IC Package Drawing Database?

[DaveC]

I've been searching the net for a comprehensive list of drawings of IC
packages, specifically, all things "SO" (ie, SO, SOP, TSOP, SSOP, TVSOP,
etc.). What does come up are lists of packages, but no drawings.

I need to have dimensions listed as well, similar to what is typically
provided in datasheets.

Thanks.

Thats your answer, grab the data sheets. ;-)

Some semiconductor manufacturers also provide package drawings. IIRC
NXP is one of them.

That's what I resort to, although it really would be nice if there was a
one stop shop of package drawings or dimensions. There are so many
different packages now that I can't keep track of them all.

For example this datasheet has 5 different package drawings that it calls
"Small Outline Package", all with different dimensions:

Isn't the idea of a package "name" supposed be a single identity including
dimensions (differing, of course, in length, to accommodate different pin
counts)?

From the same manufacturer, no less...

Thanks,
Dave

According to this source, the same package (listed in the TI datasheet as
"SOP") might a large SOIC-20:

Am I the only one confused?

That's another problem, there are special package types that are called
different things depending on the manufacture.

I've recently worked on some designs around TI chips in their "PowerPAD"
packages which are SOIC and SSOP equivalent but with an exposed metal
pad under the die, and of course different names. I've gone to just
ignoring all the packages included in the PCB software and drawing my
own from the datasheet of each part I use, it's less hassle in the long run.

Thanks for that.

Just my luck: Lattice have updated that document by deleting all SOIC
packages, the ones I apparently need...

A good reference otherwise, tho.

Thanks again.

Board houses usually adhere to the IPC standards, unless its oddball
stuff.

You need the JEDEC standards. Bless their hearts, the standards are free
upon registration.

For example, the "Plastic Shrink Small Outline Package (SSOP) Family.
R-PDSO/SSOP/SOIC" is covered by MO-137E, Mar 2010 over at
http://www.jedec.org/standards-documents/docs/mo-137e

Get thee hence to http://www.jedec.org/

Don't know if its on wwwland but the paper versions of UK RS components
catalogue have an extensive pictorial listing of types with equivalents,
then look up dimensions once the package designation is known.

Yes it can get very confusing. The "Jedec" designations are given at
the bottom of each drawing. AFAIA that designation should identify a
package uniquely.

IC packages are standardized by JEDEC

http://www.jedec.org/standards-documents/technology-focus-areas/registered-outlines-jep95

That's the wonderful thing about standards, there're so many to choose from.
JEDEC stretches that even further everyone gets their own "standards".
