Thanks Ramesh,
Is it possible to overdue the copper pour ?
I ask because I have a pcb using the second layer set, with ground pour on top and bottom and I seem to have emc problems. The pcb is a module with headers, which mates to a motherboard with sockets/recepticles.
Now it works on one motherboard, but doesn't work on the other one (maybe 1 out of every 20 attempts it actually works).
I have a pcb module from another company with the same pinout and it works on both motherboards.
Thanks
