/diy/ - Do It Yourself

I am trying to solder an extremely small 40 pin connector onto a board
if I have the iron on it for more than even a second the plastic will get melty and the pins will fall out

How can I do without $5000 in tools?
My idea when I get another connector is to try and tin or dip each pin then solder the tabs to the board to hold it in place then attempt to barely touch each pin just enough to melt the existing solder to the pad

pic semi related, about the size of the pins
