    I'm looking to mount a chip that comes in an 8-pin LCC package (5 mm x
    5 mm x 2 mm ceramic). However, I've yet to be able to find a socket or
    adapter (under $50) to accept an 8-pin LCC chip. Is there any
    suppliers for 8-pin LCC sockets or adapters that I'm not aware
    of/haven't found yet? I'd prefer to convert it to a DIP type socket,
    but am open to whatever I can find...

    For reference, the part I'm looking to mount is located here:

    Thanks in advance,
  2. The units you are looking at, are adapters designed for applications like
    programmers, inserting test heads etc., hence the pricing. Generally
    unless a part needs to be removed for programming, a surface mount part
    would just be soldered in place. The cheapest solution if you just need to
    remove the IC assembly, or want to only have DIL layouts on the main
    board, would just be to use an interposer board, with the IC layout in the
    centre, and two pad rows for DIL headers at the edges.
    If however the chip really needs to be socketted for some reason, then the
    pricing will depend massively on the quantity involved. For mass
    production, a system like:
    Will give the shortest interconnection, and in bulk, a good price.
    I don't know if it is one of the ones you have found, but Loranger part
    no: 03450 081 6215, might be the required socket, and should be available
    a lot cheaper than the sort of pricing you are mentioning.

    Best Wishes
  3. For one-of, glue this chip upside down onto a dip8 socket,
    then use tiny wires to connect to the pins.

    Fantastic. I believe that Loranger socket may be what I'm looking for.
    I'm inquiring about the contact locations to make sure the contacts
    will match up. Hopefully they accomodate small orders.

    Regarding interposer boards, are most custom made? Or are there any
    commercially available boards that would fit this chip? I'm basically
    looking for any way to mount and connect this chip. (I'm a mechanical
    engineer by degree, which might explain the basic questions)

    Thanks again for the help,
  5. There are commercial interposer boards, but generally, unless you need
    thousands off, it is cheaper to just make a custom board. Remember that
    there are prototyping PCB board companies who price only by area, so you
    can just do an artwork for a dozen such boards, and the cost will probably
    only be a couple of dollars each.

    Best Wishes
  6. does a number of breakout boards for analog accelerometers
    - I'd reccomend looking there.
