Thanks for posting this! I found it on the eevblog forums, and it led me here... the airlift pump idea is brilliant for handling Ferric Chloride and I haven't seen it done anywhere else... it keeps all the metal bits well away from the ferric chloride, is low pressure and very reliable. I'm re-mixing the design a bit for assembly using laser-cut 6mm acrylic and a commercially available etchant tank, and will share details once I've got it built and tested. Hope it's okay if I credit you in my remix?
Hi, due to many requests I decided to make a more detailed step by step guide, how to set up and run this machine. The documentation is now ready for use. Simply contact me via the email address shown in this clip if interested...
Hello, I am interested in the pdf guide for the construction of the 43x20 pcb foam machine. You can share the construction guide, it is for didactic use, greetings and excellent design.
OK. I obviously didn't watch the video properly as of course it's DIY. I have no problem with that, but do you have any plans, parts lists etc.? Tried to email but your address fails!
Currently, space allows for PCB up to 13.0 by 13.0 cm, which is enough for me. With scaling up the whole upper part of the unit while keeping the same etchant pumping system, maximal PCB sizes of 30 by 30 cm should be no problem at all.
Yes, both sides get etched at same time in one go in best quality. Because etchant flows below the board too. At 25 Celcius it takes less than 4 minutes (with fresh solution of course)
Hi, yes, you can see it working with FeCl3 if watching the full clip. The pump is actually the 20mm PVC pipe itself. So it's not possible that particles block it. Best regards
Michael Pereira Cool, very nice project. Any brand ,specs on the pump. We only have 230~ ac here. Is the flow rate of the pump adjustible. I'm not familliar with aqua fish pumps. I would like to build one and use it with FE3CL
Hi. All simple air pumps from your pet shop with at least 5 watt power will do the job. If needed, you could reduce the amount of air simply by squeezing the air tube. For more details you better drop me an email so I can reply
Hi, I made an improved version of the machine. With better design, easier handling, less material. And for.much larger PCB. Watch images on eevblog / manufacturing & assembling.
I think your design is awesome Michael, thank you for posting. Excellent video.
One of the best ideas I've seen in ages. Plus, you can just let it run for entertainmen when you're not using it t!
the music is great! good job!

Any new idea or improvement (specially if shared) will be always highly appreciated ;-))
une machine originale dans son architecture,bravo !

please send your email address to me (micha110280@gmail.com), so I can forward the PDF. Regards
Hi, Michael. i'm very intrested too ) I sent e-mail to micha110280@gmail.com
OK. I obviously didn't watch the video properly as of course it's DIY.
I have no problem with that, but do you have any plans, parts lists etc.?
Tried to email but your address fails!
Via this email address I get all YT notifications as well. Therefore it should work. Please try again.
Just a couple of questions.
What is the maximum size PCB is it able to make?
Where are these available?

You didn't answer the second part.
Where are they available?
Have you tested it with double sided boards?
EDIT: yes it does
Yes, both sides get etched at same time in one go in best quality. Because etchant flows below the board too. At 25 Celcius it takes less than 4 minutes (with fresh solution of course)
does this also work with fe3cl ferric chloride . does the pump not get full off particals like fe3cl and copper restands.

Hi Michael I'm very interested) Is it still possible to get a file?
Yes, I'll send it to you if you drop me a line to my email address given at the end of video clip

can you send the link? I want to see those images
Hi, drop me a line to my email address shown in this clip. I'll send you more details as pdf file
hey Michael Pereira . can u send me a link in my email
