Well back in the days when i could see, I used to build stuff and used
solder, but increasingly even then automation for mass produced products
meant that surface mount and wire wrap techniques abounded. I'd imagine with
the banning of leaded solder its more likely that machines can make better
joints than humans even if they could use soldering stations easily.
Back then the only folk still soldering in industry were the development
types. If a pcb failed in test, then it was taken out junked and replaced.
Gone are the days when simple hands on component substitution was cost
effective it seems.
As for led lamps, I imagine they are still in the early stages of
evaluation. Nobody has had them in service long enough to refine colour temp
and reliability methods. It will probably only get better though as the
efficiency is so much better than alternatives, they are going to make it
work.

There is a shop in town that is all LED strip lighting. So far no failures
noticed, but I will estimate the total number of LEDs and monitor over
time. I would guess , sitting here, something like 20,000 5mm LEDs in
total (not the higher powered types). I feel like running a red/orange
felt-tip along all
the cover-strips of the LED runs, as its that horrible stark blue-white.
Doesn't take much pen ink to give a much warmer tone (to CFL bulbs anyway)

This article has soldering as a dying art along with trug making etc

http://www.theguardian.com/culture/2...heritage-craft

perhaps they meant soldering as in tin-smithing.
But on the other hand how much hands-on soldering rework of modern day
mass electronics production is there?
