Minimum feature size of 12 mil can work. Be sure to use ground fill planes in order to minimize amount of material to be removed by laser and etching.<br /> <br /> * Prepare the board by coating with flat black spray paint<br /> <br /> [[File:Black_spraypaint.jpg]]<br /> <br /> * Export layout as a 600 DPI black and white bitmap. Invert the image as the black portions will be cut away by the laser.<br /> <br /> * Load bitmap into Corel Draw.<br /> <br /> * Configure laser to use 19% power and 50% speed with 500 PPI and raster scan.<br /> <br /> * Laser cut away paint.<br /> <br /> * Scrub away burnt region using toothbrush and toothpaste<br /> <br /> * Success<br /> <br /> [[File:pcb_laser_test2.jpg]]<br /> <br /> <br /> <br /> <br /> ----<br /> <br /> ==Router milling==<br /> <br /> Using a CNC router to perform isolation milling<br /> <br /> ----<br /> <br /> ==Etching==</div>
