Hi Ed,
Try to get a sample done by LPKF.

Better lasers / much cleaner cut.
Ahne.

Subject: [TN] Laser depanelization
Hi all,
One of our aerospace customers is requesting boards depanelized from
support
frames.
I looked into router, but the conformal coating tends to smear and will be
a
significant FOD issue later.
We are willing to invest in laser, however, the result is a bit of
charring
on the edge, not much of a surprise. Unfortunately, this example
http://stevezeva.homestead.com/Capture.JPG was rejected on IPC-A-610-Rev E
Para. 10.7.4 "Solder Mask Coating-Discoloration" "Burned or charred solder
mask material.
In my opinion, this is not within the "spirit of the law" since there are
no
specific provisions for laser depanelization, only marking.
Anyone know of some way around this?
