Assembly Information
SOT-363 PCB Footprint
A recommended PCB pad layout
for the miniature SOT-363 (SC-70,
6 lead) package is shown in
Figure 17 (dimensions are in
inches). This layout provides
ample allowance for package
placement by automated assembly
equipment without adding
parasitics that could impair
performance.

SMT Assembly
Reliable assembly of surface
mount components is a complex
process that involves many
material, process, and equipment
factors, including: method of
heating (e.g., IR or vapor phase
reflow, wave soldering, etc.)
circuit board material, conductor
thickness and pattern, type of
solder alloy, and the thermal
conductivity and thermal mass of
components. Components with a
low mass, such as the SOT-363
package, will reach solder reflow
temperatures faster than those
with a greater mass.
HP’s SOT-363 diodes have been
qualified to the time-temperature
profile shown in Figure 18. This
profile is representative of an IR
reflow type of surface mount
assembly process.
After ramping up from room
temperature, the circuit board
with components attached to it
(held in place with solder paste)
passes through one or more
preheat zones. The preheat zones
increase the temperature of the
board and components to prevent
thermal shock and begin evaporat-
ing solvents from the solder paste.
The reflow zone briefly elevates
the temperature sufficiently to
produce a reflow of the solder.
The rates of change of tempera-
ture for the ramp-up and cool-
down zones are chosen to be low
enough to not cause deformation
of the board or damage to compo-
nents due to thermal shock. The
maximum temperature in the
reflow zone (T
MAX
) should not
exceed 235
°
C.
These parameters are typical for a
surface mount assembly process
for HP SOT-363 diodes. As a
general guideline, the circuit
board and components should be
exposed only to the minimum
temperatures and times necessary
to achieve a uniform reflow of
solder.
