The caution with laser singulation is that the laser will carbonize the FR-4 along the edge. That is not a concern so long as the copper does not come out into that area. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Steve Gregory Sent: Tuesday, December 31, 2013 9:00 AM To: [log in to unmask] Subject: Re: [TN] super fine score cuts Morning Guy, Wow! 1.24 mil score! I wonder how that was done? Laser? Water-jet? Here's the pictures: http://stevezeva.homestead.com/micro_v-score.jpg http://stevezeva.homestead.com/panel_edge_230x.jpg From the panel edge photo, it looks like there's no "V" relief to allow for any sort of real singulation in the conventional way that you use a V-score.

They have the finest little score cuts I have ever seen. Each one has a tiny embedded device. I am afraid to break them apart. Wondering if you can post the pictures, and if you or anyone on Technet has a good idea for how to singlulate the boards.
