I'm curious to know what the pitch of the outer pads is/was on your device. Also, is this a general formula you use on all of your QFN devices or was this for one specific device?

We'd add poor thermal recipe development, focusing on some QPF but not others that may a have a peculiar plating that requires extended time above liquidus.

Steve: In comparing TP9 with Topaz, what consideration did you give to tear-down / set-up time?

It was apparent to me that because he was looking at a Topaz, not a Topaz X, and a TP, not a My9, that he's looking at older used machines. Is there a used Sony in a similar price range to the other two that will outperform them?

Be aware that there is a significant difference between TP9 2U's and TP9 UFP's.

I have some alternatives that match up well spec wise with these two models. They are factory refurbished machines priced for quick sale. Contact me if you would like more info. Greg
