NPI Services, Inc.’s PCB designers adhere to the latest design rule guidelines on all PCB layouts for optimum performance and signal integrity. Issues receiving special and professional care include:

  • Board materials
  • Layers order, line distribution, & topology
  • Impedance control (single-ended & differential)
  • Routing sequence
  • Termination
  • Cross talk avoidance
  • Shielding and decoupling
  • Signal length control and matching
  • Stud removal (backdrilling)

Both reliability and cost concerns drive PCB layout design guidelines to emphasize DFM with special attention throughout the design specification process to:

  • Reduce number of layers
  • Reduce number of vias
  • Reduce number of holes sizes and via types
  • Accurate land pattern generation
  • Parts placement and routing appropriate to the assembly and reflow methods used 
  • Ongoing cooperation with selected PCB manufacturers
  • Plan and secure PCB fabrication material supply chain
