7022BG Datasheet, PDF (12/116 Pages) Aavid, Thermal Division of Boyd Corporation – Channel style heat sink with folded back fins

BGA–Solder Anchor
Solder anchor attachment
Aavid's unique Solder anchor attachment method
uses two or four small Solder anchors attached to
the circuit card and a wire spring clip to securely
fasten the heat sink to the device. This method is
rugged, compact and allows for easy removal in
case of rework.
All products include a phase change pad suitable
for most IC package styles to optimize thermal
performance. Models are available with a single
or dual spring clips for additional thermal interface
pressure. Solder anchors are ordered separately.
