Eagle PCB part design question


#1

I am working on my first Gadgeteer module. I have decided to put all gadgeteer related parts into a separate eagle library. I have parts for each socket label. When I made it in part editor I have used tPlace(21) layer since it is going to be printed. Now, when I put it on a board it stays on layer 21 and there is no way to put it on any other layer.

The question is how to design a part that can be put on any layer?

Thanks,
Valentin

The “part” include the “layers” in it so you can’t make a part that go on a layer


#3

Thanks Gus.

I figure it out. If you “mirror” a part on a board, In my case it is a tPlace label it automatically goes to bPlace.


#4

Yes, some layers are special, like tplace bplace and the copper layers are reversed when you mirror the part to the other side automatically.


#5

Are there any known Eagle issues/tips in terms of text fonts/sizes and actual accuracy of printing on a board?


#6

size 40 or 50 with 12% ratio looks best. Follow what we do on our board.

So what module are you making?


#7

It is a POE Ethernet module.


#8

In what units? Mils?


#9

it is just the number you see on eagle
