Recommended Solder Profiles
Solder Profile for Sn/Pb Soldering
Lead (Pb)-Free, Recommended Solder Profile
The TFDU4100 is a lead (Pb)-free transceiver and
qualified for lead (Pb)-free processing. For lead (Pb)-
free solder paste like Sn (3.0 - 4.0) Ag (0.5 - 0.9) Cu,
there are two standard reflow 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 below in fig-
ure 6 and 7 are VISHAY's recommended profiles for
use with the TFDU4100 transceivers. For more
details please refer to the application note
“SMD Assembly Instructions”
(http://www.vishay.com/docs/82602/82602.pdf).
A ramp-up rate less than 0.9 °C/s is not recom-
mended. Ramp-up rates faster than 1.3 °C/s could
damage an optical part because the thermal conduc-
tivity is less than compared to a standard IC.
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, for a production process it cannot be rec-
ommended because the risk of damage is quite highly
depending on the experience of the operator. Never-
theless, 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 equiva-
lent 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"
(http://www.vishay.com/docs/82601/82601.pdf).
