Implementation of change:
Expected 1st Device Shipment Date: 2008/01/29
Earliest Year/Work Week of Changed Product: 0805
Change Type Description: Bond Wire Material Composition, Lead Frame Dimensions (Internal
and External)
Description of Change (From): Current TO-220 heatsink and die attach pad thickness of
1.30mm. Material composition of wire used for wire bonding process is gold (Au) wire and
copper (Cu) wire.
Description of Change (To): New TO-220 heatsink and die attach pad thickness will be
0.51mm. There is no change in heatsink and die attach pad material. Material composition of
wire used during wire bonding process will be copper (Cu). Conversion of heatsink thickness
will be done on a part by part basis starting WW05 of 2008 to prevent mixing of product with
different heat sink dimensions in shipments during the transition period.
Reason for Change : Enhancement of leadframe design to improve package mechanical
performance and support additional demand for various TO-220 products to improve our
service to customers. There is insignificant difference in product thermal performance.
Qual/REL Plan Numbers : Q20070208
Qualification :
Passed and meet the FSC rel performance requirement
