Thanks Dave, I will be sticking with Manufacturing Engineering. These are good guidelines but what is standard clearance for various packages? This is a dimension we usually seek by eye, whether we will have a problem or not. We use straight DI -

Mild tombstoning on 1206 Kingbright LED. Has anyone seen this problem and have any suggestions in root cause? Please see attachment for more detail

The problem is occuring on more than one part # of our 0402 components. That is why I am looking at the reflow oven process very closely.

We use immersion tin boards and ENIG with Sn63Pb37 with no problems. We did have to tweak the profile higher with ImmSn though.

Isn't that the non-eutectic one that provides the pasty phase range that people use to clobber their tombstoning problems?

If you're having trouble with a specific board, double check your Pattern, Diameter, Color and Scan Area under the 'Mark Data' tab. You can also try setting the Pitch Tolerance to '0' in the machine configuration. Good Luck, Bill

When our IP-II did strange things we would do a reset start. This fixed a lot of odd behavior. Jerry

All I can say is my regular "Get it analyzed", so you'll know what the streak is. Regards, Vladimir

Wise move :-) Please let me know the results of the analysis and we can take it from there. Vlad

I used a Balston in another life. It wasn't large enough to provide for reflow or wave but they made them large enough. Maintenance was minimal, problems were virtually nonexistant, and like MikeS implies, the airflow requirements are substantial.
