The laser I use can cut through 1/16" acrylic like butter and more: I would not worry about issues with ablation due to uneven coating.
The more important question is: how much do these photoresists cost?
I recall the DuPont sheets from 2003: I was considering them due to the bad toner...
Unfortunately, Krylon has been tried and it does leave a very thin layer of paint residue on the copper that will block the etchant solution from working properly.
This issue is documented here : clean up the board
Would you suggest some other brand or type that is not likely to leave residue...
Only cutting, not DLI.
Nice idea. I am not sure whether using the photo resist used for UV exposure would be a good bet.
Also, working in a dark room with a laser cutter would be difficult as these machines are in a techshop.
This is really a great idea! Any links to general stores that...
The idea of using a laser cutter for DIY PCB is to spray some kind of an etch resist - like an automotive primer - onto the copper clad.
Then, using the laser cutter, remove/expose the portions that you would like to get etched using the etchant.
The end result, what remains would be a much...
I am interested in knowing how many of you have experimented with a laser cutter for DIY PCB?
Would love to hear what kind of experiences you have had.
This method does away with worrying about a laminiator and laser printer but in this case too, just like toner and paper's critcal for toner...
@ckshivaram: Thanks. I see you are very interested in wireless communications!
Would you happen to know some useful, but cheap boards/dongles that we can use in our embedded designs?
Something we can buy from eBay, SparkFun or the like.
I bought a few of those $2 external Bluetooth USB dongles over ebay, and would like to know what chipsets they use.
1. Short of physically taking them apart, is there any software tool that can show me this information?
2. I would like to connect the speaker and mic of my Bluetooth enabled...
