I am soldering a Mars II MA-303 modchip into my ps2 (v4 SCPH-35001). I finished soldering all the points except points A,B,C,D,E,F,G,H,I. These points are to be soldered to the back of the motherboard onto very small points. I a wondering if anyone has any tips on how to solder these points. They are about as big as the period at the end of this sentence. They are like little holes, but they do not pierce the board.
