I won't be bothered to place a wire when the gap itself is less than diameter of that wire. On good half of these cracks you can get away with just a solder blob.

For burning the enamel off the wire, dont hold the wire in the lighter flame, you run the lighter back and forth very quickly for about 2 - 3 seconds then instantly wipe, and the coating is burned off with no melted wire. Also for these repairs, use air dry pcb an solder paint, with a couple of coats of UV-curable solder mask on top. No actual soldering required because the sokder paint joins the gap. And, a sewing pin stuck in to an old thin artist brush handle (remove the brush head, drill a tiny hole in to the brush handle, then insert the pin, sharp side facing out, superglued in- could possibly use a thick BBQ wooden skewer instead of the artist brush handle) is a better tool for scraping the solder mask off the traces. It also gives you more control and it makes sure you wont cause any extra broken traces.

for some reason youtube recommend me this video. Great video and new subscriber here

The funny thing about magnet wire: If you're using it for patching a trace, then you want what is normally considered bad quality so that the enamel is removed easily. If winding a speaker coil or radio tuner or inductor, etc, you want the BEST quality wire so that the enamel doesn't flake off so easily.

The fiberglass pen that I use has a smaller diameter fiberglass element . Possibly the broader size pens like that cover too much area for such a job .

Good stuff mate, just started the same thing, first video coming up soon. Let me know if you want to chat about it... In the meantime I just got hundreds of cassettes and games...but nothing makes you feel better than a repaired sega cartridge!

Great job on these! If you replace that flux pen with some genuine quality flux (amtech is great) it will make a huge difference :)

huh magnent wire for enamel wire. i learned something. never crossed my mind.

Great video ❤❤❤

18:12 with such a solder blob on a contact pin you are going to destroy your cwrtridge slot as it will bend the contact in the slot.

subbed. keep it up.

Good job! One more subscriber!

A trick that I like to do to expose the copper underneath the mask is to take an xacto knife and scratch away at it. I'm interested in the engraver pen, but my method works for me and I'm cheap lol.

That mono made me check my headphones ...

@HopefulRepairman what catastrophe caused this damage?

what solder are you using

I can see the reflections of the LED lights you got going there yet the image is still too dark. fix the exposure setting on your camera.

By cheap Sports games and swap the rom chips

you need more flux.

I have used fiberglass pens many times. I don't know why you are freaking out 🤨
