I have experienced tombstone with one brand of 0603 capacitor. Swapping in another brand (actually two different brands to date) has stopped the tombstone. I have measured the parts (length, width and height). There does not appear to be any apprecia

What machine are you using to place the components? I assume that you have checked placement prior to the refow process?

Mike: I'm with you. The only variable is the component. Look for corrosion, uneven plating, or crud on one of the end-caps. Good luck. Dave F

Thanks to all who responded. I am tending to believe oxidation is the root cause. I will be contacting the supplier to get definitive answer. Mike

I have seen this before, our problem was palladium termination of this component. We could not change suppliers so we use a "reverse homeplate" stencil design to put the majority of paste directly underneath the solder terminations of the component
