BGA–Clip Attachment
Clip attachment
Aavid's BGS Clip heat sinks provide a mechanical
attachment alternative to tape applications
where it is desirable to attach the heat sink
directly to the device. The unique clip uses
spring pressure to ensure even contact across
the device while the end plates firmly engage
the edge of the package, locking the heat sink
in place. Each heat sink uses pre-applied thermal
grease for optimum thermal performance.
