Wire wrap

[Gregory Toomey]

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.

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.



Use the usual techniques if you wish to reply via email.

Molon Labe!
