We have recently had problems with bare boards coming in too thick. I would like to know how to properly specify the minimum and maximum thickness using the 13949F and IPC 4101 specs. (We currently use "MATERIAL: GFN 0620 C1/C1 A2A per MIL - P - 1394

Was this a lead-free capable material that fits into IPC 4101/126 or /129, like an Isola 370HR? I would not be surprised because from the picture I think I can see resin underneath the lifted copper, which is an interlaminate separate. This is a
