Solderable Studs

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 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.
