About PCB Etching

Whether you work with electronics or use metals for artwork, you can find a good use for PCB etching solutions. A printed circuit board (PCB) is made from a copper sheet laminated onto a non-conductive layer; copper has the highest electrical conductivity. The circuit board electronically connects components using conductive tracks and pads. When you are creating a circuit pattern, you need to etch it onto your copper sheet first. Some electricians and hobbyists use a marker pen or photo paper that they can peel and press onto the sheet. Reliable sellers on eBay list ferric chloride solutions, which are permanent black inks. Look for easy-to-use solutions in the right strength, so that you do not need to dilute them. Always wear rubber gloves to prevent staining the hands. Prepare the outline of your circuit on the copper sheet, then dip it into a non-metallic tray filled with the solution. When the etching appears, simply place the copper into a bowl of water to stop the etching reaction. You can also use PCB transfers to create artwork on copper sheets. With PCB etching solutions, you can create your own electronic circuits and unique art.
