I worked at a Marconi semiconductor plant in the 80s. We used wire wrapping on loads of prototype boards. Good to see this old tech resurrected!

This brings a lot of memories back. I wired-wrapped thousands of DSX panels. Although I had the electric gun. Wire wrap and lacing.

Thank you for demonstrating. It is always good to have more techniques at one's disposal. This would seem to be a good way to connect remote indicator LEDs where soldering is tedious and there is usually a fair bit of plastic in close proximity.

I have been a electronics hobbyist for 30+ years...I was only vaguely aware this technique existed. I am surprised not to see it more with circuit diy'ers. My bet is, the discovery of the technique hasnt been made. Very cool share. A very old, but very useful potential method.

I also learned that the pressure of the wire against the post is enough to surface weld itself together over time. So thats something :)

It is easier to make a printed circuit board using photoresist and a photomask. It takes me about 20 minutes from start to finished double-sided printed circuit board (without drilling).

The cost of the wire-wrap sockets is part of the problem. And any goof is usually a painful thing to fix. That said, I have everything but motivation to do my own WW boards. :)

Good when the signal speeds were not too high. Lots of Inductance and stray capacitances. Remember this from the Eighties at work. Never used it for hobby, making a pcb was easier. Wire rap worked by forming a cold weld on each corner of the pin. Very reliable connection.

Capacitance should be lower than with a PCB? (Or at least a ground plane one, which I always use for such as this). I've used it with 160MHz digital circuits without problems. From Wikipedia: "Wire wrap was used for assembly of high frequency prototypes and small production runs, including gigahertz microwave circuits and supercomputers. It is unique among automated prototyping techniques in that wire lengths can be exactly controlled, and twisted pairs or magnetically shielded twisted quads can be routed together."

I'm a big fan off Wire Wrap, I've built many complex boards with it and it was a great way to builds prototypes with DIL devices, but now, with the cost of PCB's being so cheap and with surface mount being so common, its just easier to build a PCB. I now find that I'm using old wire-wrap wire for bodge wires on prototype PCB's.

Nice video, can you make a video showing the full process from the ground up? I see sockets are solded at some pins, I suppose it's for fixing the socket structurally
@RJTC
Жыл бұрын
I usually solder the corner pins just for fixing - though they are often power & ground as well. Also, I solder any pins that will have direct component connections, as it's simpler to do that than have link wires, where it is avoidable. I'll see what I can do for a full construction video, at some point?

@@RJTC I never used wire wrapping construction technique so I would like to see the full process, from planing the chips distribution and "backplanes" or buses to making traces (are all made of wires or some are made with solder or even with air soldering?) and also if components must be prepared in any way . Thank you very much for your videos.

Can we use wire that falls between 30 and 26 AWG?
@RJTC
2 жыл бұрын
You could, if you got a wrapping tool or bit intended for that gauge, and it was not so thick that it distorted or twisted the pin rather than wrap properly. The original full-size wire wrap system used 26WG if I remember right, but with rather larger connecting pins; the newer "miniwrap" standard as most parts are now for, is intended to be used with 30AWG wire.

It un-wraps as easily as it wraps, leaving the pins ready for re-use. You only need new wire! I generally just solder the corner pins to hold the sockets in place, unless they need conventional components connected to them as well.
