Re: [DIYbio] microfluidic chips to order

I was actually speaking with an EE friend about just such a concept.
The smallest trace can go to about 7mil but it would be about 1-2mil
tall. He said using solder reflow could round off the channels. I made
a few shrinkydink chips with some success as long as the channel width
wasn't too small and only one layer. Dakota, if you want just send me a
hand drawn sketch and I'll make one for you in PDMS and pop it in the
mail for free. I have a ton of PDMS and shrinky paper so I don't mind.
I use DraftSight from dassault systems but AutoCAD is best for super
high res chips. Shoot me a pic of the chip u want. What's the worst
that can happen? :P

No idea, I just recall seeing it discussed! :)
Looking at this handy adafruit ruler though, trace sizes can get pretty
small.. looks like 0.2mm on this ruler, and I expect they go lower with
some companies.
