Add holes for through hole components

But for the pads without connections, use plain vias.

They are inserted/placed in the board only.

You can still connect this vias with the connect command (in the board

editor - to form a GND rail for instance)

 

Are you sure? I thought the connect command was used in the library editor

to connect pads to pins in a part?

you are right, it's the 'signal' command you use to create connections

(airwires not tracks) in the board editor, but ...

the 'signal' command only works with parts, not on vias.

For vias you either need to use the 'name' command or give the 'via'

command the signal name:

     via 'signal-name'

sorry for the confusion (no more posting before coffee in the morning)

Firstly to create a components in a new library by:

a. defining a package (which just consists of the pads of the size you want),

b. defining a symbol to associate with the package,

c. creating a device that correlates the pads of the package with the schematic symbol.

From that create a Project and within that project create a schematic file.

Place your newly defined device onto your schematic (for a proto board with no connections you won't have to define any nets),

(I.e. Your schematic will just be a bunch of non-interconnected components)

Then click the SCH/PCB button and allow EAGLE to create a PCB for you.

Now you can move the device into the position you want on the PCB.

The Schematic and PCB are closely linked allowing you to switch back to the schematic to make changes and by clicking the SCH/PCB button it'll place any new components on the PCB file.

Mechanical holes don't necessarily need to be included on the Schematic and can be placed directly on the PCB.

Ok, so if I have understood well, you suggest me to start with a schematic creating the component "board" and then go into the board page in Eagle.

I will try to do this. Thank you very much.

If you look very closely you'll also see the two pads with the enlarged holes as per your photo.

It also makes for a good familiarisation practice session with EAGLE for Library, Schematic and PCB editing.

It is always best to schematic capture a PCB because it allows revisions and additions to it to be easily accomplished.

For example - your Proto board - There will most likely be a stage where you want to add power rails or planes to it.

Facilitating this is done easily using a schematic.

There's no reason why you can't capture the prototyping area as components and have them placed on your PCB.

If fact EAGLE works best in this mode because it switches between its schematic and PCB for its Design Rule Checking.

I just kluged this up in moments to illustrate the point. Complete with mounting holes.

The size of this board is at the maximum freeware limit.

Hi,

ok,,, in this way you can create your board as a component in the library.

Because if you place the pads in the schematic then you can have a lot of work to sorting that on the pcb.

But as a component you'll place it all directly on your defined place and they will stay it on there.

Then you can draw the logo in the symbol of this pcb.

Just make a defined number of pads and place it as group where ever you like.

There are many ways to do it. The one in this photo was created by making a component for the pads. To simplify further I created a component that was a block of pads (e.g. 4x4 or whatever).

Thank you all.

I am not importing nothing from the schematic page because I don't have other components on the board, just holes and a brand logo, so I am making directly the board in the board page of Eagle.

For a bettere understanding, I am making this simple type of board (see figure below) but with a custom size and a logo.

If the pads are going to be isolated for a prototyping board, try placing test points with the desired pads on your schematic and then placing them on your PCB.

If needed make your own test point component.
