DIY Photolithography
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...
