## Description

CircuitWriter Conductive Ink, silver-based, 4g

Review: Work - Work fine
Review: Repaired membrane keyboard trace. Dried and usable in 20 minutes. - I bought a Corsair K57 keyboard for my wife. My cat barfed on it three weeks after I bought it for her. The cat barf was enough to corrode the flimsy, uncoated traces on the flex ribbon underneath the keyboard membranes. It wasn't the membrane press parts that corroded; it was the trace wires connecting to the press pads that corroded, but this product should handily work in either area. I used this pen to coat the corroded traces, and much to my surprise, it actually worked. The paint goes on about as thin as you can expect it to go on, so it will work with fine traces. It does not dry clumpy or leave a thick mound. It's very thin but dense, which is probably good. The paint is a shiny silver color. It's not the dark carbon color you see in other varieties. If you bridge connections you did not mean to bridge with this pen, you can use an exacto knife to scrape away the excess paint. The paint scrapes away fairly well and does not cause big chunks of the trace to break away when scraped. You can use a ~40W incandescent desk lamp to make the paint dry very quick rather than waiting for it to air dry over hours. I've never used the more expensive versions of this type of product. I paid ~$25 for this pen and I imagine the $45 versions aren't much better.

### ⭐ Bad batch or expired
*by R***Y on 23 October 2020*

I've used this product in the past, it always worked very well for membrane key matrix modifications. The pen I ordered here in Sept 2020 results in 24hr cured traces with very high resistance, which varies, some lines have no conductivity at all. Caig is a good company, and says this one Caig product is fery shelf life dependent. Caig does NOT have a production or use by date on the pens. If they did this QC issue could be avoided. They said they would send me a replacement, but I wanted to post a warning. All my modified membranes are now junk. I didn't use or test this pen until just 4 days past 1 month so Amazon's great return policy didn't apply. I will only buy these directly from Caig in the future.
