I fix the two pins on a side of circuit with small soldering iron. When I was sure, that circuit is on the right place, that I applied flux on all pins which helps with better diffusion of tin and I soldered first all pins on one side and next on the opposite side. A lot of pins was soldered together. Overflowing tin I easily drain with solder wick.

Next I soldered wire junctions and all components from the upper side and last connectors. PCB is designed with only one side and two wire junctions.
