Before there were Dinosaurs, there was Wire Wrap (Old Dog, New Trick #001)

[mhoulroyd]

I feel my age when bringing up the names DataCon and Mupac, back in the 80s and 90s they were the leaders in wire-wrap technology. At that time, I worked for a little no-name company that tried to compete (mostly miserably LOL, but we tried). Some of the wire-wrap applications especially in telecommunications saw giant surfboard size PCBs, assembled with thousands of wire wrap pins, like a bed of nails, wrapped with various colors of 30AWG Kynar wire. Wire-wrap was ideal for making reparable electrical connections without requiring PCB traces.
I want to say that wire-wrap prototyping went prehistoric once microprocessors achieved 25mhz speeds. Like any proven technology, it will find applications forever in time.

Out of the "Old Dog learns New Tricks handbook" I would like to present a possible approach to stacking multiple PCBs using 3-Level Wirewrap pins passing through top and middle PCBs to plug into a receptacle socket, which can accept .025" square posts. So if you ever considered how to create pluggable modules with traditional screw machine technology, this may present a concept to you. If you would like specifics on the parts required, email me.
