## Overview

The MG Chemicals 841AR-P Nickel Conductive Pen delivers ultra-low resistivity (0.0040 Ω·cm) conductive traces with a quick-dry formula that adheres to a wide range of substrates including plastics, metals, and 3D printing materials. Ideal for professional repairs and prototyping, it enables durable, corrosion-resistant electrical connections with a precise 1.0 mm trace width, making it a must-have for tech-savvy makers and engineers aiming to fix or innovate with speed and reliability.

## Description

The 841AR-P Nickel conductive pen is a highly conductive, fast drying paint in a convenient pen format. It quickly and easily creates durable, reliable, corrosion resistant, and highly conductive traces. It adheres To A wide variety of substrates. This product works best on smooth, flat, and hard surfaces. It has a valve tip that opens when the pen is pressed against the surface to be drawn on and it has a soft tube, so the flow may be controlled by squeezing the centre of the pen. It is used to draw traces on circuit boards or to create simple circuits on a variety of surfaces for prototyping, hobbies, or Maker projects. It can be used to repair damaged traces on keyboards, game controllers, remote controls, mixing boards, and pcb’s. Repaired devices may be returned to service in only 10 minutes. It is also great for making small connections in or between circuits such as jumpers, through-holes, bridges, and links. It is also good for increasing the surface area of contacts by painting The area around them. Also great for filling gaps in your EMI/RFI shielding. Attention Shake rigorously before use. For best results hold pen at angle, depress pen tip against surface, and draw pen across surface while gently squeezing middle.

Review: Excellent to fix broken remote controls - 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
Review: Works well, needs time to dry - 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.

## 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

### ⭐ Not conductive, but can make a lovely resistor with it
*by D***H on 21 April 2024*

expected this to be conductive like the description said. But it's not. It has resistance. So not suitable for what I needed, repairing broken circuit traces. This is similar to the carbon in a solution products you can buy at car shops. Not recommended. But it does dry quick.
