UV laser

This work was done by Svavar Konráðsson check out more of his work here

The new UV laser is giving us amazing results in Fab Lab Ísafjörður . Trace width down to about 0.1 mm and it cuts the board outline without charring! This is the future of PCB production in Fab Labs.

Neil's hello.t3226-MU board, which has an ATtiny3226 in a tiny VQFN package, was scaled down for the first test (see the set.xcs file at the bottom of the page), and then scaled down again until its longer edge was only 6.5 mm. And it works! See the smaller_set.xcs xTool project file. At the bottom of this page

The UV laser enables us to use pretty much any tiny modern component, except for most BGA (ball grid array) packages, because we can't do in-pad vias.
