Flipping a Component, but keep it on Top Layer

bazz

I flipped a component on my board because it seems the only way to get to the desired orientation. Now, the place silkscreen is on the bottom of the board. I want the place details to stay on the top of the board.

    Eagle won't do that, because it shouldn't. The pins down the left side

    of a component are down the left side of the component and no amount of

    wishing will change that. If you flip the component you are going to

    have to fit it on the bottom, otherwise the legs are waving in the air.

     

    What you're actually saying, behind the details, is that you've wired up

    the component wrongly. In this case, as you say it's a 2x20 pin header,

    you may have the option to move the signals you have on odd pins to the

    even pins and vice-versa. That would be the right way to do what you want.

     

    Alternatively, although this is a kludge, you could define a mirror

    version of the package and add it as an option on the library component.

    I do slightly sympathize with this option because the socket housings

    often have a pin 1 marker on what the IDC ones call pin 2, so you can

    blame that for the confusion!
