# 4 layer stackup Eagle

Can someone explain to me how I can change the layout order of my 4 layer board in eagle.

I'm sure this is really a silly question, I'm coming from Kicad so I'm a bit green here.

It's not obvious to me how I would do this

Currently its (1+2*15+16)

Layer 1- GND || Layer 2 - Signal 1 || Layer 3 - Signal 2 || Layer 4 - VCC

But what I need is

Layer 1- Signal 1 || Layer 2 - GND || Layer 3 - VCC || Layer 4 - Signal 2

I'm sure its something simple, but not clear how to do it.

Thanks

• If you type drc and go to the Layers tab, you can see the set up for the layers. However you really don't need to identify them as signal/gnd/vcc, etc. The inner layers will be named "Route N" where "N" is the layer number. – Ron Beyer Oct 24 '19 at 14:43
• I'm not familair with Eagle, but with Altium and KiCAD, the program produces a separate Gerber file for each layer. You have to tell the PCB shop in what order you want those files used to create your PCB. I always included a readme.txt file with my PCB orders detailing the layer order, drill sizes and overall board size, and any other special instructions. – Peter Bennett Oct 24 '19 at 16:07

Your layer string is fine for what you need. (1+2*15+16) creates a four-layer board with no blind or buried vias.
