Steve,

I'm with Mark, scoring of m/l is no problem if done correctly (had to put that in)

The guide I use is as follows:

        25% OF THE TOTAL BOARD THICKNESS FOR A WEB
(LESS IF YOU HAVE A SMALL BOARD - MORE FORCE REQUIRED SINCE LESS LEVERAGE)
                I USE 30 DEGREE CUTTERS - THEREFORE MINIMAL INTRUSION ON THE REAL-ESTATE OF
 THE PCB.


        De-paneling tools do work well - RADOLL springs to mind.

<<<BUT>>>

                My opinion is "If scoring is done correctly - you should have no need for this tool"

        Heavy/odd shaped boards are best handled with JUMP/4-axis scoring to the web suggested above.

For more info on my scoring thoughts, you can see the IPC EXPO PROCEEDING 1997 S10-5 for my & Ron Murdock of NLS's paper on the subject.

For further reading, Mark also wrote a paper.
