  1. PCB Layout Example

    DFM&R100, Design for Manufacturability & Reliability - 100% coverage

    Save 3-5 weeks Time-to-Market and likely one fab spin. - ROI is usually 5-10x of DFM&R cost.

    DFM&R Service (Design for Manufacturability & Reliability) using Valor NPI:

         - 100 percent component coverage.  Any components not on file in the Valor library
           (30+ million components) are created and checked.  Customer is contacted 
           within 24-48 hrs for any missing datasheet information (component mechanical dimensions) 
         - Standard turn: 48-72 hours.  For expedited turn (24-48 hrs, increased fee of 50%)
         - We generally find at least one item which will require redesign of the fab/PCB
           and/or change in the BOM (Bill of Materials)§Comprehensive set of DFM rules
         - Report outlines violations, exact location, and recommended fix / solution
         - Provide recommended footprint which reduce assembly rework and enhances long term reliability of solder joints
         - Over 520 checks performed, comprehensive set of DFM rules, plus netlist and BOM validation
         - Require excel BOM which includes Manufactuer Part Number plus reference designator
         - Require CAD Data.  Accepted formats listed in order of preference:
                            Design Software / format                            File extension
                                   ODB++                                                TGZ, .TAR, .XML.GZ

  2. PCB Layout Example

    DFM&R75, Design for Manufacturability & Reliability (~75 to 85% coverage)

    Save 3-5 weeks Time-to-Market and likely one fab spin. - ROI is usually 5-10x of DFM cost.

    DFM&R Service (Design for Manufacturability & Reliability) using Valor NPI:

         - approximately 65-85 percent component coverage.  Any components not on file in the Valor library
           (30+ million components) are not checked for expediancy
         - Standard turn: 24-48 hours
         - Report outlines components not included in the library/check
         - Report outlines violations, exact location, and recommended fix / solution
         - Over 520 checks performed, comprehensive set of DFM rules, plus netlist and BOM validation
         - Provides recommended footprints which reduce assembly rework and enhances long term reliabilitity of solder joints
         - Requires excel BOM which includes Manufactuer Part Number plus reference designator
