ELLIPTICAL FIN HEAT SINK
900 Series
Wakefield-Vette’s heat sink assembles onto chip set using the space that is between the PCB and
the substrate of the solder balls. The solder balls provide a minimal gap of .5mm to .7mm.
Attachment feature is below a .4mm thickness. The clipping system will not interfere or damage
chip. Contact area is the edge of chip.
ASSEMBLY INSTRUCTION:
Step 1:
Hook the
clip under one
side of the BGA
chip set.
Step 2:
Rotate
assembly down
until opposite
side clip engages
substrate edge of
BGA chip set.
Step 3:
Make sure
the sop rods are
clearing from edges
of BGA chip set.
Step 4:
Press firmly
down to make sure
clips fully engage
edges of chip set.
Heat Sink should not
move around easily.
