Loose fibers would define frayed.
The photograph clearly showes loose fibers.
Therefore the boards are rejected as per IPC 600F- class 1,2,3 non
conformance, "frayed" with loose burrs.

Subject: [IPC-600-6012] Nonconforming Condition for Nonmetallic Burrs?


Hi All,


Got an issue here raised by one of our IPC-A-600F users.  The attached .pdf
contains a photograph that shows the board edge of a sample which the user
believes does not pass the criteria established in section 2.1.1.1.,
Nonmetallic Burrs.  It would appear as though the router had some problems
on the edges and fiberglass fibers are now falling off the edges.

Does this provide sufficient information in order to obtain a consensus from
this group on the pass/fail issue?


Best Regards,
