DesignTrue DFM

What is DesignTrue DFM?

Design for Manufacturability (DFM) is the process of designing a PCB in a way that ensures it can be manufactured reliably, efficiently, and at a lower cost. DFM involves assessing and optimizing various aspects of the design to reduce production issues, improve yield, and minimize the need for rework or adjustments during manufacturing. This approach is essential in PCB design to ensure that designs transition smoothly from concept to production. DFM can be implemented by defining and assigning rules that ensure proper fabrication (DFF), assembly (DFA), and testing (DFT).

Benefits

  • Increase PCB Manufacturability
  • Reduce Manufacturing Costs
  • Minimize Errors and Delays

DesignTrue DFM in OrCAD X

DesignTrue DFM provides a wizard-based approach to creating and assigning rules for fabrication, assembly, and testing based on IPC and common fabrication standards. DesignTrue DFM saves time with an automatic approach to DFM rule creation and assignment and can be configured based on manufacturer’s specifications to minimize production delays.
  • Pre-defined rules from popular suppliers in the DFM Partner Portal
  • Incorporation of Stackup Information
  • Rigid and Flex stackup support
  • CSV file import for rule definition
  • Automatic creation of DFF, DFA, and DFT constraints and constraint sets
  • Automatic assignment of rules in the design
  • Automatic Design Rule Check after Rule Implementation

Key Features of Design True DFM in OrCAD X and Allegro X

OrCAD X contains the functionality you need to ensure manufacturability for your PCB designs.
DFM Wizard
A wizard-based approach to design for manufacturing rules allows designers to import manufacturer specifications quickly. The DFM wizard will automatically create and assign the required to fabricate and assemble your PCBs saving your designers time.
DFM Partner Portal
The DFM Partner Portal contains the specifications required to fabricate and assembly your PCBs from the leading manufacturer’s helping designers validate manufacturability and shorten production cycles. Easily import these specifications directly into your Cadence software to find, fix, and avoid manufacturing errors.
Fabrication Rules
Easily define and assign the rules required to fabricate your PCB designs accurately and efficiently with support and checks for annular ring, copper features including antennas and acid traps, copper spacing, silkscreen, spacing to outlines and cutouts, mask slivers and mask islands.
Assembly Rules
Ensure that your PCB can be assembled by your manufacturer by defining the required rules including proper spacing to design outlines, package to package spacing, component spacing, and pastemask checks.
Testing Rules
Guarantee the testability of your PCB designs with rule support for common DFT issues including test point spacing to cutouts and outlines, identifying test points on soldermask and silkscreen, identifying test points under components and defining the minimum test point pad size for successful probe measurements.
DFM Rule Reuse
Easily import and export rules or constraints to save time with design setup and ensure manufacturability for future designs. Create different technology files for manufacturers to quickly adhere to the specifications for your varying fabrication houses.
