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.
