Mix this Sodium Hydroxide Powder with Water to make a PCB Developer that will develop your custom Printed Circuit Board (PCBs) with ease. Just dip your copper clad board with photoresist in after UV exposure and you'll get precise copper traces where you want and all the rest of the unexposed photoresist will melt away! It is clear, so you can see your PCB as it is being developed and monitor its status throughout the process. Making a PCB Developer Solution with this powder also requires no heated baths and produces nearly no fumes! Make your own printed circuit boards like a pro with this 4oz bottle of PCB Developer Powder!
