Bridging the gap between design and production with DFM PCB verification

Siemens Valor NPI

Valor NPI for the PCB Design For Manufacturing is Siemens' tool that brings real-world knowledge of manufacturing processes directly into the PCB design flow

This tool allows you to perform DFM analysis at any time by being able to find any manufacturability problems and solve them quickly, facilitating release to production.
Why choose Valor NPI for PCB Design for Manufacturing (DFM PCB)?

DFM PCB driven by the production process

With Valor NPI, Design for Manufacturing is fully integrated into the design flow, using information that belongs both to the design itself and to the different stages of production (manufacturing and assembly). PCB classification factors drive PCB classification, which drives manufacturing constraints based on software that knows the applicable manufacturing processes.

PCB Classification Factors

Factors are features of the PCB design that can be used to determine board types, refine constraint rules, and determine which DFM controls should be performed. From the EDA data, it is possible to derive information such as:

  • Types of layer
  • Spacing intervention
  • Leader width intervention.
  • Copper weight
  • Number of layers

PCB classification

Different types of boards with different manufacturing processes require different DFM rules. So PCB Design can be classified, for example, by:

  • Process definitions
  • Technological levels such as standard, advanced and microelectronics
  • SMT on one side,
  • SMT on two sides
  • Ground systems, airborne systems.
  • IPC Class 1, 2 or 3
  • Board features such as typical line width
PCB Manufacturing Constraints

The constraints are based on the capacity of production and on the factors of design. Here, we need to know what the limits of their manufacturing partners' capabilities are for the required processes.

For example:

  • Copper Spacing
  • Annular Ring
  • Plane Spacing
  • Solder Mask Coverage
  • Silk Screen Spacing
  • Solder Volume
  • Component Spacing
  • Component Shadowing
  • Test Access
