CAIG Labs' PCB Etchant Solution is great for any one working on custom printed circuit board designs. All the mixing is done for you, so this solution is ready for use. If circuit boards are not your thing, it can also be used for etching either metals or ceramics.
You can etch a PCB by yourself, in a lab or even at home, using a simple and inexpensive production process. It makes sense when you wish to produce a single or a very small number of boards and want to avoid manufacturing costs.
Simple Boards - If all you need is a rough board for a limited application, it will certainly cost more to have a third party make it and will likely take longer and be much more trouble than it's worth. Avoid the nonsense and make it yourself.
Total Control - Do you want to make a circuit board out of unusual or extraordinary materials? Either your own creativity or the demands of an application. Do it yourself and the limitations disappear!
Rapid Prototyping - It takes less than an hour to print a PCB yourself, so if you're going through a lot of designs, why wait a week or two for every new prototype?
Art Projects - Board manufacturers have trouble with odd shapes and cutouts and will charge more for such designs. Making your own PCBs opens up a whole world of unique materials, shapes, and applications.
