I repaired and calibrated flight computers for the Bendix Corp for six
years.When I started they made everyone
attend a five day soldering school .We used solder that
was about 1/32 diameter that consisted of 95% silver and
5% tin or antimony, Most of the wire was 22 GA.silver plated copper.The
insulation was Teflon.On a post terminal
they required the wire to be wrapped 5 times and when it
was soldered you had to be able to see all of the wraps.
The solder was rosin core and you used a 17watt iron.
These computers flew in F-105's and just about every type
of commercial airliner all around the world.We washed all
solder joints with Acetone,I consider this to be ultimate
quality.
