Technology and package

autodeskguest

Hello,

 

EAGLE assumes that any part name is composed in the following way:

 

BASE_NAME|TECHNOLOGY|PACKAGE

 

some parts come with another order:

 

BASE_NAME|PACKAGE|TECHNOLOGY

 

 

 

How to handle this?

Thanks

Marco

    IMHO, the "technology" is absolutely senseless/useless anyway. You get

    the same effect just by setting a proper VALUE.

     

    So all my libraries contain devices that are as generic as possible, and

    none of them uses "technology". When putting them into the schematic, I

    assign a meaningful value, and all is done.

    My experience is different than yours. The technology field (since EAGLE

    supports the "append" features for pin/pad) is very useful for me to

    take care of the small differences among parts.

     

    For example the C/I designator for temperature ranges is properly

    handled with the technology fields, allowing you to have ONE part in the

    library. Or think about an LDO or TVS family: they could have dozen of

    different voltages. Each one with its own order code.

     

    If you don't use the technology fields you must create a different part

    for every variant!

     

    The best would be to define the "part name" according to the

    manufacturer specifications. But I admit this could be quite complex to

    implement.
