WE LOOKED INTO THE YESTECH AND THE MIRTECH. TODAY WE ARE INSTALLING OUR NEW MIRTECH AOI MACHINE. WE CHOSE THIS MACHINE OVER THE YESTECH BECAUSE OF IT'S OFFERINGS. THE YESTECH WAS A CLOSE SECOND. I WILL POST LATER ON THE PROGRAMMING, THEY ARE ALL

Thanks for posting this Patrick. My head has finally stopped spinning after reading that document. Unbelievable is all I can say.

Anyone think that this, http://img336.imageshack.us/my.php?image=nodule27wc.jpg, is a nodule which will eventually grow into a tin whisker? Observe the plating on the component lead. Thanks in advanced for opinions.

H, I tried without the commaat the end http://img336.imageshack.us/my.php?image=nodule27wc.jpg Seems to work. IMO, it looks like questionable component plating and not this so-called "nodule".

This sure doesn't look very healthy. The important things to know are A) You see this already right after reflow B) Is this showing up after the board has been in use for a while If you could answer these questions we could take it a step further. P

Patrick: The image that you see was from a unit that was known to have gone through a 5-year environmental life test. However, we took another board, pre-refow, and scoped a similar device. It exhibited the same grainy component plating.

Paul, The paste you use is another variable. As Pete recommends to know the real answer you need a DoE. Jerry
