Our metal core boards are v-score, I have never had mousebites suggested to me for metal core and I'm not sure how the nibbler would like it.

Good Morning all,

We're about to build a MCPCB (Metal Core) and I'm having a little issue
about panelizing it. It's a little teardrop shaped board about 1.5" wide by
3.5" long. So I did a panel drawing for the board shop to panelize this for
me:

I have one board shop telling me that the v-score is the best way to go as
far as being able to depanelize it after building it, and I have another
board shop telling me that a tab routed mousebite is the way to go because
a v-score will make the panel too flimsy. So what is your take on it? The
board has doubl sided SMT

I've built metal core boards before at a past employer but they weren't
panelized, so I'm not quite sure how stable it might be with a v-score, or
how difficult it would be to singulate with a mousebite. Also we do almost
all of our depaneling here manually, we don't have anything but a foot
operated pneumatic tab nibbler.

Any input is appreciated,

Steve
