For what it is worth, the company I worked for prohibited the use of
soldered connectors for terminating bonding or power wiring. Especially
with regard to bonding, dissipating any lightning strike energy through
a soldered connector could cause it to enough to melt the solder. In
doing some microwave site upgrades I did pull out a previous generation
of bonding wiring that was soldered and some connectors had signs of
being heated since installation.
In my shack I use crimp connectors and a quality crimping tool with no
problems.
