Harry,I know what you mean. You are completely right and justified. My father owns his own business and I see stuff like what you described all of the time. Yes we have done business before. I worked with you when you were with MPM and after you st

I'll put a vote on MyData, but you might have problems with the volume... If you're buying used on this better off buying from MyData, they have a tendency to buy up the decent stuff off the used market, and anything left noone really wants to deal w

We finally can't avoid adding wave solder to our process anymore. For lead-free, medium sized wave I'm leaning towards mid 2000s senju units as the best fit. I've never run their equipment. Opinions? As a point of reference for our general capabilit

Daxman, Try this: - it might help your histogram. The camera may be operating production reads at or close to the z-axis drive limit but you don't know really. Write a dummy program that will allow you to load a PCB into the centernest at vision h

Bruce I�m with yall. Designers and fabricators say �pins�. You say: * BGA pins are 1mm [0.039�] pitch. * BGA pads are 0.4mm [0.0157�] diameter. * BGA pins are 0.6 mm [0.024�] side-to-side. * Board thickness is ~0.4 mm [0.015�] First, as you can

99% good solder joints = 10000 ppm (defects per million opportunities). Having only built with 0603s I can't speak for a target but that still seems pretty harsh....with a 75/25 0805/0603 ratio at my last place of employment I think we were running

Worked for MPM for many years, and this sounds like a fairly common problem which is easy to fix if you can answer a few questions, several of them already asked... 1. Is this happening only on this board (if the answer is yes, this is a good thing!

A couple years back we were looking at going to an enclosed solder paste printing process, similar to the ProFlow, Crossflow, or Rheometric Pump. We have older MPM AP25's with a custom transport. Speedline told us that in order to add the RheoPump,
