Hi All, There are IPC drafts in circulation IPC-1751, Generic Requirements for Declaration Process Management and IPC-1752, Materials Declaration Management. To me it looks like the regulations become more tolerable towards lead in solder Lead in s

500 rejected (?) per million placed components is a very good rate, considered that it would be better than 4 Sigma if you name it defects on the board. Or do I incorrectly convert ppm to dpm? * 3 Sigma 66,800 defects per one million opportuniti

In that the machine times out and waits for a feeder refill and doesn't just skip that part and leave the space empty, it's not a defect. I have found 500ppm *fairly* easily attained in SMT depending on the board mix and how you define (1) a defect,

I'm not a Mydata user, but I know some people who have used them for prototyping. They swear by them for flexibility. I was at Mydata over by Boston a few years ago, and they had a refurbed machine there for about $50,000. If I remember correctly,

Hi Rob, I've been using Quadras for many years and I find them very useful for prototyping and small batch productions. The software is very easy to use and you may import many CAD formats by an off-line software. The laser centering system is able t

Thanks Olas, I have some experience with these machines - not too impressed with the feeders though, but I will take another look. Hi VickT, Thanks, but no thanks, the Advantis is not what I am looking for - it is neither small, nor a low cost pro

Hi Greg, Thanks, I have looked at Essemtec CLM9000 - they look like the sort of thing I'm after, and to be honest I would have looked into it further but my experiences of being a Contax customer have been less than pleasing. I've nothing person

Hi all, I have a question to the users of the Topaz Xi machine. We currently are placing the electric capacitor (10.5 high) on the Topaz Xi (erlier we cut the nozzles 74). So the machine picks the component and placed. But there is small problem. Du

Any tried and true methods for tracking WIP with a paper system? A good white paper on the subject or even a decent book reference that covers the topic would be great. It's really never been done here before and beyond establishing time standards a
