Is there any standard for SMD marking?

(1/1)

RoGeorge:
I know nobody has the time to debug to the component level any more, but each time I have to lookup SMD markings it's like shooting in the dark.  I know there are, and even have a few SMD catalogues, but unless the part is a very common jellybean, chances are I'll never find what it is.

I see here "what SMD is this?" question quite often, so what are we missing?  Is there any marking standard?
How is one suppose to know what a SMD component is, and find its datasheet?  How do you identify, for example, non-obvious 3-6pins parts?

No standard.
Google: various iterations of part marking + package name
