Title: Designing Double Sided PCBs in EAgleCAD
Post by: airman00 on March 03, 2009, 09:56:51 AM
I want to design a PCB that is double sided and uses SMDs. Meaning I want to be able to solder on SMD resistors to on the top side but also want to solder on different resistors on the other side - to save space.

How can I make this double sided board in EagleCAD?

In Eagle, in "board view" (where you design the PCB), select the "i" tool (the tool that brings up the "properties" dialog) and click on the resistor you want on the other side of the board, check "mirrored" and that's it!

thanks!  ;D

also quick question about Eagle
I want to rotate a part on the PCB to 30 degrees, but it seems like I can only rotate components in increments of 90 degrees. Know how to rotate the part to a different angle?

At the top of the design page you've got a text box where you can type a command.
Enter this:

Code: [Select]
rotate r30 'IC1'

where "IC1" is the name of your component.

where did you learn all of this? Is there some online resource?

thanks a tremendous amount!

That information came right of Eagle's help file: try the "Help" menu at the top of the application windows.

Hi,

The rotate command can be used in several ways, like "rotate r27" and then click on all the components that you want to rotate 27 degrees. A great relief if many components has to be rotated.

Mirroring the component doesn't change the layer of the component! I wanted to ask whether it should change or not?
All the components initially are on the top layer i.e 1 and common sense tells me that if I want to make a double sided PCB the components to be soldered on the other side should be on the bottom layer. Am I correct in saying so?
