印刷电路板设计的最佳实践 Best PracTIces in Printed Circuit Board Design

The manner in which electronics as consumer devices and industrial machinery has become an integral part of our daily lives needs little introducTIon or descripTIon. From complex machinery in factories, to computers, engineers have transiTIoned their ideas to conception of such devices through various technology including small rugged, inexpensive and reliable printed circuit boards (PCBs).

The design engineer faces a number of hurdles in the design of such devices, most notably the fact that traditionally each stage in their design flow is segregated, between part-selection, design, and validation.

National Instruments provides a complete PCB design platform with the ease-of-use and power of NI Multisim capture and simulation, and the integrated NI Ultiboard layout and routing environment. Built upon a platform which simplifies the board-level simulation process with intuitive SPICE analyses and an expandable measurement interface, the complete PCB solution from NI also provides the unique capability of integrating the PCB design flow with real measurements.

As we will explore through this article, it is the unification between design and measurements (a concept known as integrated design and test) which provides the basis of for better addressing the hurdles in the design, verification and production of printed circuit boards.

This article is an overview of the design flow and the Best Practices in using the features of NI Multisim, NI Ultiboard and NI LabVIEW to transition from schematic, simulation, layout to manufacturing.
