A process consists of much more than just thee machine. When developing a cause and effect diagram ffor the process, there are many parameters that fall outside the machine itself. There are Man, Machine, Methods, and Materials. Just monitoring th

You can put a 15, 32, 45, 54 mm lens on a Topaz. However, the 54mm has no published specs. Standard config would use the 45fov single cam. Remember the larger the fov the lower the resolution. Oh and for you guys out there who like the parts per

I agree with all the prior postings! But I have some additional thoughts about this. If there is a build up of moistures (% humidity) inside the pcb; before you reflow the pcba; then you will have the result out of the oven, just as you described. My

This problem is not unique to China. Second user customers are always challenged to assess machine condition, upgradeability, service history etc. More often then not, candidate machines are located halfway around the world. Further complicating thi

All good advise, guys. I somewhat blame myself, that I didn�t inspect the machine. On the other hand, who knows, what machine I would have seen. Here are some e-mail responses, indicating, that this is not the type of business I�m capable of doing my

I�ve seen new table-top machines for $ 15,000 at exhibitions, but only one time and the same vendor didn�t show up the next time. Realistically, new machines capable of doing 0402 and 20 mil and a few kpph under $ 15,000 do not exist. Any used mach

Thanks for the replies. Interesting white paper. Didn't quite answer my concerns but still a good read. I was actually surprised that to test temperature uniformity across the zone, they attached T/C's to the substrate rather than measure the ai

hi Steve/Pete, Thank for your email to affirming our current mounting and soldering flow! In fact, I also don't see any problem for the pilot run(though in small volume - 500pcs). However, the problem is - I am challenged by my customer that the AI

You did not tell us where your boards fit on the thermal mass range. That is key. I've run Pb Free low to medium thermal mass boards with good results on a 5 zone oven (5 top/5 bottom). You should not have a problem running a medium thermal mass boa

Hi Greg, We've used lots of machines over the years & seen lots of different tape related issues - the main one being snap off of the cover tape, usually due to too much glue, over entusiastic heat seal, or a feeder requiring maintainance. Also the
