iam new for orcad software. I completed designing of 3 layer board successfully and created gerber file also. while i send these gerber file to manufacturer they send me problems like
problem description-1:
the Excellon drill file is missing
problem description-2:
in your gerber data two different bottom layers are given which is not clear to us.
problem description 3:
you uploaded top slikscreen file is unable to load properly


i have used 3 layers named as top, layer2, bottom.

1) You didn't send them a drill file.
2) You defined two layers as bottom layers.
3) There is something wrong with your silkscreen file.

Hi pavan,

PCB must be even number of layer only.don't keep odd layer
while release the gerber.Manufacturer-->artwork-->in pop up menu select the file control and then add layer one by one

Hello , Paven ,

you can design as 4 layers in your soft, and let the pcb manufacturer to delete the unused layer when produce this pcb , then there will be no prolbem in your soft .
