BGA–Push Pin Attachment
Push pin attachment
Push pin heat sinks require two 3.10mm holes in the circuit card
to quickly attach the heat sink over the device. The one piece
design makes assembly a snap. Pressure is maintained by the
tension of the push pin coil springs to ensure even pressure
across the device. Push pins provide a greater margin of reliabil-
ity in applications where gravity or vibration may cause tapes or
adhesives to fail. The addition of a phase change pad optimizes
thermal performance.
