Slain, A melting point of 300C would be a little too high for the components and tinny boards. I just heard they will market the watches as Swiss "army" watches which makes them exempt.

Rob, How do you find the performance of the SACX ? Did you change the internal components of the Bath prior to changeover? aj...

Sorry I misled you. The PCB pads are wetting, but there is no fillet being formed. After reflow, it looks as though no paste was put down on the pads; however the paste print is fine. All other components solder real nice, it's only the Pd-Ag parts t

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".

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.

Hello EC, Thank you very much for the good input. I really appreciated. Our mounnters is Panasonic CM402,CM301. Do you have any suggestions/procedure how to reduce the sources of variance at each step of component placement process? regards,

Hello EC, We already done your suggestion but still no effect. Feeders already calibrated. Do have additional inputs for this? Also is the barcode eliminate 100% wrong value component? regards,
