I think we are all on the same page with this one. Since you ran from 96 until now without any issue I'd say that now you know what causes the problem, make a note of it for next time and move on. I have found with our older machines that "if it ai

Hi, I had seen your post earlier but had lost my very old log on information. First I will say that BGAs should never be placed and re-flowed with a rework station unless there is absolutely no other option, so I don't understand why your assembly ho

We just designate shelves with signs, PULL HERE, Move UP NEXT, MOVE UP 2nd, MOVE UP 3rd, We also keep paste in the incoming case, if it has one until its time to open it. Our operators are the ones who stock it and as long as they know they own

Thanks guys. I can see the benefit as a CM, when you have no control over the Parts/PCBs that come in the back door. In my previous job at a CM I did often have product coming in the back door that did appear to have exceeded its shelf life, and hav

YesTech makes a pretty nice machine, the software is pretty simple to learn and use. My shop runs on average 3 or so new products a week, so quick and easy programming is a must. Most programs can be done in an hour, usually less, depending on how

Good morning everyone I have read postings about Mirtec AOI, but they're not recent, so I'd like to know something about your experiences with Mirtec Benchtop MV-3. Our inspection department has now 3 MV-2HTL and we tried to make them as useful as po

Head and Pillow defects beneath a BGA are difficult to find, no matter what the equipment is on hand. Since you do not appear to have access to tools that would help you, or $$ to purchase said tools, I might recommend that you use an outside source
