Prepare all the Boards that are to be Combined
Make sure that the designs are individually complete as you would want them to be manufactured. To start, open each PCB design that you want to combine, one at a time. The schematic may open up but note that we will not be dealing with the schematic since the initial design was already completed. Go to the Eagle PCBs layer setting section and select all layers for that PCB. Select the whole PCB layout and group the whole board design. Now you should be able to copy the PCB design. Some older versions will not do well with the copying option. In this case, CUT the design instead of copying.

Position the PCBs the Way You Want
From here, make a new PCB board le and paste the copied or the cut le by clicking on the paste icon. Now you can position the PCBs the way you want. You can also make changes, but you should avoid any major changes since the board is already complete and ready for manufacture. Also, making PCB components or trace changes will result in errors since they have no associated schematics. If you feel that you should make major changes to the PCB, you should make the original PCB design changes. Then, when all is well complete, you can proceed to PCB combining steps.
Add the boards you want
Using the same process, you can add as many boards as you want. As you combine the boards, you need to keep in mind the manufacturer’s capability and capacity. Following your manufacturer’s PCB rules will ensure that your board will be manufactured lawlessly. After you are satisfied with the board’s number on the board, you can comfortably generate the required files as usual, as if it were a single board.
