  1. I dont see this being used much. Has it gone out of fashion, or is there
    something better?

    A cheap manual tool would seem ideal for prototyping.

  2. Gregory,

    I used wire wrap for a lot of prototyping. The tools and materials were
    never really cheap, especially the professional ones. Over the years the
    prices tend to rise rather then to fall. In the same time design tools
    became common and so the time required for designing a PCB became much less
    then the time to wire wrap a proto. Moreover redesign or adapting an
    existing one became much cheaper this way. So wire wrap almost extincts.

    For private use I had - and still have - a hand tool from Radio Shack. The
    had relatively cheap wire and sockets. Had, because Radio Shack disappeared
    from my country. Tools and materials are still available from professional
    suppliers (Farnell p.e.) but expensive. So even for private use I tend to
    design a PCB proto rather then wire wrapping one.

    Wire wrapping is still used and is OK for low frequency non critical
    layouts. With high frequency circuits, there is too much capacitance
    and inductance. Breadboards are the worst. "Dead bug' is good for high
    frequency circuits.

    If you want an excellent reference on prototyping, see the Linear
    Technologies Application Note 47 by Jim Williams, it's one of the best
    app notes I've seen.

    Sometimes it is quicker, sometimes not. Just depends on what you have
    in your junk box. The biggest problem is stripping the wire w/o
    breaking it for the 2nd connection point. I use it more than
    protoboarding, easier than solder for me, I can physically check the
    connection's quality and conductivity, and I don't have to worry about
    solder bridges on close and narrow traces.
