    $0.00

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

    DFM 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:
