Can anyone comment on the pro's and con's of Ekra's E5-36 stencil printer? Has there been an industry review written for this particular model?

The Systronic machine uses spray technology. I recommend that you read the following thread regarding the potential damage caused by spray stencil cleaners. http://www.smtnet.com//forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=10557&#Mess

I agree with Steve on this. If you just order the stencil you would probably save more money than have to fix the boards if you were to do it manually. Most stencil houses for new accounts will let you get a free sample screen as an evaluation.

I've cut component patterns out of old stencils. Not as good as buying a new mini stencil but still it worked. I guess you can't buy those pre-pasted boards? I've never tried them but they look interesting.

I have used a 10% area reduction with home plates on 6 mil stencils with good success. If you're using 5 mil stencils you might go with 0 or 5% reduction.

Volume req'd for pih is 2.2 x the hole volume after lead has been inserted. Stencils work quite well in PIH applications too if you can make aperture large enough. Slow squeegee speeds also aid in filling hole with paste. Russ

Your DEK could read non-blackened fids? Wow, you must have bought them from Superman. Or did you just teach baord pads and stencil openings?

The E5s I had just needed the fids to be burned black. Never needed epoxy, although we did have one stencil that we had to touch up with a sharpie now and then because they didn't burn it dark enough (too hot...?).

Probably because you are using baords, as you quoted above. "Your DEK could read non-blackened fids? Wow, you must have bought them from Superman. Or did you just teach baord pads and stencil openings?" In my DEKs, we use the new fangled "Boards"
