Build your own UV exposure box with fluorescent like lamps
 

Ever wondered having your own UV exposure box in your lab but couldn't get one because of the high cost? Don't kill your dreams so easy. Now you can make your own UV exposure box and print your own printed circuits boards in your home. In this article we will find out how to construct the appropriate box and the required electronics inside it. This is a basic guide and not a super detailed guide. Many easy to understand thinks are missing. Don't loose more time, let's start with the specifications.
