"I remember something called 'Nylese' from many years ago. It too was stripped by the heat of the iron. Burning plastic fumes - now that's GOT to be unhealthy!" post #19


I once wired up 66 TTL's with wire wrap wire, but I chose to strip & solder each connection, so there was no burning. Firstly I ran the power rails down the long axis under each IC and fitted the bypass caps.

There are over 900 connections and I realized it would be a major issue to keep them orderly. I used as many direct surface links as possible with bare wire. I also routed the wires in bundles down the long axis of the IC's and laced them up with surgical silk thread, you can just see it in the photo. The method allowed for continued access to the IC pins for easy soldering. If its a rats nest instead, it becomes difficult to get at the pins.
