In the consideration of PCB manufacturing and the process of assembly house, we want to array boards and add rails especially in small boards. But it depends on board sizes, shapes etc.
If there are no arrays from customer files, we will array by our standard way. It will be by V-cut or V-cut with tab routing. We will add tooling holes(0.158") x 4 places and fiducial marks(0.04") x 4 places at top/bottom each.
We want to get completed files arrayed by customers if possible.
