Calum's demo used MICROTRAK single sided boards, in 35um copper thickness, 1.6mm thick board. You can buy them here: http://www.megauk.com/pcb_laminates.php though I think they have a minimum order, rapid electronics also sells them. Exposed to the UV light with an acetate stencil printed at any random shop for 6 minutes. Developing and etch times will vary depending on temp and some other factors - but 2.5 minutes for developing is a decent place to start, and 10-20 minutes for etching. | |||
