LITHO is a compact, self- contained and fully automatic printer with an embedded touch- screen computer. A circuit pattern can be transferred within just a few seconds, and the whole board up to 4" x 4" can be made within 15 minutes and costs just $2-3 dollars, when and where you want it! Additionally, small circuit features can be printed with very high resolution. Smallest feature and pitch separation can be as little as just 8 and 24 mils, respectively! Furthermore, LITHO is fully compatible with both rigid and flexible substrates (e.g. FR-4 and kapton films).
