The ProtoLaser S selectively ablates the copper layer from the substrate to create planned tracks and pad surfaces. Learn more: http://www.lpkf.com/products/rapid-pc...

The LPKF ProtoLaser S produces precise geometries on a whole range of substrates such as copper-clad FR4, aluminum-coated PET films, ceramics, Duroid and PTFE.

The laser machine is more precise than the mechanical systems and is therefore ideal for RF and microwave circuits, as well as digital and analog circuits.

The wavelength of our lasers is 1064 nm, which is equal to infra-red. The wavelength of the ProtoLaser U3 is one third of this - 355 nm. Actually we are not using any photoresists. This is done by the user itself. The LDI is structuring the resist. Afterwards the exposed copper is being etched. You proceed like this with respect to very thin structures. The laserspot is only about 1µm.

It's a shame that machine costs around 75.000 USD

How much more conductive does the FR4 become where the copper has been removed?

What is the wavelength of this laser? It seems you did not specify that in your brochure. And apart from that, which photoresists do you use when structuring PCBs with your ProtoLaser LDI product? It looks incredible I have to admit :)

yeah, it will be too much. We can convert our desktop cnc machines to do nearly this. The accuracy of that laser is pretty amazing tho.
You know what they say, if you have to ask then it is too much.
but this cuts the copper ?? or just mark the surface ??
Can this machine works with flex pcb??

at 0:44 wow I want one for home!

What's the best resolution for the tracks, in th (mil)?
