Ioan -

The JEDEC standard you are looking for is Standard 95. This should be in the
free download section of the JEDEC.org web site. A word of caution, this
standard addresses *most* of the standard packages but recently I have found
that IC manufactures have started creating *new and improved* packages that
are not registered with JEDEC. The best (or worst)example of this I have
come across lately are the SOP8-SSOP8-MSOP8 and the DPAK-D2PAK-TO253AA
packages.

Good Luck

Subject: [TN] Component packages


Hi Technos,

anybody aware of the existance of a standard on component packages? Like
something that shows a little drawing of the component and says this is a
SOIC8, this is a QSOP and so on. You know, things get really complicated
when it comes to crystals and odd forms.

I feel the need of this kind of standardization since in the contract
manufacturing world we meet all kind of denominations for the same package.
Each client seem to call the same component in a different manner.

I checked the JEDEC site, but there are so many standards there... Maybe
your experience could give me a more precise hint.

Thanks very much,
Ioan
