My understanding is that an engraver is like a cutter with less output power. Enough power to leave a mark, but not much more. The level of precision probably isn't implied in either case.
If you are looking at engravers on Ebay, they are probably low power CO2 which can't engrave copper. There are IR and UV lasers designed for prototyping PCBs, but they cost somewhere in the $60k range to get started. There are other options for using a CO2 engraver, I suppose. Like painting on a chemical resist layer that can be engraved off, leaving exposed copper to be consumed by your favorite acid. http://www.instructables.com/id/Double-sided-PCBs-with-a-laser-cutter/ -- Kenny -+---+++-++-++++--+------+-+-++--++--+-+-++--+++-++----+-++-+++---+----+--+----+ On Wed, 2014-08-27 at 22:15 -0700, benjamin barber wrote: > Question: is a laser engraver a smaller and more precise version of a > laser cutter? > > Question: can a laser engraver be used to manufacture PCBs?
