We use Samsung and our 24mm feeders have 8,12,16,and 20mm pitch settings. I have found 20mm pitch quite common. My favorite is yhe 12 on 12 our feeders don't support that, we have to put them up on 16mm feeders our cycle them 3 times on a 4mm pitch

WE ARE USING MIRAE MX240. ON THIS MACHINE, THE FEEDER ADVANCE AND THE FEEDER PITCH IS CONTROLLED BY THE MACHINE/SOFTWARE AS OPPOSED TO THE FEEDER ITSELF. OUR SELECTIONS FOR 24MM FDDERS ARE 4,8,12, 16, AND 24MM.I WAS WONDERING IF THE 20MM PITCH WAS UN

It's been a while but I believe we did this and it'll work (misspicks WILL go up though). I would make a quick test program and pick 50 or so parts from a feeder and place on a board with sticky tape. Placement won't really be the issue, just pick up

I agree with stand-alone as well. We're a CM and have three AOI's, we keep them all stand-alone. We use them for paste inspection, first articles off SMT equipment, QC articles from SMT, hand assembly QC, TH first article and TH QC. We treat AOI as

Dave, Few questions concerning your Umiseal 1B73. To cure your Acrylic coating do you respect specification ( 2Hrs-170degree F) or you go faster than that? What do you use to cure it? Do you have to clean your nozzles each day or each monday beca

I would be willing to bet that you are ramping up way too fast and possibly too hot/long of a soak and killing your flux activity. this will give the appearance of "no reflow" due to non-coalescence of the solder balls. check this board with the hel

Hi, The normal electronic components you purchase should have lead free variants. Also, all solder paste manufacturers have lead free solder pastes, so you just need to get the paste specification, and then re-profile your oven for it. Temps are hig

Currently, we see lead-free solderballs on BGA. The issue for us is determining the reliability of these components when using leaded solder. Most solder materials manufacturers supply lead-free solder balls. Check with your current solder paste s

My current company used to manufacturer the electronics for coin star. That aside...if you have no intent to sell in Europe you are not affected. But imagine if you (Coin Star)are approached by Europe's largest retailer for 5,000 Kiosks. "Oh", the
