Thin pad width EXCEPT on inner layers... What's up with this ?

have you checked your DRC restring settings? did you make the outer

this would cause the outer layer pads to "disappear" but be visible when

inner layer (with normal pads) is displayed.

Ahhhh.....   That was it !

I don't know how that got set to 1 or whatever small amount it was.

Other PCBs are just fine. Might have had something to do with me

changing the eaglerc.def file or something like that.

I haven't thought about restring in many years now.

Much better now !

Thank you VERY much, Gary !

Great question, Paul... Yes, it is displayed.   Let me try to post a

picture of the area in question with inner layers (layer 8 and 9) on and

off.

InnerLayersOff.jpg has all the important layers on except for my 2

middle layers, 8 and 9.  Top and bottom (1,16)  pads, vias, etc. are

all on.

InnerLayersOn.jpg is actually the same thing as InnerLayersOff, except

for one of the inner layers are on (8 or 9). Doesn't matter which inner

layer is turned on.  Also, J3 (RJ11 jack) on the right is right out of

the conn-amp library.

I can't seem to add the pictures to this message so here is a link to

them....

Maybe this is NOT the problem ??   The pads that are not showing up on

top and bottom layers while inside layers are off are ALL of the pads.

Not just the power supply pads.

 

Might be something else ??

Yes, that is probably it...  However, when routing on the top and

bottom  layers, it is hard to see the REAL widths of the donuts that

I have to avoid.  I believe that the full donut width should be shown

on top and bottom layers, even while inside layers are off.

What is the reason that a part would have ultra thin pad width

except when inner layers (4 layer PCB) are displayed ?? Yes, some

of the pads are GND etc where the inner layer IS gnd.

 

If I cut and paste the part into an empty PCB file, the pads appear

full width when the PAD layer is turned on all by itself.

 

I _think that this outputs OK and I have seen this before, but it

makes

routing difficult unless those inner layers are turned on and

displayed.

Sometimes I do NOT want the inner layer ground plane turned on

while routing outside layer traces.

 

Where do the pads go ?  Aren't pads supposed to be on the top and

bottom layers PLUS the inner layers ?

Do you have pad layer displayed? Pads and via's are not drawn on the top

and bottom copper layer.
