I tend to work hot.... so i can work fast.

I assemble new MPU boards at 750f so I can whizz down a line of solder joints spending less than 1 second with my iron on each point. At 650, it would take much longer.

Bally rectifiers I am assembling with 2oz copper, majorly wide traces, bridge rectifiers with fat lugs and metal cases... 850f and a big chisel tip still takes some time to heat up those joints.

Kester 331 is my new fav solder. Specially on new PCBs. Water solubile flux clean up!

Its all about how much solder you use with this technique. Solder only wants to stick the pads and resists solder mask or the PCB material. If you bridge two pins, just clean off your (chisel!) tip and use it to wick off the excess solder bridging two pads.
