KK,
Give me a call or e-mail off line. I have made fixtures like this for a
couple of my customers and I might be able to modify the designs to meet
your needs.

Subject: [TN] Zero Margin PWB Assembly Depaneling
>Dear Technetters,
>
>We are designing a panel layout for a small PWB assembly (1.6" x 2") which
>has through-hole components mounted very close to the board edge, leaving
>no margin for our usual depaneling process. We usually pre-score the board
>and depanel with rotary-blade type splitter. We considered hand-splitting
>in this case but we worry about cracking the SMD's on the bottom. Can
>somebody enlighten me if there are any methods, tools or equipment for
>depaneling in this case?
>
>For your information, the PWB material is FR2, single-sided, 1mm or 1.6mm
>thick. Topside is all though-hole devices of 18mm max. height. Bottom side
>is all SMD's of 1.2mm min. clearance to the board edge.
>
>Thanks!
