question Printing PCB circuitboards Homemade

Dear Support, I was wondering and trying to find out where to put this on the E2E forum, on new developments besides IC chips,

so bear with me. Is there a department in Texas Instruments, that is interested in Printing Circuitboards with liquids?

I stumbled on a alternative to milling circuitboards. by using a device that is called the DMP2800( 25um Resolution, and depending on the conductive Ink (copper or silver based you can create even smaller traces).

The Idea I had was the following which I would like to share:

order a thin layer of plastic maybe Teflon or just FR4 around 50um with copper both sides, use some dynamask,
UV cure that then put it under the DMP2800(smallest resolution, 25um) (UV cure the Ink, or heat cure it) then add another layer of dynamask.
heat cure this again and voila, you get the thinnest substrate, (especially good for HF, and the traces are thinner then regular cnc Mill which is 0.1mm).

here are a few companies that offer inks, that are UV or Heat Curable.

Silver conductive liquid from MG chemicals is 0.2Ohm per inch.

I am greatly looking forward to your replies!

  • Hello Bastiaan, 

      Thank you for providing this information.  There may be some Product Groups that could be interested in this pcb technology, although I am not aware of any actively pursuing this technology.  Again, thank you for the information.  

      Have you designed a pcb with this technology, using TI devices in that design?  

    Regards,
