I am looking to discuss 0402 issues, specifically tombstoning/unsoldered. Any recommendations on pad size/spacing, stencil design etc would be helpful. Placement and reflow profile look good.

I'm hoping to use 0201 caps and resistors in a new design but so far have only found one company who makes such small devices (Murato). Can anyone direct me to any other supplier? Are there any particular problems associated with using such small

Hi Mark, This problem can be overcome by adjusting the camera brightness - Gain & Offset. I think the offset value is very high. Try reducing it.

That also allows a channel for degassing and also breaks up paste into sections that tend to balance the forces acting on the part. So basically window paning is even better than you might think.

We are trying to solder a Surface mount relay having lead free finish on the leads. The leads are not getting soldered down during the reflow. The leads also look oxidized (failed our solderability test) but we don't have an option but to use these r

Steve: Try to find something that�s common to all your skewed parts. We haven�t had much trouble with it except for some MELF diodes a couple of years ago which didn�t look well aligned but made no trouble with specs. Better suited pad design solved
