SOIC-28 and SMT

autodeskguest
autodeskguest over 16 years ago

Hi there,

 

At the company where I work we have been using Eagle for some time. But

recently, we are making the migration to SMT designs, and I am concerned

that the support for SMT libraries in Eagle seems poor. For example, I need

some straight forward 28pin SOIC packages, but when I look in the IC

packages library there are only PTH components. I checked in the on-line

download library but again nothing.

 

My conclusion is that Eagle is a really great PTH package, but for SMT I

will need to look elsewhere for a new layout program. Is my observation

accurate, am I being unfair, or have I looked for SOIC-28 packages in the

wrong place?

 

Cheers,

Ralph.

    Look in ref-packages.lbr. There is a wide variety of SMT packages there.

    Hi Ralph,

    I think you checked in the wrong place.. at least from my opinion and

    experience Eagle is good in both PTH and SMT packages!

     

    For your soic28, check the library "ref-packages.lbr" between the

    default libs. And another tip (working for me): if you use "ADD" button

    in the layout editor and you search for a package (ex. SO, SOIC) , it

    shows you the libs where that package is in!

     

    hope this helps,

     

    N.

    Don't conclude so fast image

     

    For example, there is  SO28W package in the 74xx-us.lbr, that's where

    the typical logic chips are found. But as usual always check packages

    thoroughly against a real footprint and the datasheet.

    I have been able to find all of the basic SOIC, SOT packages just

    fine... you will have to make your own library parts at times, but it is

    not too time consuming, and obviously quicker then learning a new software.

    Yep. Yesterday I needed a SO24W. Took me about two minutes and I found

    it in some other library. Can't complain at all. Actually I found two,

    and one must carefully compare the footprint etc. to the datasheet.

    Don't blindly trust library parts just because they came with the CD, as

    far as I know many are contributed by third parties (users).

    You may also want to take a look at smd-ipc.lbr, which has a good

    selection of SMD footprints.

    And try ref-packages.lbr.

    It contains all packages that are used in the EAGLE libraries.
