How to solder flight controller and/or PDB

[Craos]

I am building my first quad. I am doing something terribly wrong, but I just don't know what ... I have already destroyed 3 flight controllers and 1 PDB when soldering it. I setup my soldering station to 300°C ( 572°F ). I tried even lower - about 280°C, but it doesn't work especially for big engine and battery wires. I place solder on the board, I place it on wire as well pre-heating it and I quickly attach it to the board. Sooner or later board stops working .... Please, can anybody advice, what I am doing wrong? Should I use any special cooling?

Make sure you are using regular 60/40 rosin core solder and have properly tinned the tip. I also always use a touch of Kester RMA flux.

Thanks, that's exactly what I do ... I went through the link you posted - the guy goes the opposite way - he increases temperature to 370°c, so he can work quickly. Probably that's the issue as I am trying to lower my temperature as much as possible.
