# Warnings during real-PCB transfer

Typical warnings while transferring a circuit to real-PCB:

- Some connections could not be routed. To improve the chances that real-PCB can route the circuit, try one or more of the following settings:
  - pre-place fewer components
  - use a double-sided board
  - use thin tracks
  - allow real-PCB to resize the board
- There isn't enough room on the board to place all of your components. This will occur only when using the custom transfer option, without allowing board resizing.
