Hi all, I've never etched before but I want to make some simple pcbs.
I brought a kit from a high street store that contains a bag of sodium persulphate powder or crystals whatever.
Is this the same as ferric chloride? If not is ferric chloride better to use?
Also, once I've mixed up this sodium solution, will I be able to keep it in a plastic container and re-use it?
Thanks
