Take a look at this:
https://nepp.nasa.gov/docuploads/06AA01B...8739.3.pdf
Though oriented towards PC/surface mount there are termination drawings applicable to terminals that could be point to point...
Note the "strain relief" bending techniques for components...
The 60/40 has a longer "plastic" state meaning that it takes somewhat more heat to melt and stays "chewy" longer than 63/37.
When repairing an old joint the eutectic alloy 63/37 is a better choice as it will amalgamated with the old joint and lower its melt point, further than 60/40 meaning flow new 63/37 on old joint then suck out all. When ever any solder alloy is used in a joint it alloys with the base metals and raises the melt point. Fine for new work but when returning to the same joint it will need a higher temp to flow or apply the eutectic solder first..
The notes are in text as to "clean as you go" using rosin solvents.
May also consider either a magnifying visor or a few power lighted glass on a crane for the work bench.
Bench also needs LOTS of lighting to see the details and the wire "hairs" that often happen with stranded wire.. Stronger lighting makes the iris in the eye close more, we will get a greater depth of field so objects over a range in depth will be in focus. Makes "Boo boos", much more noticeable... The new LED lights are great as have adjustable color and brightness without the heat. I had all quartz lamps on my eLab bench at work 30 ya, roasting!...
