Re: PCB Eyelets
Dwayne's advice is dead on. It works really well. The only problem I've ever had was the wire-wrap wire coming unsoldered at the top, and that was because there was another pad right next to the

Re: PCB Eyelets
My usual way to fix a board with a missing PTH is to either simply patch from the pin to the next closest node on the bottom of the board **or** scrape the solder mask from the top-side trace, run a

You might try www.beaducation.com. I purchased items on there to make a switch. Nice folks to deal with. 73, Charlie, N0TT On Sun, 10 Jun 2018 16:31:42 -0700 "Jim Pruitt"

Hi guys Check this out from Marco Reps https://www.youtube.com/watch?v=1hFNj86L7sk&t=42s All his videos have some great info. He has PCB laser etching nailed. He's done this one and some following

Re: Means of going from a pdf file board image to a file to engrave from?
Sorry, it looks like I was wrong about Pulsonix being able to convert from PDF to Gerber. It does work the other way round, but that isn't much use. Leon

Re: Means of going from a pdf file board image to a file to engrave from?
The Pulsonix PCB software I use can convert PDF files to Gerbers. I could probably convert that file for you. Leon

Re: Means of going from a pdf file board image to a file to engrave from?
You can convert the scanned image to a vector image, the vector can be used to run the engraver. Eg: https://www.dropbox.com/s/x9qc7bqdt3m9l9x/traces-bw.dxf?dl=0 That was done using CorelDraw with

We¡¯re not dealing with thousands of watts like the ¡®experts¡¯ who always chime in think we are, you don¡¯t need much power to burn off paint. Like the earlier link said he only used 2 watts.

Glass tube? What resonator? With flying mirrors? Ain¡¯t gunna happen. We¡¯re not cutting either, so the beam is going to get reflected back all the time. Still ain¡¯t gunna

Re: Seems like we moved + pcb fab idea.
Still wouldn't use a CO2.? Back reflections are the issue. Ever see a resonator after the beam goes back into it? That happens at the pierce or etching (which is what you are doing).? Once the cut
