I meant that it would deposit on a cold piece of your circuit board, unless you have really good ventilation to remove it immedately (at which point it will probably deposit into a hose that sucks it away or something. Copper vapour would certainly condense, and fine copper particles may also stick to things.

Obviously you should never inhale those, i'm sure that it would be pretty hazardous.

Avoid necroposting on dead threads--frowned on here---last post and interest here was 1 year ago

Consensus seems to be an ordinary laser diode won't cut it (literally). You need something like a Q-switched laser, pulsed at 10's of kHz. The peak power has to be extremely high to ablate copper (>2500C), and some nasty fumes come off the epoxy substrate, which have to be exhausted. Even a 40W CO 2 CO2 CW laser won't cut thin metal foil- it just bounces off. See: https://electronics.stackexchange.co...layer-from-pcb

I had already read that,
At the beginning of this thread, it was asked that someone who had a powerful laser, try to remove copper from a pcb ...
I do not want to buy an expensive 15w laser, if that is not going to work for me ...

Thanks

IDK, changing my view, I've searched the web for information which led to a forum I was completely unfamiliar with and posted a question in an old thread before. They didn't like my necro-posting, but I found the thread on a google search. Maybe legit question..

yes could be that.

He has an answer of a sort--will not work is the consensus---reflective metals, are difficult to laser cut using CO2 lasers include yellow metals such as gold, copper, brass and bronze.

"In this work various problems concerning cutting copper sheets using CO2 laser are reported. First, all copper thermophysical properties, that regulate the process dynamics, and then the weight of each parameter has been evaluated numerically, even though only approximately. The surface absorption value of copper at room temperature and near the melting point and the order of laser power that is necessary to cause a gradual raise of the workpiece temperature from room to melting have been estimated. Then, the order of the cutting speed at which a sheet of a known thickness can be cut has been calculated. The analysis of all these problems, and the process dynamics and state of the art seem to confirm the validity of the current thesis on the impossibility of cutting copper by CO2"
From: Cutting copper sheets using CO2lasers | SpringerLink

Another but more hopeful about copper:
"During a decade and a half of industrial applications with carbon dioxide lasers, many different materials- metallic and non metallic have been cut by C02 lasers. But the basic physics of laser beam absorption and subsequent thermal conductivity involved in the cutting process have made a few materials poor candidates for laser cutting. Copper, in particular, has long been thought uncuttable on a practical basis. We have successfully cut copper sheets ranging from 0.2 to 4.0 millimeters thick with a 2 kilowatt CO2 laser. The processing speeds can be significant : micro-graphic sections of the various work-pieces show that the laser cutting quality is quite good. This article consists of two basic sections-a brief review of the process dynamics of laser cutting and a discussion of our experimental results. For simplicity of expression we will refer only to metallic work-pieces in this discussion. "

This is not a necropost, but I am putting it here because the webcast, by Laser Focus World, and sponsored by Ophir, II-VI Incorporated, Lasertel, and Eagleyard Photonics called "Understanding High-Power Laser Diodes" included a part about copper absorption at 450nm wavelength which reminded me of this thread.

I outlined why you would need either a q-switched or massive kilowatt scale laser to do this over a year ago in the initial few posts. A 15W 450nm laser would be hopeless for copper ablation.

Yeah, I saw that post, but I had to put this somewhere and the CW 450nm laser they were talking about for copper made this seem like the best place for the link to the webcast. It wasn't about that so much, but that did catch my attention and seemed like information someone looking to do this would find interesting.

Yeah. No worries. Just wanted to make sure that the original necroposter got a clear message.

Default Re: Direct laser PCB etching (through Cu ablation)

I'm not reallly sure what the point of it woud be.

Directly blasting off the copper probably is not the best of ideas, but you could use 405 nm lasers to illuminate the photoresist layer or normal pcbs and them develop and etch them as usual.
