Question related to photo-developing boards

Community PCB Design

Fairly simple question. Do you have to buy the pre-sensitized PCBs, or is it possible to sensitize the PCBs yourself? I can’t seem to find a definitive answer…

Thanks,

You can photo-sensitise boards yourself, using an aerosol (Electrolube, IIRC) or dry film. The aerosol used to work, but it was reformulated and the current material is useless. Dry film only makes sense if you are doing a lot of boards. I just buy the pre-sensitised boards.

Alright, thanks :slight_smile:
