Thank you, Victor
I am gathering that this is not a standard IC device based on your
description but a DIP which has the leads shaped in a gull wing format as opposed
to straight leads as is the norm.
I was under the impression you were using a standard package of which there
are several package types which might be covered by your description
including: the SOP, the SSOP, the TSOP and the TSSOP both of later can be
either TYPE 1 or TYPE 2. (leads on short side vs lead on long side) Lead pitch
will also be important and depending on the device lead pitch can be 0.50mm,
0.55mm, 0.60mm, 0.65mm, 0.80mm, 1.0mm and 1.27mm
From this list you might be able to identify one which most closely
represents your special device and work from there.
Good luck with your project,
Joe

Hello Victor
There is perhaps a bit of confusion in terms here. Dual In-line
Packages
(DIP) are generally through hole leaded devices. The term "gull wing"
indicates a surface mount device which is what seems to be of interest
to you. I
would add to Steve's comments that the component suppliers often
provide
their recommendations as well.
Kind regards,
Joe

Fellow TechNetters:
What is IPC guidelines for a DIP gull wing component lead width ratio
to external copper pad width on lead free
assemblies?
Victor,
