Well I have seen etching on steel with 50% boric acid and 50% water so it should eat copper.
I have etched PCBs with pickle juice.
Hahaha thank you for your answer. I have 3% boric acid, maybe I can use some ratio with water and HCl. I will try it today. Thank you.
As much as I thought it would be a laugh the pickle juice etched the circuit.
Try copper chloride ;)
Ok, but I was asking if I can use boric acid for etching.
