Announcement of Heat Sinks with Attachment Holes
Issue Date: 2008/10/31

Alpha has expanded its wide range of off-the-shelf products to meet with our customer's requirements.

Alpha has released new standard series heat sinks, featuring attachment holes.

The heat sinks will come with two 3.45mm diameter holes, making them compatible with our standard push pins and springs. The springs and pins are standard catalog items, allowing each heat sink to be customized for any PCB thickness and chip size. Pin and spring combinations can be selected from our online catalog, making it simple to meet with any height restriction and attachment force requirement.

This product release includes three different fin patterns, UB, LPD and Z. Each series includes two different hole orientations, relative to airflow direction. The UB and LPD based series includes six different base sizes and four different heat sink heights. The Z based series includes five different base sizes, and two different heat sink heights.

Standard hole locations are specified, allowing engineers/designers to do board layout at an early stage.
