question about soldering the neo2 chip

[hi-tek]

Hi, I have a question. I am kinda new to this modchip soldering thingy. I ordered a neo2 and I know what to do, but I don't know to which point of the pins I have to solder the wires to: the smaller bottom part or the wider upper part of the modchip's pins ? I think it's the wider upper part because the smaller part is too small but I just wanna make sure.

Thanks to anyone who wants to help me
