Solderable Pins
Solderable Nuts
ORDERING INFORMATION
Vertically mounted, extruded heat sinks are
converted to wave solderable with the addition
of solderable roll pins. Roll pins are available
with stand-off shoulders in different heights
for easier cleaning after wave soldering.
ORDERING INFORMATION
Suffix
P2
P3
N/A
Solderable nuts are permanently swaged into the heat sink
for quick pre-assembly with the transistor. Screws are used
to mount to the heat sink and are installed from the top.
Solderable nuts feature a closed end that prevents solder
from wicking into threads and trapping contaminants or flux.
Heat sink and transistor are then handled as a single compo-
nent and dropped into plated-thru holes in the PC board for
wave soldering. (Solderable nuts require slightly larger printed
circuit board hole sizes)
Suffix
SNM-1
SNE-1
SNE-2
Note: If a part number requires 2 solderable nuts, simply add a "/2" after the solderable
nut character suffix on Thermalloy origin parts.
