I would consider this to be non conforming product.

Here's an image for discussion... The areas between the traces are not
bonded at all. I'm not going to register my opinion, but am interested
in the opinions of others on the acceptability of this flex. For
background, it has a single layer of metallization, and uses an acrylic
adhesive.

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
