicussed this several times on SMTnet. For instance, look here http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=25394 LEAD COMPONENTS WITH NO-LEAD SOLDER ISSUE: We disa

On your last point, Wolfgang, I agree big time. Not that I disagee with the rest, but it's pretty much all been said. The layout of the forum is showy, which is OK by me as long as they've got the hardware to support it. Unfortunately they don't, a
