Subject: Re: [Homebrew_PCBs] Length of sunlight exposure of photosensitive boards

From: Tom Biery <judsquare@...>

I've done it not with Injectorall but with Kinsten,  I was able to expose for
2-2.5 minutes of very bright sun.  Works ok but yield is not good.  If you can
tolerate some scraped attempts it might be ok. 


Good Luck, Tom

Subject: [Homebrew_PCBs] Length of sunlight exposure of photosensitive boards

 
Hello, I'm new to this group, though not new to electronics. Does anyone out
there have experience with exposing a photosensitive board through a negative to
sunlight? A man at Injectorall told me that about six minutes at noon on a
bright sunny day but that doesn't seem to work.
