I have a complete board which is sent to factory. However, for pricing reasons it would be better to mirror the whole board. This means that everything that was on the top, will be on the bottom, and vice-versa.

How can I do this in Eagle? The components and wires should remain as-is. But everything goes onto the other side.

Could you recommend something to do this?

    \$\begingroup\$ How about you rename the layer names and export the gerber?. If the connections are as-is i don't understand how it is going to affect the manufacturing costs? \$\endgroup\$ – ammar.cma Sep 14 '16 at 9:20
  • \$\begingroup\$ I think it is better not tricking with the layer names. After a few months or years I'd bet you won't remember which layer is renamed to what. Regarding the cost: it's because the silk screen. This mirrored one has the silk on its bottom. But none of the others have bottom silk. So in this case I need to order a layer for the bottom silk too which is avoidable by mirroring the whole board. \$\endgroup\$ – Daniel Sep 15 '16 at 6:29

Go to the layout window in Eagle, activate the Group Tool, mark the whole board. The next step is to select the Mirror Tool, hold down CTRL and click once on the board. That's it.

  • \$\begingroup\$ Thanks. This means that all and everything (wires and components) that were on the tPlace will be on the bPlace afterwards? \$\endgroup\$ – Daniel Sep 15 '16 at 9:53
  • \$\begingroup\$ Yes, basically the layers with t... prefix change to b... prefix and vice versa. \$\endgroup\$ – auoa Nov 28 '16 at 16:17
