Over the past two years, we have
been seeing some really innovative and high Tech PCB layouts. One case in general, was a Board Design that
incorporated multiple ventilation tunnels within the layer structure of a Board
on Board application. What is Board on
board? The application was to mount 4
pieces of laminate together, with ventilation tunnels, over the top of a Double
sided Board without air leakage between the layers. Our biggest obstacle was to figure out how
not to fill the vent tunnels with pre-preg during the lamination process. After reviewing this Design, our staff came
up with a process to laminate the two Boards together with a few uncommon
processes. Below you can view a cross
section of the ventilation Tunnel through the layer structure, as well as the
Board on Board view.
