Repairing faulty connections
I’m not sure about fiberglass pens, but I’m open to other options. For your project, you could try using the low-temperature solder paste and smoothing it over the traces with a bit of heat. Since you have some soldering iron on hand, you might be able to work around that. Regarding the multimeter, it’s a good idea to get one if you plan to use voltmeters later. For soldering, consider getting a few affordable 60-watt irons and some good quality mechanic solder wire. Sandpaper, wick, and flux are already in your possession, so you’re close. Just make sure you have a proper workspace and maybe a bit of patience for the cleanup.
You can use a very sharp blade to remove the mask from the trace. The solder paste is mainly made from isopropyl alcohol and small solder beads. In theory, you could apply the paste along the length of the cut and then use a low-speed hot air gun to melt it. A soldering iron tip might also work. My suggestion is to invest in better quality instead of cheap alternatives and spend wisely for lasting results.
It's time to take apart another inexpensive shaving tool. I'm trying to figure out where that tiny razor piece ended up after working on my Pentium 4. It seems it might be useful for removing solder mask, but its flexibility makes it tricky to handle. I'm considering using a regular razor instead. I was thinking about spending around $2.5 on an iron, but I'm not sure it will be worth it after just one use—especially since I've already used it on the Giga X58 and some traces. I'm planning to build a heat chamber to speed up drying after water baths, so maybe a solder iron would work better. I'm looking at decent 2.5-watt irons with swappable tips, but I'm more concerned about getting a good heat source. I could also get some $7, 1500W heat guns, but I'll need Kapton tape and a soldering iron. I'm worried the heat gun might be too slow or cause unwanted heating, which is why I'm leaning toward two soldering irons. Reflowing my GTS 250 will require a digital thermometer to follow the right curve, which could take some time.
