4.2 Anticipated Impact on form,fit,
function, quality, reliability or
processability?
no change
5. Reason / motivation for change
5.1 Motivation LGI leadframe supplier stops its activity in China. Consequently leadframe supplier changes
from LGI (China) to MHT (Japan).
Moreover, ST Microcontrollers Division takes the opportunity of this change to improve
package robustness by inserting slots on lead frame die pad to better anchor the molding
compound into the frame.
5.2 Customer Benefit QUALITY IMPROVEMENT
6. Marking of parts / traceability of change
6.1 Description Traceability of the change is ensured by ST internal tools.
7. Timing / schedule
7.1 Date of qualification results 2016-03-18
7.2 Intended start of delivery 2016-04-18
7.3 Qualification sample available? Upon Request
