So I bought a SEGA CD off ebay and everything was fine until I decided that the duct tape that was holding the battery is was a poor substitute for a battery holder.
So I took my Model 1 apart begun to unsolder the joints that held the battery down. However, one of the parts snapped off and my attempts to empty the hole and remove the remains may have damaged it in the process. Below pictures of the hole that may be damaged. I've tried applying more solder and removing, solder wick, solder sucker, nothing. I will admit I put my iron directly on top of it hoping it would melt the solder inside causing the pin to drop out but that didn't work.
At this point, I'm considering using a small drill or a jewelers filer to clean out the hole however I'm only considering this last option which I will probably put off for a while due to how uncomfortable I am of using them on a PCB. So basically, what are my options? What can I do to save the PCB? Can I simply drill or clear out that hole with a drill/filer and fill it with solder to fix it?
Edit:I'm using a 25W Soldering Iron. Picture was linked in comments.
