[RE-wrenches] Cell Cracks

[Jay]

I had a module engineer tell me these are often a static discharge issue which happens during the lamination process. 
It’s not effecting the cell surface but the encapsulate above it. 
It’s not cracking but it looks like it.

Has anyone seen this, and are these possibly dangerous (hot spots) or is this nothing to worry about?  An Infrared camera did not show any issues.
