Electronics-Themed Comics

I was hoping that since these electronics-themed comics appeared in December and January (1967 and 1968, respectively) issues of Radio-Electronics magazine, they would have Christmas and/or New Year subjects, but unfortunately that is not the case (these are being posted on the RF Cafe website on Christmas Eve). Anyone who was around during the vacuum tube circuits days will still relate to the page 92 and page 26 comics. Lots of opportunities existed for open or intermittent contacts with all the connectors, tube sockets, and cold solder joints on terminals where point-to-point wiring was done. While a lot of those issues went away with solid state and integrated circuitry and printed circuit boards, the remaining weak link is connectors. My troubleshooting experience since the disappearance of vacuum tubes has been that the majority of failures are the result of dirty connector pins and sockets. I bet that reliability calculations for typical systems - from home appliances to automobiles - are heavily burdened by connectorized connections. Soldering, crimping, or welding interconnects that are not usually required other than to facilitate assembly or replacement would greatly improve product reliability and lifetime.

"It's a vibrator ... I got tired of kicking it."
"To save
you tie, I've already shook, kicked and jiggled it."
"No wonder the picture is confusing ... you didn't turn on
the sound and you forgot to turn your radio off." |
