DIY Photolithography

Image
DiyouPCB  The printer has been designed to use any photosensitive material to the laser wavelength (405nm) although the tests were performed with  negative  Dry-film  (blue color). Print area:  210mm x 170mm Laser wavelength :  405nm Auto-focus:  through astigmatic method Diameter of  focused  laser beam:  approx. 0.1mm Print speed:  600mm/min. Travel speed:  max. 15,000mm/min. Dimensions:  385 mm x 345mm x 100mm Weight:  approx. 2.6Kg Power:   110V/230V, 50 - 60 Hz, 2A PC Requirements:  Microsoft Windows XP/Vista min. 1 GB RAM, min. Graphics 1024 x 768 pixels, USB 2.0 port. Electronics:  based on Arduino ONE Development ­­­­­­­ We used the famous  Toshiba  PHR-803T  Blu-Ray™  pick-up  (really it's HD-DVD) . We though we could use a  Blu-Ray™  pickup laser  diode to sensitize  Dry-Film : a photo-resist material very popular to print PCB's. Dry-film is easy to...
