Module-to-PWB Interconnections

Idea/Definition Information
Actual Project Stage: 
Idea and Definition
Project Category: 
Power Supply
Project Leader Company: 
Juniper
Background: 

System integrators want to have well defined Lead Free requirements on Board Mount Power Supply (BMPS), Pin compatibility between functionally compliant BMPS, and industry standards for function compatibility of BMPS.  They also want to eliminate the need for modules to be attached using "press fit technology" or manual soldering.

Problem: 

Systems Integrators and Power Module Suppliers need a common communication vehicle that will define options for pin and function compatibility, reliable interconnection techniques, and "best practices" for design, manufacturing, and assembly of BMPS.  The objective of the project is to:

  • Identify the key design/manufacturability issues with a focus on assembly
  • Issue guidelines on PWB layout for BMPS that will aid in assembly
    • Pad configurations, etc.
  • Issue guidelines for automated handling of BMPS
    • Pick and place nozzles, grippers, etc.
  • Demonstrate the feasibility/applicability (and reliability) of module - PWB interconnections
Approach: 

The project team shall establish requirements and issues raised by the customers, i.e. system integrators and EMS providers

  1. Examine and evaluate available solutions
  2. Suggest a test vehicle and design of experiments
  3. Generate engineering information
  4. Issue guidelines and integrate with BMPS report
