Studs
Solderable Studs
Threaded solderable studs are permanently swaged in place
for quick pre-assembly with the transistor. The device is
placed over the stud (s) followed by the lock washer and
nut. This entire component is then dropped into plated-thru
holes in the printed circuit board for wave soldering. The
end of the stud is tin-plated for excellent solderability and
extends only 0.040" below a 0.062" PC board to clear lead
trimming saws.

Device Mounting Studs
Device mounting studs for "Thermalloy-origin"
items are available as options on certain vertical
and board mount heat sinks as a labor-saving aid
for mounting semiconductors. This optional feature
speeds production assembly time and reduces
hardware requirements.
