Silver Conductive Paste - Wire Glue Paste Paint Pen for Electronics Repair (0.2ml)

I just received this specialty "glue" and have only had time to use it on one simple repair. Let me start by stating my effort to repair the "traces" on the end of a "ribbon cable" was a failure. But I don't believe the glue itself was the reason. As is pretty much the norm, these traces are small, but more importantly, they are very close together. I started by attempting to lay-down new replacement traces in place of the worn ones, but these are so small and narrow that even using the hypodermic-sized dispensing needle I couldn't keep the individual traces from bleeding into each other. I did discover that I could "clear" areas between the intended new trace lines by using a bit of sharpened "peg wood" (look up peg wood for watchmaking). Unfortunately, all it takes is a small slip in clearing these spaces to drag the peg wood across one of the new traces to accidentally remove the last vestiges of the original trace. Doing so breaks the trace once again, putting you right back where you started. If this was a standard ribbon cable you could remove some of the insulation coating and move the new trace further up to reconnect, but this cable is inside a PC mouse, and it gets connected by pushing the cable end into a ribbon connector socket that is narrower than the cable. The cable's end fits because as the traces reach it, they literally are compacted to get thinner and closer together. Long story short: I believe this conductive "glue" is a viable repair product. I can see it working on many of the circuit boards I've worked on (and will be in the future). I did note what could be a problem, but I don't have enough experience with the product yet: When I slipped with the peg wood, dragging through the still wet glue, I was going to wipe the cable end clean and try again. But when I gently wiped the cable to remove the glue, all of the traces I'd applied it to where literally gone. There were a few bits left behind, but it really appeared that the glue had "dissolved" what was left of the original traces and were then wiped away. This is possible, as I don't know how traces in a ribbon cable are applied so that they adhere to the plastic. Whatever the case is, I believe this is a good product with a lot of potential, and had nothing to do with the failure of my repair. (For what its worth, I'm waiting for delivery of a "parts" mouse so I can scavenge a "new" ribbon cable. Yes, this is a special mouse and hasn't been manufactured for many years.)

The conductive paint itself works fine. The syringe doesn't - it is very difficult to dispense through the needles, and in fact the syringe just pushes it off if you push too hard. Plan on applying it with a very fine brush (you won't need much) and harden with a heat gun for a bit. The repair should be covered with kapton tape. Other tips: be sure to clean the traces you're bonding it to, preferably with De-Oxit or similar. Also, this stuff is bad for plastic - it will dissolve/mar plastic surfaces if it drips on it.

This stuff came with unclear instructions, making it difficult to use, it was not re-sealable, There was not hardly enough paste in this tiny syringe to make it worth it, and worst of all it didn't work.

The title with “paste” is deceiving. This is more like a paint, not a paste. It coats but does not bond. A soldering bead connecting a transistor to an electronic power supply board on my humidifier got loosened after the power cord at the base was stepped on. I used this product to repair the connection and it worked like a charm initially. After just a few days the connection loosened again. The second time I used this paint, I added a bead of super glue over it once it dried. That did the trick, and I have had no issues after 2 months

I have a Gem Car (electric) and it quit going fast, slower and slower. I got the service manual and found the problem with the gas pedal or throttle. The unit was sealed but I unsealed it and found the crack in the trace. Put two layers of the conductive paint and worked like a charm with like .02 ohms and set hard as a rock. Saved about 400 bucks for a rebuild. Thanks

I too was disappointed when I found the chinese only instructions but thanks to Google Translate here they are. The other disappointment was as others have posted it's not an adhesive or even a self drying paste. It requires heat setting to 305F for 5 minutes. I'm trying to patch some ear buds so I'm not sure how they will take the heat but I have nothing to lose at this point other that the $7.95 I spent on this product. I might be able to just hover over the spot with a soldering iron long enough to set the silver. Fingers crossed!

The silver conductive paste is too thick for the syringe needle. Too much pressure needs to be applied. This leads to the needle popping off and the silver paste going all over. I do not recommend this product unless a better delivery mechanism can be devised.

I had a TV/Receiver remote control that the volume and on/off functions stopped working because the carbon conductivity on the underside of rubber buttons had worn off. I did not need a full bottle of electric conductive paint so I ordered this small amount of silver conductive paint/paste. I did not use it as a paste, I only used it to paint a spot on remote buttons to get conductivity again. It was easy to use [I did not read directions] I simply squeezed out a dab then blotted a piece of paper towel to apply to the rubber pad, I let dry for an hour or so, reassembled the remote control and it worked again.
