Interesting wiring guide find, thanks NASA!

I found this in a wikipedia source link, thought it might be of some use for us electronics hobbyists (and professionals!). Good for newbies too that want to avoid crackly connections or other issues. If it works for rockets, it's probably good enough for me!

Enjoy!

Interesting link, I see they remove the gold plating from gold plated component leads before soldering into a PCB, must be to improve the reliability of the solder joint.

Here's how it was explained to me:

the gold on the pins should be scraped off (!) and then the pins be tinned with solder, prior to soldering to the PCB. This is pretty important, otherwise embrittlement will occur over time (ie crappy socket connection - the opposite of what you want!).
The gold will give you the corrosion free sockets you want, as Dave says, but if you don't prep them right, you'll get a <worse> connection than the plain sockets. :evil:

To clarify myself, where the gold meets the tube pins, is very good. But where the socket meets the PCB, it must be scaped & tinned as stated above.

Sweet!

Adding it to the collection

Well, remember when they lost that space probe a couple years ago because someone mixed up metric and standard?

Metric is standard, you are the ones who are lagging.

Excellent resource! Worth having a broad variety of termination options in your toolkit. I've also found NASA videos on topics like soldering to be a good resource.

Thanks,

I worked with a guy who was a NASA certified solderer. I watched him replace a processor chip that had maybe 50 to 100 legs. After he was done you could not see any signs of the chip replacement.

You should watch this guy solder. He makes it look easy. That 603 is about as big as a gnat's turd.
