Does the job without the mess
Reviewed by: Mr Scott Britchford

When I started making my own boards for quick prototypes, I originally used ferric chloride. Whilst it etches, it leaves one hell of a mess so I tried this stuff. It's almost odourless (very faint odour of what smells a bit like bleach), colourless, doesn't stain, and its clarity means you can see when your board is done. It turns a nice pale blue as you etch until it gets to a sea-blue when I suspect it is saturated with copper and etching becomes painfully slow. Totally worth the price because if you're making lots of boards and need to save money, its cheaper to get them made professionally - but if you only make a few boards at a time this is the stuff to use. 5mil traces are achievable and it doesn't seem to etch under the etching mask.
