Ya I agree with Dean. We've done quite a lot of work with the SRT Summit2000 rework station.The results have been satisfactory, to say the least. One should however characterize the different operating parameters:namely the working scavenger air flow

At the wave, you should collect data on the critical process parameters. The cliche being, it's better to control your process via SPC versus performing SPC on defect data. Perform a DoE to determine which variable interactions have the greatest eff

Our NPI division is in a same category. We assemble small quantities and lot of different set-ups. I created a DPMO charting method using Excel that we use at Post Reflow, Post Wave and Final QC. In addition, we use x-r charts at screen print for con

George: There is no industry standard for the calculation of process capability. Although, you should be aware of IPC-9850, Surface Mount Placement Equipment Characterization Actually, there is a grand bulk of discussion on process capability in t

Hi All! I've been reading this conversation which prompted me to break out the IPC-SM-786A from the IPC manuals from our parent company in Maryland sent us (we're just starting up in California). It's the Procedures for Characterizing and Handling of
