Dan: Until I got deep into development of a vacuum assisted moisture removal process, I always thought that the bake process would be saddled by the lack of atmosphere in the chamber. I later learned that the conduction of temperature at reduced atm

Because BGA's are so hard to rework, you'll want the maximum process window for your reflow equipment, and this includes an inert atmosphere. But as long as solderability and temperature profile are well controlled you can have perfect results with a

hi all. I am looking for a oven which can cure the conformal coating providing heat and the humid atmosphere. I am looking for a temperature range of 60 deg C to 80 deg C and a humidity range of around 80%. Can anybody refer to me the right vendors

Hi! I recently remarked on a thread that so-called VOC-free fluxes weren't. As a result, I got three private e-mails asking what I meant. As this seems to be unclear, I'm starting a new thread with my explanation, rather than sending out the answers

There must be discussions about this on SMTnet but I have yet to find them. I would like to hear from all you smart people about running LF and PB BGA�s on the same board using 63/37 solder. If you run your profile up to peak at around 225C +/- (nitr

I am testing some BGA's (PBGA 30mm x 30mm) to evaluate the maximum ramp rate we can achieve in our reflow oven. Temperature is being measured at the body(top) of the component / not leads. After several trials (with various oven settings), the high
