Copper PCB vinegar etching

[ash4781]

Hi,

 

I'd like to ecth some pcbs for an audio power amplifier but lack the equipment to handle strong acids.

 

Has anyone ecthed pcb's with vinegar as an alternative to the acids, and ferric chloride methods ?

What equipment are you referring at. Simply take a plastic tray, or a glass oven-scale and put your PCB in that, together with the etching liquid.

 

Using vinegar might work, but it will be painfully slow (days???).

I agree with woelen, using vinegar could take days (maybe even weeks) before your PCB are etched significantly.

 

Using ferric chloride would be the easiest way, no special equipment is necessary, a plastic tray of even a glass casserole dish would be fine.
