We have 2 Mydata machines. Accuracy is closer to 25microns at 3 sigma and you'll be lucky to get a quarter of the 20K placement rate. Their flexibility is their selling point and are prefectly suited for high mix - low/med volume. I wish your high vo

You might want to check with Six Sigma Services, they do this for a living, and might shed some light on the process. Myself, I'm comfortable re-balling a BGA, but I don't know about re-attaching columns...here's their web page: http://www.sixsigmas

For a not-so-technical solution, we have a few customers that are using a Maytag "SkyBox". Available from Home Depot. Like a small soda vending machine, but allows you to control the dispensing. Sincerely, Mario Scalzo-CSMTPE, Dartmouth 6 Sigma G

The final reflow profile really depends on which of the components are Pb-Free (such as BGA's) and the lowest temperature limit of the components. I'd be glad to share with you some ideas for solving your particular issue. Please contact me offline

Kester R562 is listed as an ORH0, a high activity flux, not sure switching pastes would gain much. What is the finish on the leads? How old are the parts? You could have the parts reconditioned (SixSigma, Corfin, ...others) but this can get costly

Hello SMT people. New member - first post.... "Have you considered a refurbished SMTech Benchmark printer from SigmaPrint?" I tried that. The reply I received stated that they hadn't had any for years (despite showing them as available on the site
