If a OEM does the wrong thing tell the World. Tell every single person you know. But also do the right thing by them when they do the right thing. Tell the World. If it's right it's right. UIC seems to be doing the right thing right now. Their regist

Does anyone have any recommendations on how to track feeder maintenance on fuji CP feeders in a contract shop ? We are constantly setting up and tearing down feeders. Some feeders may be getting picked out of way more than others. How does one keep f

Hello, Understand you have problem of cleaning adhesives from Dek Pump Print stencil. Well, we have a cleaning machine which able to clean solder paste and adhesives. And also, we are not using any chemical but use water-base detergent. We had few c

Dave, Are you using The DEK plastic stencils with the 3906 or stainless steel? When we were using stainless steel, just about anything worked. It seems that the process for cleaning these *%#*&@" plastic stencils is either the best kept secret in

Interesting. From the reaction we got from DEK, I thought we were the only ones with pumpprint woes. We've tried 1 stencil with Bioact SC10, Hydrex SP&WS, Axarel, and Loctite remover on both Heraeus and Loctite glues. Some we spray, some we work-in m

I am not sure about the way the board is made, but I am sure that if you change your handling system to a tray based board handling system you will reduce these problems to a manageable level. Tray carts and trays are clearly the industry standard m

I need help understanding your problem. * What�s the difference between �e-test failure� and �total failure�? * Why do you think that an ESD induced failure would only be a �total failure�? * What if this is caused by a cracked solder connection? Yo
