Ordering code
The shape and hole pattern of the heat sink will determine the shape and hole
pattern of the pad. If you are ordering a heat sink which mounts to a semicon-
ductor on both sides, the ordering code for two pads should be used. To order
additional Hi-Flow? pads separate, or factory applied variations please contact
an Aavid sales rep for inquiries.

Alignment Pads
Solderable alignment pads are an innovative
way to attach the heat sink to your transistor that
could cut your assembly time by more than half.
Alignment pads provide cost effective solderability,
while providing numerous additional benefits.
Alignment pads are factory applied and can be
bought separately as well. Please refer to accessory
