> I have a 3.5" x 5.5", .063" thick board we will be building in
> somewhat high
> quantities (3,000+/month). This size board is just on the edge as far as

> through the cleaner with no problem. I do not have a lot of experience in
> the best designs for panels. What are the advantages/disadvantages between
> v-score and tabs? If using tabs, how many are required to maintain the
> rigidity of the panel during reflow? Does there have to be a border around
> the boards? Are fiducials required on the panel in addition to
