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,
