Heat sinks ordered with solderable mounting
tabs have tin-plated spring steel tabs perma-
nently locked onto the heat sink to provide
wave solderability. The solderable tabs are
mounted on the heat sink after anodizing,
thus eliminating any special coating or han-
dling. The result is a wave solderable heat
sink with black anodized performance.

Notes: Mounting tabs have unique locking features built into their design. Aavid Thermalloy adds
to standard and custom heat sinks. For this reason, the tabs are factory applied, and cannot be sold
separately. Please see page 85 for additional tab options.
