NPI’s PCB CAD designers have a wealth of experience in PCB layout design with technological expertise that includes High Speed Digital, RF, Analog, Mixed Signals, Backplanes, Flex Circuits, and Power Supplies. PCB layout design can be achieved through multiple CAD and PCB layout software platforms that include Cadence Allegro, Mentor Expedition, and Altium Designer.

NPI’s utmost concern is PCB Design for Manufacturability (DFM). As such, NPI’s PCB CAD service ownership includes ensuring that all PCB design parameters match the capabilities and recommendations of the chosen PCB manufacturer to ensure successful high quality manufacture of your quick turn PCB prototype or product.
