  • Direct Patterning of Copper on Polyimide by Site‐Selective ...

    2011-3-22 · We demonstrate a simple route to fabricating copper circuit patterns on the surface of polyimide film. The copper pattern can be obtained in three steps: 1) Formation of partially potassium hydroxide modified pattern via a screen-printing process, 2) formation of macromolecular metal complex with copper, and 3) copper metallization by DMAB reduction.

  • An Ultimate Guide To The PCB Manufacturing Process | MCL

    The plating process uses a chemical to fuse all of the different layers of the PCB together. After being cleaned thoroughly, the PCB is bathed in a series of chemicals. Part of this bathing process coats the panel in a micron-thick layer of copper, which is deposited over the top-most layer and into the holes that have just been drilled.
