Images of various packages and their names from Sparkfun.com

Hard Way HughesThe names of various packages can be found all over the web, but I was unable to find a single comprehensive source (not covered by copyright) in two hours of searching -- let me know if you find one that we can share in the course.  You do not need to sit down and study these patterns and names -- you will pick them up naturally over time as you gain familiarity with the assembly space.

Here are a few additional resources to get you started.  The list is far from comprehensive.

Vendors

Texas Instruments

Their page http://www.ti.com/support-packaging/packaging-tools/find-packages.html sorts their parts based on the package type.

BGACSPQFNSO

And their document http://www.ti.com/lit/sl/sszb138a/sszb138a.pdf lets you find the relationship between a package name you are familiar with (e.g. BGA, QFN, SOP) and their proprietary part naming / numbering scheme.  

NXP

https://www.nxp.com/packages provides a search page that will locate a datasheet specifically for each package they manufacture.

Analog / Linear

Provides engineering drawings for each package at https://www.analog.com/en/design-center/packaging-quality-symbols-footprints/package-index.html.
