    Dumb question..... Whats the difference between and SO and DIP package?
    Will an SO work in a breadboard?

    When I googled it, it came up with "resembling a flat pack with leads on two
    sides." That seemed pretty DIP sounding to me... Are they SMT?

    As i understand it, "SO" means "Small Outline" and seems to always
    refer to surface mount devices.
    And yes, one can breadboard circuitry with surface mount devices.

    And how might one go about doing that?

  4. Not a traditional breadboard with the 0.1" plug holes.
    To "breadboard" SO chips you'll need an SO-DIP converter board, but
    that is pointless if you can buy the DIP version of the chip.
    You can get ZIF (Zero Insersion Force) sockets for SO chips, but they
    aren't cheap.
    Generally speaking, SO (SMD) chips and components are only for putting
    on PCBs. You can get "general purpose" SMD boards, kind of like
    vero-board, but you have to solder the chip on and then solder
    connections etc - yuck.
    Yes they are surface mount(SMD). Technically they are still DIP (Dual
    in-line package), but they are a surface mount version as opposed to a
    through-hole version which the term DIP generally refers to these

    There are three ways i have done that:
    1) Solder #30 wire onto each IC lead, fan them out, and place onto a
    0.10 grid breadboard.
    2) Flow solder onto a board that has useable trace spacing, then add
    jumpers, etc to other parts as needed.
    3) Flow solder onto my own SMD to DIP adaptor.
