When connecting a bunch of components in something that will be subject to repeated heating and cooling, are soldered joints likely to be more or less robust than wire wrap?

Intuitively, it feels like wire wrap should be more resilient, but I'm not certain of that conclusion, and a poster here suggests otherwise: https://www.diyaudio.com/forums/tubes-valves/287205-vacuum-tubes-wire-wrap.html

However, after much experimentation, it became clear that wire wrap was only good for the short term, by itself. If the piece of built-stuff flexed much, then eventually oxidation would set in and make some one of the hidden dozens-to-hundreds of connections vexingly noisy. And never when debugging.

Is that correct, or is wire wrap likely to be more robust if done better? Or are there other factors to consider?

    \$\begingroup\$ I have always read that wire wrap is extremely reliable if it is done correctly. The wire wrap excludes oxygen so there should not be oxidation at the interface. But even though I am defending wire wrap, I would much rather put my trust in a soldered PCBA, just for ease of assembly. These are just opinions. \$\endgroup\$ – mkeith Apr 14 at 8:18

    \$\begingroup\$ For repeated cooling/heating, you need to consider humidity which in turn causes oxidation. For such environments soldering is preferred. And also some manner of PCB coating. \$\endgroup\$ – Lundin Apr 14 at 10:13

    \$\begingroup\$ When done properly, the wire wrap wire will be deformed by the sharp corner of the square post creating a gas-tight seal. I have 40 year-old wire wrap boards that still work. Both are reliable, reliability should not be the primary reason for your choice. \$\endgroup\$ – Mattman944 Apr 14 at 11:06

    \$\begingroup\$ @rwallace What happens when you cool hot air, or when you take a cold object and move it to a warmer location? You get moisture, which is the death of all electronics and is generally unkind to most metal surfaces as well. This is why gold plating is used for connectors, because gold is much less sensitive to oxidation much better than tin or copper etc. For high-reliably PCBs you even use gold-plated pads. \$\endgroup\$ – Lundin Apr 14 at 11:14

    \$\begingroup\$ Space flight uses welded joints in preference to either when it can. A well-done wirewrap joint should exclude gases from the interface and so prevent corrosion, just as a well-made solder joint should last for a long time. Solder has so many other advantages over wrap that you'd have to have good evidence of solder's unreliability for your particular application and temperature range to pick anything else. \$\endgroup\$ – Neil_UK Apr 14 at 11:55
