[edit] narrower comment

i'm 99% sure the 28 pin soic that microchip supply pics in is actually wider than the 28 pin skinny dip they supply the same chips in. Is this standard or a peculiarity of pics? Plugwash 09:41, 2 April 2006 (UTC)

Sadly, I am familiar with this. It seems SOIC for most manufacturers only defines pin thickness and pitch. So on one of my boards, our footprint was too wide on one SOIC, and too narrow on another. Luckily it was a low speed signal, so our QA folks were kind enough to rig it to work since it was only a prototype... — RevRagnarok Talk Contrib 20:16, 4 December 2006 (UTC)

[edit] Authoritative source

Where is an authoritative source for information about electronics package outlines, form factors, etc.? JEDEC would be one. Are there others? I know that certain package types have several names, probably depending on manufacturer. The subject is much more complicated today than 20 years ago. There are so many package families, and each has so many variants. --HelgeStenstrom 09:23, 18 August 2006 (UTC)

[edit] EDA Symbols

Is there any way to post package footprints for EDA software here? It would be great to have all Wikipedia pages on chip packages have footprints for Orcad/Protel/Eagle etc.

I don't think that would really meet the objectives of WP; it's not supposed to be a symbol library repository. :) And I know I have been stuck drawing enough OrCAD symbols to tell you that they're just too individualized. — RevRagnarok Talk Contrib 20:18, 4 December 2006 (UTC)

[edit] Technology

Is SOIC a SMT? --Abdull 18:57, 21 November 2006 (UTC)

Yes. The gull wing in the illustration does not go through the PCB. — RevRagnarok Talk Contrib 20:12, 4 December 2006 (UTC)

[edit] NSOIC

What is the NSOIC package? -Marcus
