PewCB One — PCB prototyping machine
Hi y'all! I'm one of the creators of PewCB - a PCB printer that we plan to release soon. It uses a fiber laser to selectively remove material from copper-clad ceramic blanks and to make solder paste stencils directly on the board.
We've solved many of the bottlenecks in rapid PCB prototyping, making it possible to produce a prototype like the one in the video in as little as 30 minutes - from loading the Gerber files into the PewCB app to reflow soldering and flashing the finished board.
I've been using the device in my own work for the last few months, and from my own experience, the ability to prototype and iterate this quickly becomes invaluable during R&D. So many day-to-day problems turn out to be just a small prototype board away!
So, I thought you might find it interesting, and if so, I'd be glad to answer any questions you have.
