I want to solder the copper shims you see in pic related to the aluminium contact plate.
There are two problems here. The first, heat is transported really fast to the heat pipe, so how do I get the solder(paste) and the metals hot enough without the heat pipe exploding or bulging on me? I have a 550°C heat gun. I know that I have to grind the aluminium first to remove the oxidised coating.
The next possible problem is corrosion. As far as I found out aluminium, tin and copper are pretty passive and the corrosion should be really slow as long as it isn't exposed to current or excess moisture.

Is this sound? Anyone know how to best proceed here?
