This can become a problem; if the process is not tightly controlled, the etching reactions can extend underneath the resist layer masking off areas of the future traces of the PCB, potentially ...

Personally, I dread the thought of etching my own boards. The process is laborious and involves messy chemicals and specially sensitized PCB’s — none of which interest me. I’ve only ever ...

DirectDrive generates plasma with 100x faster responsiveness than previous sources, resulting in fewer patterning defects ...

but slower chemical etching is faster and cheaper, but uses hazardous chemicals PCB design involves placing components, creating tracks and pads, and using design software PCB amendment involves ...
