Soldering to the on-board prototype area question

    I have a board that has an on-board prototyping area (an array of holes).
    I am trying to think of the neatest, most practical way to solder on it. I
    want to put a couple of 16pin sockets (that I can plug buffer into) and 8 or
    16 LEDs comming off them. I don't want a mess of wires eveywhere. It would
    be great if there was a supplier that sold wires with tiny loops connectors
    on each end so I could lay a connector loop over each pin or LED wire and
    solder it in place ( a wire like this: 0===0 ). I tried using small wire and
    making my own loops on each end but it still does not come out well :<

    Any ideas greatly appretiated!

    p.s. I was thinking of buying a simple wire-wrap tool and just
    wire-wrapping -- I like wirewrap for hobby stuff but I thought I saw an
    article that suggested it is not in-vogue anymore -- is that considered OK
    for small stuff like I will have (less than 50 wired connections)?

    Wirewrap has a small coil at each connection,which is not a
    nice thing in a fast cicuit.
    I have used wirewrap wire however to make solder connections
    at the bottom of the board .
    That works very wel, the ww wire is heat resistant, it does
    not crimp while you solder , and the silver coating on the
    wire makes very clean solder contacts,even with part of the
    isolation inside the solder blob.
    Also the wiring can stand quite a little moving around without
    For a one or two unit production ,or development board,
    it works for me.

    Pretty much the same way that you solder to an ordinary PCB. :)
    What I did was get a WSU-30 wire wrap tool:
    and filed off the rivet that holds the little stripper blade that you
    can see in the middle of the tool. I set the rest of it aside, and clamped
    the stripper blade in an X-acto handle. Works a treat, and with a little
    practice, you can daisy-chain them; get a good, substantial tweezer; I
    use this one:

    This is about the worst example I can think of of what you can do with

    It's something I did many, many years ago, and just saw it knocking
    around in my junque box. It'd probably look much better if I'd cleaned
    off the flux!
    If you really want to avoid a rat's-nest of wires, avoid wire wrap like
    the plague. :)

    Have Fun!
