How to get your green circuit board on the silver screen
Circuit boards that go on the screen are a classic way for an electronics company to get its message across.
But now a new kind of screen-manufacturing process may help make those boards even more appealing.
The process is called “screen printing,” and the tech is starting to make a splash in the tech world.
Circuit boards are being printed on the side of a car in the U.S. and elsewhere, and even in the movie “Gravity,” the filmmakers used screen-printed circuit boards for the camera.
Some designers are even experimenting with printing on a screen in a movie theater.
The tech has also been used in some fashion to produce printed circuit boards in the past, and a new paper published this month describes the process, which can be used to make some very special circuit boards that look almost exactly like the real thing.
“We have a lot of these, and we’re using them,” said Chris Waddell, a professor at the University of Washington who studies digital printing.
“You can print circuit boards out of paper that you can’t even see through.”
This is a screen-printing process, so it doesn’t look exactly like a circuit board.
It doesn’t have the wires that you see on the circuit board in the picture.
But this new process does look a lot like a printed circuit board, Waddill said.
And the results are almost indistinguishable from a circuit boards you might see in a museum.
The biggest difference is that the screen is used to build a pattern, rather than a specific part of a circuit.
“It’s basically a paper cutout that you make in Photoshop, and it can print on a computer screen,” he said.
“It’s not like a computer chip, which is made of millions of little chips that you solder together and assemble in a way that is very specific to a particular application.”
To make a printed version, Wendell and his team used a new type of ink, which doesn’t require any heat or electricity to print out.
They also printed circuit blocks on a substrate that mimics the texture of glass, and used a process called photolithography to make it look like a real circuit board that would be displayed on the movie screen.
Waddell and co-author Jason J. Smith, a senior researcher at the Massachusetts Institute of Technology, said the process could be used in other kinds of electronics projects.
“If we could get a screen on that would look like the film, that would really get the message across,” Smith said.
For now, the process is being used for a very limited number of circuit boards, mostly to make the screens of cars, but the technology could eventually be used for more complex circuits.
“The thing that’s really exciting is the ability to make these things look just like the movies, and then the fact that we can print them on the surface of glass,” Smith added.
“That’s really cool.
That’s really interesting.”
