Board Mounted Power Supplies (BMPS) Guideline I

Idea/Definition Information
Background: 

The cooperation shall consist of the following items:
 
•PSMA and EPSMA would support the “General Purpose Lead-free Assembly System” concept. It is understood that several details of the assembly system remains to be defined
 
•HDP User Group would take lead-free technology issues presented by PSMA and EPSMA into account when defining the “General Purpose Lead-free Assembly System”
 
HDP User Group has investigated the interest by its system integrator members of forming a "Requirement Reference Group” enabling PSMA and EPSMA member companies to design their products to the needs of potential customers. - The answer was YES.

 

Problem: 

 

System integrators want to have:
 
•Well defined lead-free requirements on Board Mounted Power Supplies
 
•Pin compatibility between functionally compliant Board Mounted Power Supplies
 
•Industry standards for function compatibility of Board Mounted Power Supplies
 

No requirements for modules to be attached using e.g. “press fit technology” or manual soldering

 

 

•System Integrators and Power Module Suppliers need a common communication vehicle
 
•The ”BMPS Application Guideline” is suggested to serve as a common database
 
•The guideline is on the ”base technology level”. Information from consortia such as POLA and DOSA is on the next level up when it comes to complexity

 

Approach: 

 

The BMPS Reference Group performed the Following functions:
 
•Channel the HDP User Group lead-free requirements of the “General Purpose Lead-free Assembly System” to the PSMA and EPSMA power supply organizations
 
•Review solutions presented by the PSMA and EPSMA organizations
 
Processed any other technical issue regarding BMPS issues of mutual interest
 
•Survey of the needs of system integrators and EMS providers
 
•Definition of the ”BMPS Application Guideline” concept
 
•Formation of a ”BMPS Guideline Editorial Team”
 
•Access to a technical power system technical database from Ericsson Power Modules
 
•The Core Editorial Team has assembled a comprehensive first draft ”BMPS Application Guideline” (The document had 140 pages!)
