Thanks. From what I can see I'm looking at right around $120K for a new, reasonably equipped model. Damn.

Thanks for all the info guys. The biggest issue I have on cleaning is under QFNs and the like. But even an 0805 or 0603 will give us trouble now and again. Like I said, our current system isn't making me happy. It's looking like Electrovert is the wi

I'm not sure. I'm working through a contact that just happened to know of this one, and knew I was looking.

thanks for your inputs,but what i meant was that a connector component beside the BGA for repair has some flux residue on its leads after baking, the BGA was Ok. we are wondering why this happened...pls enlightened us.

Thank you very much for your reply, we'll try to perform your advice. I'll feedback you soon for the results. 'till then...

Flux is fine, make sure you have one that will withstand the extended and hotter reflow for the Lead free, your paste MFGR will most likely have the flux formula in their paste available as a tacky or paste flux Russ

If you are using VOC free flux, then forced convection preheats are better at evaporating the water. That may be why you're getting the "splatter". Plus, forced convection preheaters are most efficient at thermal transfer. See if you can get one to p

Thank you for your input. Indeed, I am using a VOC free waterbased flux.

Are you using Houdini brand paste? It really depends on the part and pad size, but I kinda doubt that you�re paste is disappearing during the 2nd reflow. Do a side by side comparison of first pass versus second pass reflow and show your operator.

yeah, that's what I've explained to them is that it is not going to disappear. Currently they are in the process of running this PCB again and I'm going to do the side by side comparison. Thanks for the input.
