Polymer ink is used to create the layers of the build whereas silver polymer is used for creating the traces and holes used to permit electricity to move. Current circuit board manufacturing often a|could be a} tedious process relying on the design. Specified supplies are gathered and sent into internal layer processing where photographs are printed, developed and etched. The etches cores are sometimes punched to add lamination tooling. The stack-up, the buildup of a circuit board, is built and sent into CNC machining lamination where the layers are bonded.
