HI all, I need some guidence on deciding PCB thickness for 18" X 12" board. Since there is not much requirements on No.of routing layers & power layers, i am more considerable to the mechanical aspects of the board (like warpage,aspect ratio,etc.,). can some point me the recommended pcb thickness for proposed pcb size or vice versa? Where can i get those information?
