Hi all, I thought I'd use this forum to ask a couple general questions on fluxes for manual operations: First - Is it OK to use a wave soldering type flux (specifically OA)? Thinking about activation temperatures and the ramp rate of the wave solder

You pretty much hit the nail on the head Chrys. Reed runs a lot of exhibitions for a lot of different industries, and they do very well for themselves, probably too well. Right after InterNepcon Japan '96, the major equipment suppliers in Japan got

They are supposed to be production parts. Our volumes are in the hundreds due to rapid change though. Jim Nunns | Just a comment: we've seen PBGAs curl up at the corners, but only on prototype components that came off of a low-volume "prototype"

We have evaluated using WS-629 and our feelings are that the formula is not very stable. One evaluation showed great results; superior solder joint appearance and good printability. The paste would not roll on another evaluation nor would it release

How is everybody? I was asked about any problems that would be associated with having a plastic casing injection molded around an assembled PCB. I am not sure if injection molded plastic has to be hot, I am assuming so (can they use epoxies?).

For process management with SPC of the stencil printing process with a fully automatic stencil printer, what process outpur parameter would you recommend for SPC? It appears to me that there are two options: A: to have a pn chart based upon the % of
