Subject: Re: [Homebrew_PCBs] Squink - The conductive ink printer

From: Dennis Shelgren <nojoeco@...>

I personally didn't see anything I would call fine pitch. Also it's clear that the goal was simply conductivity for logic levels only.  But the tech is clearly aimed towards startups and education, and in their favor I think they nailed their goals. However for those of us trying to provide an alternative to commercial board houses, they are a far call away. But I as a startup myself understand it's baby steps. If you hit your initial goals then the potential for better results are always there. Having said that I feel that there are many possibilities for those of use working on boards we'd rather not go through a commercial board house or "new" technology. I'm personally setting up an epson printer with ye old hard to kill magenta ink. But I also have available a cnc mill that could route things, but it's resolution is pitiful for things like fine pitch. I'll probably will go back to some sort of photographic method before I waste too much time.

Heck with it, here's my useless fundraiser.

I'll try to be more active in conversations, being involved in my own efforts to produce "maker" facilities for startups, etc.

Did you see the part on conductivity?

Now calculate the resistance of those 10 mil traces.
