Subject: Re: [Homebrew_PCBs] darkness requirements for UV PCB handling?

From: Randall Morgan <rmorgan62@...>

Most in-door lighting does not produce enough UV to cause an issue. However, if you have one of those full-spectrum or daylight lamps beware. I actually have used my daylight desk lamp to expose board. Also Halogen lamps may produce measurable amounts of UV so I suggest turning them off. Otherwise, normal room lighten is fine. Even during daylight hours as most home windows filter most of the UV out of sunlight coming through the windows.

I usually just unscrew the one bulb over the bench and the remaining
light in the basement doesn't seem to affect it significantly.

If you ask me if it can be done. The answer is YES, it can always be done. The correct questions however are... What will it cost, and how long will it take?
