I'm guessing... it's for NATURAL color.

Subject: [BULK] - [DC] Board Spec


Hello Tech Netters

We have a customer spec for a board that says: GFN0620

I know it's FR4 (GF=Glass Fiber) and the thickness is .062 (0620)
But, what does the "N" designate?

As a side note, what IPC Spec covers these definitions? (not in 600 or
6012)

Thanks

Tom
