Learn how to do the UV exposure of a PCB: http://www.ozeki.hu/index.php?owpn=2917
Almost done! Here we are at the third part of creating a PCB board! Here you will see how UV exposure works. For performing this process a photoresist coated copper clad board is needed. The photoresist coated copper clad board has to be cut into the required size. Use a shear plate cutter for getting this done. After removing the protective film from the copper board, it needs to be placed into the packet you have already created.
Put the board between two glass plates to fix its position and place them into the UV exposure box. Pay attention to timing! When ready take the board out!
