Chris,

I can see the potential for conflict as we say no soda strawing.  however, I would apply the 25% "nonlamination" limit to the soda strawing.

My two cents.

Hi all,

A customer has ask me to query the group about coverlayer sodastrawing.

From the applicable paragraphs in 6013 and 600, one could interpret sodastrawing as completely unacceptable unless it is a "nonlamination" , in which case it can reduce dielectric spacing by 25%.
Unfortunately there appears to be a disagreement about whether sodastrawing is to be included as a nonlamination.

Thanks,
Chris
