Solderable Nuts
FEATURES
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)
