bandwidth mode.
RECOMMENDED SOLDER PROFILES
Solder Profile for Sn/Pb Soldering
Lead (Pb)-free, Recommended Solder Profile
The TFBS6711 is a lead (Pb)-free transceiver and qualified
for lead (Pb)-free processing. For lead (Pb)-free solder paste
like Sn
profiles: Ramp-Soak-Spike (RSS) and Ramp-To-Spike
(RTS). The Ramp-Soak-Spike profile was developed
primarily for reflow ovens heated by infrared radiation. With
widespread use of forced convection reflow ovens the
Ramp-To-Spike profile is used increasingly. Shown in
figure 5 and 6 are Vishay’s recommended profiles for use
with the TFBS6711 transceivers. For more details please
refer to the application note “SMD Assembly Instructions”.
Wave Soldering
For TFDUxxxx and TFBSxxxx transceiver devices wave
soldering is not recommended.

Manual Soldering
Manual soldering is the standard method for lab use.
However,
recommended because the risk of damage is highly
dependent on the experience of the operator. Nevertheless,
we added a chapter to the above mentioned application note,
describing manual soldering and desoldering.
Storage
The storage and drying processes for all Vishay transceivers
(TFDUxxxx and TFBSxxx) are equivalent to MSL4.
The data for the drying procedure is given on labels on the
packing and also in the application note “Taping, Labeling,
Storage and Packing”.
