How many of you have come across "multiwire" boards? ... basically a pcb substrate where thin magnet wire was routed by a nc machine and coated in epoxy,

Used on a defence airborne radar project about when I was a fresh graduate...

Further recollection:

I seem to remember seeing a sample that had been cut in half, so that you could see the little wires...


I did a multiwire board, too. At my first day job after college, I worked for a defense contractor in NJ. The bureaucracy of the place was such that if we wanted to do a proper PCB we had to go through the drafting department and they were too busy for my little job. I wonder how companies like that can remain in business. Oh, wait, I don't wonder at all.

I'm sure I saw the same sample, too ;)

                  I remember these            01/01/70 00:00      
                     I agree            01/01/70 00:00      
                        there were several influences            01/01/70 00:00      
                  but this looks like - OK let's call it DIP...            01/01/70 00:00      
                     Density            01/01/70 00:00      
                        this is beyond my imagination            01/01/70 00:00

   yes            01/01/70 00:00      
   Some serious wire-wrapping for you...            01/01/70 00:00      
      thanks            01/01/70 00:00      
      I see the wires, but where's the wrapping?            01/01/70 00:00      
         WHAT??? You want details?            01/01/70 00:00
