Yo! first, lemme ask whether you refer the problem to HTI service engineers ? What was their reply? Can't they help you? Well when I was with a certain company in Singapore, we got an HTI Semi-Automatic Printer...it was bought at about 1994 and it wa

Hi Willem, you may be better off to study the archives of Universities. I know that at least the Universities in Berlin, Munich and Georgia Tech here in Atlanta are studying the manufacturing process on SMT lines. I was once exposed to a quite compli

John, Depends on what you're cleaning (paste, adhesive, ink, etc..) and your process (do operators just dump a dirty stencil in and expect a clean one out, drying time, effect on the polyester). I could suggest a couple of name brand cleaners, but I

Andy, I have been "evaluating" some AOI systems. However, some of these are actually SAOI (Semi Automatic Optical Inspection), which is not a problem if that is what fits your process and budget. You can buy a high end system complete with many cam
