I'd NEVER get a tqfp 64 drawn right.

 

"We trained hard... but it seemed that every time we were beginning to form up into a team, we would be reorganized. I was to learn later in life that we tend to meet any new situation by reorganizing. And a wonderful method it can be of creating the illusion of progress while producing confusion, inefficiency and demoralization." Petronius Arbiter, approx. 2000 years ago.

Quite impractical in today's componentry world.

The EX1 - rapid 3D printing of circuit boards

by Cartesian Co.

https://www.kickstarter.com/projects/cartesianco/the-ex1-rapid-3d-printing-of-circuit-boards

Uses ascorbic acid plus silver nitrate.

Can also print on plastic film, paper, some etc.

0.635mm (25mil) pitch might be TBD.

What is the minimum size (of trace / gap) that the printer can print?

Pretty sure the pen would be dried up before I got anywhere close to getting my money's worth.

Many years ago...

 

Circa late eighties , early nineties.. I used to attend NEPCON west in Anaheim.

One year a system based on conductive polymer was demonstrated and then promptly disapeared from the scene.

 

In essence a milling process was used to establish a layer of nets an pads in copper.

This was augmented by extruding a thin conductive insultating path on top of whihc a conductive thread was laid.

 

Next stage was another insulating pass followed by another conductive thread layer untill all of the nets were realised in this conductive non conductive alternating structure format.

 

A great prototyping idea , sadly not furthere presence in the market.

 

Went the way of other good ideas whihc presented a threat to vested interests.

Wow - I love the 3D printer...

 

NEPCON sounds like a great convention!
