laser on presensitized
2008-10-20 by Cristian
Cheap UV 100mW cw lasers (BluRay) on eBay. It emits on 405nm, but some presensitized pcb (like Bungard's/Germany) responds to that light. Good to replace the CNC PCB Machine's tool (to get the traces registered with the holes) , or the plotter's pen. See my idea/calculations in the group's archive # 7191- #7213. Cristian
