I've been practicing soldering on an old motherboard and i'm just about ready to try the PS2 but I am having trouble soldering to vias. What I do is scrape the via with an exacto knife. Then I tin the wire. Then I insert the wire in the hole and warm the via and the wire together. The thing is that how do I know that I did it right. In a previous post lufcfan posted this website
