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.

Hey SWAG, any idea where that Nano Protek goes, that you have to replace it? (and I am not talking about polishing up wheels) Is it being scrubbed off of the stencil during the print process, and over time it must be replenished? Sorry a bit off top

I did have the problem where it got into my touch screen, and had to replace it. I agree, the seals leave much to be desired. I ordered something from Mcmaster to replace what they had, so far so good. And good luck on your search, If I run into m

I've used the DEK Vector Guard system in the past. We had three of them and we did alot of change overs. They held up really well and our stencil storage went from rack upon rack upon rack to a very small space. It was worth the money and the perf

Aperature layout on your stencil could be a root cause as well. Home plate design aperatures have cleared this issue up for me in the past. If it's a clean product, running through the wash may get rid of quite a few of them. Also check your IPC s

Perhaps a photo of the faults you are encountering might shed some light on the issue. I would think it would take some extremely poor paste handling or paste for the paste itself to be the root cause of what you seem to be describing. I would be inc

Most ceramic you'll see comes from Coors or Kyocera. Size of your substrate will vary according to the stencil / component that you're using. 3" by 3" should be sufficient for most applications. If you get them too small, you could have handling is

Hola, We are about to start building a new PCBA using a LGA, we have not used such components in the past, is there any recomendations you can provide me? I've found some articles saying that stencil thickness is the key, what is your experince usin

It is very hard to say by looking at picture(solder joint quality).Overall appearance looks good.If you think is not sufficient solder or meeting required standard, enlarge opening of connector on solder stencil. Make all conn. aperture square or in

Is this happening on a new product you just introduced to the factory? If so, then I would check stencil design. Many moons ago we had a similar issue and discovered we were applying too much paste on the chip parts. We changed to a homeplate desig
