Product description
The 842AR-P Silver conductive pen is an extremely 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 center of the pen. Applications & usages 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 pcbâ€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. It is 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.

838AR-P – Carbon Conductive Pen
A circuit repair pen that dispenses acrylic lacquer pigmented with conductive carbon. The cured traces are durable and corrosion resistant, with fair conductivity. They adhere well to plastics and most electronics substrates. The valve tip opens when pressed against a surface, and the flow is controlled by squeezing the barrel. The product works best on a smooth, flat, hard surface, but the cured traces are highly flexible.
This circuit pen fixes damaged traces on keyboards, game controllers or remote controls. It is also useful for making small connections, such as jumpers and bridges. It is great for drawing resistors and can be used to increase the surface area of contacts by painting the area around them.
841AR-P – Nickel Conductive Pen
A circuit board trace repair pen that dispenses acrylic lacquer pigmented with conductive nickel flakes. The cured traces are durable, corrosion resistant, and have good conductivity. They adhere well to plastics and most electronics substrates. The valve tip opens when pressed against a surface, and the flow is controlled by squeezing the barrel. The product works best on a smooth, flat, hard surface, but the cured traces are highly flexible.

1. Applying this is tough. The pen releases the paint when the metal tip is depressed. It's very difficult to control the flow rate and often you get more 'paint' than you want of need. In practice it's difficult to apply small, thin lines unless you use masking of some type.
2. If you need to build up areas (two of more coats) for coverage the applicator tends to scrape off previously applied paint.
Despite application issues it does work well and adheres well to substrates. Good in a pinch.
It also smells terrible so use in a wet ventilated area and I'd avoid getting it on your skin just for good measure.

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.
Laid it on fairly heavily over a broken trace for the keyboard membrane. Testing conductivity a few hours later it did not look promising. Testing provided no improvement. So I put it in to the pile of disappointment and sorrow. A few days later I thought lets try it again but low and behold it was working! I guess it takes a few days to properly cure.
Phew. £140 saved!
But when I used it, soon the tip got blocked and no more ink was flowing. So I had to cut open the body and use a small stick to scoop the ink and paint.
However, ink is good, dries fast, sticks well on plastic surface.
I ordered it to repair keypad of an old spectrometer. We saved around 1-2,00,000 rupees.

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.
