Which model PSX are you installing the chip to?

Although essentially the same, some are easier than others. The main boards are all double sided and have a prolific anount of SMD divices some of which you are required to solder to, other soldering points constitute a small pad on the board.

Always "tin" the respective solder points and the ends of the wires before actually soldering the wire to the joint, by "tin" or "tinning" i mean add a small amount of solder to the solder point and wire before actually making the joint. This process reduces the time the soldering iron is in contact with the board and also reduces the chance of a dry joint.

Hope this helps.
