I am making my first board with inner supply layers, and when I make the cam
files, the component pads are showin up in the inner layers. Since the
supply layers are inverted, this makes an area around the thru-holes with no
copper, and none of my power or ground connections are being made. How do I
keep the pads from showing up in my supply layers?
Tilmann,
Thank you for your time, I greatly appreciate the help. I have checked the
names of all the layers and nets several times, and I think that they are
correct. I don't know what I'm doing wrong. I have attached a couple of
screen shots to clarify the issue. Help1 is the Eagle layout, and Help2 is
the gerber files open in Gerbv, with only the ground layer, silkscreen, and
drill data shown. You can see that the thermal symbol is shown in the supply
layer in eagle, but when the CAM files are generated, the pad shows up in
the supply layer as negative space. The oval pads on the IC above C10 show
up as well.
Again, I appreciate your help. Thank You,
Paxton
Well I solved the problem. It was fairly easy to fix, although not obvious to me at first. In the CAM Job, pads and vias were selected for each inner layer tab, which is why they were showing up on the inner layers. Duh, right? Deselecting those in the job gave me the following:
Looks good. I now had an inner layer clearance error, which was fixed by activating restring for the thermal isolate under the supply tab in DRC. The final result, below, gives no more errors.
I would like to thank you Tilmann for your help, and I hope that this thread can help others who may run into the same issue.
