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 Jeffrey A. McGlaughlin, C.I.D.

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.
