I am a brazilian, could you explain better what you meant in the third note ?

 

Don't bother to upload zip files. We don't risk opening zip files.

 

If upload it with an online virus scan it would be ok ? I had those airwires, i pressed something, they disappeared. The best thing i should do is remake the entire board.

I assume your HT12E is a 18-pin DIP package. Use that foot print which will already have 18 pads of suitable size.

Small pads will break off easily if too much soldering heat is applied. Larger pads are more secure.

Virus or no virus, I do not open zip files.

 

Yes, i thought about the size of the pads, i'll see about that.

 

You had several no connections and near connections in the schematic. I fixed just those. The rest of the ERC warnings had to do with no values.

On your board, you forgot to name the pour ("ratsnest") GND. Use the name command to do that. I did that for you. I also added thermals. You can remove them by using the "I" button and dialog.

It appears you may have changed your grid, either intentionally or unintentionally, while making the schematic. The usual effect of that is wires that are close, but not connected.. So, I snapped all components to a grid of 0.1" and 0.01" (i.e., 100 mil). Then I used the "net" command to remake the connections. The net button is the one on the right:


I would recommend using the "net" button. instead of the wire button in the future.

Here is one simple example of what your PCB should look like with large pads, wide traces and a GND pour:

 

Oh thanks so much john and mrchips and everyone else, i think i got it right now, ground plane done, everything smooth, i'll post the result in a day or two of the receiver board also, thanks a looooooooot

 

I returned with the design i intend to print of the transmitter. Is it correct now ? I increased the size of the pads, and remade the board.

One thing i should ask, i put a 0.1uF capacitor for filtering purposes for each IC, is that correct ? And are they're placed correctly in the circuit ?

Where's the actual design? It looks like you enlarged every pad EXCEPT the ones for the IC, which were the important ones.

 

I made them a little larger, but not that much, i think now is in a good size. Anyway, about the capacitors, is it correct?

 

There may be nothing wrong with your layout but I will show you what I would do differently.
But that will have to wait for maybe another day or so. I can't do it now.

 

Oh, its okay. I'll be making this board in a week or more, so no worries. Any advice would be welcome

 

Please show us the actual design.

 

The schematic and the board

 

I meant the screenshot of the board, like you did before. Take a screenshot of the Eagle PCB and post that, please

 

Oh, but its just like the monochromatic one i posted.

A screenshot of your Eagle screen should not be monochromatic. Do what you did to get the first image you posted in this thread. The monochromatic view doesn't really show the components very well

 

I uploaded two views of the board now in the post above
