If the PWB is flat on one side, I would use a good Xacto blade and a paper cutter of the type that slides, not the type that shears. By placing the stop exactly .25" past the blade, you should be able to lightly score the line two or three times until it cuts through each .25" strip. After you get the 12 strips of 12, cut them crosswise using the same paper cutter until they are all singulated.

Subject: [TN] super fine score cuts

Hi Steve,
We have a 3 inch square panel of 144 little boards. 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. 

Thanks,
Guy
