Nobody ever created a reliable self-contained foolproof PCB etching procedure. That's why nobody etches their own PCBs.
If there was a box that received supplies and outputted usable PCBs with minimum external mess, a lot of people that currently buy boards would use it instead.
(And well, PCB manufacturing is basically the same process as chip fabrication, without the miniaturization. If nobody managed to create a "PCB printer", why do people keep hopping for a "chip printer"?)
- kragen 2y agoEtching your own PCBs has been a common electronics hobbyist activity for 50 years or more. Un-etched one-layer and two-layer PCBs were a standard stock item at every Radio Shack. Local electronics stores stock ferric chloride etchant.
