Hi All,
Right now im doing one research regarding the Conductive materials used in PCB manufaturing. In our manufaturing we are use copper as conductive materials.
I want to know is there any conductive materials used in PCB manufaturing?
I hered from my friends,now a days fiber material was used as conductive materials instead of copper.Is is true.
Can any one let me know how we can use fiber as conductive material instead of copper...
if u have any link or documents regarding these topics its help ful for my research.

Thanks in advance...

Regards
Ansari

There is conductive epoxy, which will be used to fill the via holes

you can also use silver and carbon conductive inks in your design
application is done using screen printing

I think the conductive fiber to which you are referring is carbon composition fiber. It has been demonstrated as a practical material for solid plane layers in PCB stackups. It has the advantage of better heat dissipation and lower weight than copper.

There's a document on carbon fiber in PCB that was presented at Jet Propulsion Labrartories by the manufacturer available at : https://acquisition.jpl.nasa.gov/boo/10thAnnualScienceForum/Hunter_Technology.pdf

There's also a brief article that was published by the manufacturer of the material on their website : https://www.stablcor.com/data/circuitreearticle.pdf
