Is it possible to etch PCB's with HCL? Answered
i bought one of ladyada's USBtinyisp avr programmers a few days ago, its working great! i program alot in visual basic but i never tried anything quite like the C similar programming of the avr chips. because of that i reprogram my chip ALOT, so i decided to make a target board. i already have the "blank" board and a UV lamp to prepare it. i have sodium hydroxide to develop it. all i need is something to etch off the copper. so i was wondering: can i etch off the copper with 32% hydrochloric acid/muratic acid/HCL?
