I am currently reviewing an old board we have that has issues with
separation from the assembly panel... I would like to know what methods of
'singulation' you have tried and the measure of success you had with it...
I think many of us have encountered issues with assembly panel designs and
might be able to share the things that do and don't work with us...

Types of panels I am familiar with...

Routed edge with tabs
Tabs with mouse or rat bites
v-scoring
die punch and return
cracker boards

Which methods do you prefer and why?
Which methods to you avoid and why?
