No arguments there. I 100% agree that quality engineers can and do solve a lot of problems on the spot. I've nevern said "run an analysis as soon as you get a problem". The whole nine yard started with a solderability problem. In my previous product

We are changing from through-hole to SMT, wondering what pitch requirements would an 8 pin SOAC require for pick and place? We think that this would be our finest pitch part.

Has anyone had success using a DEK Proflow printhead with fine pitch components (~.2mm pitch). I have been told that squeegees are the way to go for fine pitch. What other major factors play a role in successfully printing fine pitch. Print speed,

What do you all do to fix coplanarity on fine pitch QFPs? I know that the best thing would be to send them back to the vender, but what about the when you gotta use them? Straightening by hand seems to be so time comsuming. Any better ways? Larry

hello guys ; we are using a fine pitch component(0.65mm) on a thick copper PCB (Cu = 90�m) ; in this case we notice that we are in the process'limits , because the different supplier of the PCB are not able to ensure a good stability of it's process

Thanks for the replies. I have just ordered the IPC Stencil Design Guidelines manual.

See if you can get a sample of Dek's Nano Protek. We use it on all our fine pitch stencils. I'd say it's kind of like car wax for the aperture walls. They operators really like it a bug me every day to order more if we run out.

0.5 if you use electroformed stencil or > 0.8 if you use laser cut. 2. Always use fresh paste 3. Uses the right printer parameters for your paste(for example Alpha likes fast release of the stencil from the board - in DEK this is called separation s

Hege, the Nano coating goes on the opposite of the squeegee side of the stencil. I don't know if the cleaning paper is able to remove it little by little with the time, but I never refreshed my stencils with Nano coating and they work just fine. How
