Change Description: Xilinx is replacing the electrically
conductive heat sink used for some of our products (package types HQ208
and HQ240) with an electrically insulated heat sink.
Reason For Change: This minor change will provide
complete electrical insulation of the heat sink on the bottom of the package.
The change is being made to the HQ208 and HQ240 only, as these packages
have their heat sinks facing down. The current HQ304 is a heat sink up
package, and does not need this enhancement. Qualification
data for these packages is attached.
Key Dates: Xilinx has evaluation quantities of
this package available today. Standard production utilizing the enhanced
package configuration will start October 15, 1997 with conversion of all
product lines expected to be complete by July, 1998. After July, 1998 Xilinx
will make the older non-insulated packages available under SCD0509 if customers
require additional time to complete qualification testing. The last time
buy (LTB) for the older package under the SCD0509 will be December, 1998
with last time ship (LTS) in March, 1999.
Traceability: All product assembled with a date
code after July, 1998 will be of the new construction, unless ordered specifically
under SCD. However, both products are form, fit and functionally equivalent,
with similar thermal dissipation capabilities (see
attached thermal coefficient data). Device marking will not change.
Products will continue to be assembled by our qualified assembly partners
in Korea (ANAM) and Japan (SEIKO).
Immediate response to this notification is not required.
For any questions regarding this PCN you may contact Xilinx via email at
"pcn@xilinx.com" or by FAX at 408-
559-1368.
