Soldering Information - Surface mounting
The surface mount version of the product is intended for
convection or vapor phase reflow Pb-free processes. To
achieve a good and reliable soldering result, make sure to
follow the recommendations from the solder paste supplier,
to use state-of-the-art reflow equipment and reflow profiling
techniques as well as the following guidelines.
A no-clean flux is recommended to avoid entrapment of
cleaning fluids in cavities inside of the DC/DC regulator. The
cleaning residues may affect long time reliability and isolation
voltage.
Minimum pin temperature recommendations
Pin number 9 is chosen as reference location for the minimum
pin temperature recommendations since this will be the
coolest solder joint during the reflow process.
SnPb solder processes
For Pb solder processes, a pin temperature (T
PIN) in excess of
the solder melting temperature, (T
L, +183 °C for Sn63/Pb37)
for more than 30 seconds, and a peak temperature of
+210 °C is recommended to ensure a reliable solder joint.
Lead-free (Pb-free) solder processes
For Pb-free solder processes, a pin temperature (T
PIN) in
excess of the solder melting temperature (T
L, +217 to +221 °C
for Sn/Ag/Cu solder alloys) for more than 30 seconds, and a
peak temperature of +235 °C on all solder joints is
recommended to ensure a reliable solder joint.
Maximum regulator temperature requirements
To avoid damage or performance degradation of the product,
the reflow profile should be optimized to avoid excessive
heating. The maximum product temperature shall be
monitored by attaching a thermocoupler to the top of the
main transformer.
A sufficiently extended preheat time is recommended to
ensure an even temperature across the host PCB, for both
small and large devices. To reduce the risk of excessive
heating is also recommended to reduce the time in the reflow
zone as much as possible.
SnPb solder processes(PENDING)
For conventional SnPb solder processes, the product is
qualified for MSL 1 according to IPC/JEDEC standard
J-STD-020C.
During reflow, T
P must not exceed +225 °C at any time.
Lead-free (Pb-free) solder processes
For Pb-free solder processes, the product is qualified for
MSL 3 according to IPC/JEDEC standard J-STD-020C.
During reflow, T
P must not exceed +260 °C at any time.
