## Questions & Answers

**Q: Will this work to coat the non-working rubber buttons on a remote control**
A: Yes, this worked great. First, clean the circuit board where the contacts are using Isopropyl alcohol.  I also used Iso to clean off the rubber dot, which is usually a conductive carbon substance.  Then apply the *carbon* version of this product to the black dot.  Cover the whole surface and let it dry completely before re-assembling.

**Q: Can this be used to repair a broken strip in a car rear defogger?**
A: I just tested a 1/2" long x1/8" wide strip on a piece of pyrex glass and got 0 resistance for that length. It seems to conduct well for a short distance and stuck to the glass very well. I hope this helps.

**Q: Does it work for making a PCB?**
A: In my opinion, it's far from the ideal for making your own PCB. I can see it being used for prototyping of low voltage/low current circuits.This particular compound is based on nickel, which is not a as conductive as copper.This pen would work fine for the small repairs like cuts or tears in the existing PCB traces. BTW, there's a more conductive version of this pen which is based on silver.Aside from conductivity issue, there's an issue of securing parts to PCB. I,also, doubt you can solder to the trace drawn with this pen.

**Q: Is this pen good for making a jumper on a circuit board?**
A: Yes, it's great for that but even the carbon conductive (lowest quality) pen would work for that

    Fixed my control panel keypad
  

*by L***K on Reviewed in the United States on October 5, 2023*

I'm very glad this product exists.  Saved me hundreds of dollars!The material flows pretty well once you get the hang of it.  It's similar to a paint pen, but with nickel in solvent.  Let it dry!  It wont conduct until the metal settles and the solvent dries.  It was fun to use a multimeter and watch the resistance drop as the fluid cured.I used this to repair a laminated keypad ribbon cable in a microwave that somehow got a melty trace.  I also used it to repair the damage I did trying to fix the problem before i knew this product existed.  It will now and forever be a part of my electronics kit.  Perfect for membrane trace repair!Adhesion is good on plastic.  The output width is about 2mm.  It's a fluid but not super runny, especially after the solvent flashes off.  Build up a couple of coats for best conduction.It takes a minute to get used to dispensing the material.  The pen uses a plunger valve tip that has to be pushed against the surface before flow will start.  You control the flow with how hard the tube is squeezed.  Wiping the tip after every lift-up makes things go smoother.

    Works great for repairing keyboard membranes
  

*by L***. on Reviewed in the United States on December 30, 2023*

I've been using these to repair the plastic membrane sheets of my IBM and Unicomp Model M mechanical keyboards for several years and have gone through at least three so far. The silver pens are expensive, but I read somewhere that it's best to keep using the same metals throughout, so I buy those.They're not the most intuitive to use, so you should make sure to try it out on a piece of scrap paper or something you're not afraid to ruin to get the hang of it. Always make sure to give it a good shake first (like a paint marker) and squeeze the body while laying the ink down. And if you mess up, even after it dries, it's easy to scrape away with something like a screwdriver or an exacto knife, at least on smooth plastic.My picture is of some traces I repaired on a Model M membrane. I accidentally scraped them off while cleaning away a nasty stain and fixed it using this pen.

    Fixed a corroded circuit board
  

*by A***N on Reviewed in the United States on February 20, 2022*

Repaired a corroded circuit board on a rowing machine, my first time using this product.Pro: Saved me a lot of money by not having to buy a replacement monitor for my rower.Con: Difficult to use.  Comes out in a thick line or blob that isn't detailed enough for use on a circuit board...I didn't get the board perfect as a few lines of the LCD display aren't working, but it at least turns on and works now.Tips: Check each trace for continuity with a multimeter before assuming it is bad, there were several that were visibly corroded but still had continuity so didn't need repair.After repairing a trace, if you still don't have continuity, check continuity to each side of your repair to figure out where the issue is.Use something fine pointed like a toothpick to dab it where it needs to go and scrape off any excess.
