I plan on installing the MakeMhz HD+ native digital mod in my 1.6. The only thing I'm concerned with is the AV port which has large solder joints. They remind me of the power jack on my laptop that I tried to replace but was unable to with my soldering iron because the solder had a higher melting point than the 450 celcius my iron is supposedly rated for. Should 450C be good for the entire job?
