What's next for me is to design and build a small tank with a reel mechanism that will dip the stencil and pull it out at pre-programmed intervals.

 

Thanks for sharing!! I haven't tried stencils yet, but have found HP Premium Presentation paper works good for PCBs. I does leave fibers behind that need to soak to get them to rub off between traces, but otherwise I've never had a problem due to the paper itself.

I stopped using presentation paper eons ago... now I use the backing paper of commercial vinyl film.

Excellent idea, Danko... thanks for sharing . I'll give it some thought. Best part is that the tank would be so small that I could 3d print it!

Thanks again!! I guess I tried making you go back in time a bit there. Lately I don't do enough to justify the cost, but will for sure keep the thought in mind.

 

Update.

I've just discovered that placing the glass container with a mixture of 50-50 muriatic acid and peroxide under the heat (177°C / 350°F) of my heat press very significantly accelerates the process and also results in a much finer and higher resolution etch.

​

This recent discovery is definitely a keeper.

 

That looks amazing
