11. DESIGN FOR EXCELLENCE (DFX)
11.1. TESTABILITY
The WM-BG-MR-01 module can be tested on the by using adapter card or similar interface.
The adapter card must be such that from the FTS the WM-BG-MR -01 module is seen and
recognized as PC Card or Compaq Flash.
Ÿ No additional test pins are required to support in-circuit testing.
11.2. LOGISTICS
All customer specific requirements – customization – will be implemented at the highest
possible level to support build to order and keep the number of modules in SMT to a minimum.
Additional module variants might be added base on business potential.
