Easy to apply and conductive. It's not metal conductive since it presents tents to hundredths of ohms resistance but gets a small repair done

No es para cualquiera, pero debes de saber cómo aplicar el producto , para realizar trabajos es muy bueno , perfecta conductividad y muy bueno porque lo ocupo para trabajar las membranas de los hornos de microondas y ninguno tuvo falla ... Todo muy bien ,comprare otro 👍

Kann das produkt nicht guten herzens weiterempfehlen. Ist zwar conductive, aber das ist ein gaphit bleistift auch. Auf 1cm strichlänge hat man schon 120k ohm widerstand, bissl weiter gehts in den mega ohm bereich. Der widerstand is so gross, das man nichtmal bei 2mm linie einen ton aus dem multimeter bekommt wenn man auf durchgang testet..kann nur widerstand messen. Mag vielleicht bei nem kratzer auf ner pcb leiterbahn helfen um zu überbrücken..mehr aber auch nicht. Bei dem preis gibt es bessere möglichkeiten ein pcb zu fixen.

I had a few remote controls where most of the keys stopped working due to the carbon wearing off the membrane pads and not making sufficient contact with the PCB. Putting a blob of this carbon compound on the carbon pads of the membrane fixed the problem entirely. A few tips; - wear gloves, this stuff is messy and carcinogenic - shake the pen for 30s - use a sheet of paper to clean the nib - make sure the surface is clean, IPA+cotton bud - leave for 24 hours for conductivity and strength

Works good, used to fix a trace on the pcb in my car’s cruise control stick. Only gripe is that you can’t really control how much comes out very well. Also note: whatever you’re doing / fixing won’t work until the ink has completely dried. Found out after 30 mins of pure worrying that I’ve wrecked the pcb I was working on.
