CAUTION
SSSS Hand assembly
If PC boards are assembled by hand, care must be taken
to avoid mechanical damage. We recommend:
- Use tweezers, the components should be gripped
across the two terminals, A.
- Avoid any contact with the cut surface, C.
- The usage of a pen under vacuum on the surface B
is recommended.

SSSS Soldering iron
In case of hand soldering the following recommandations
must be taken:
- Maximum temperature:
250_C on the soldering
iron.
- Soldering time:
5 s max.
- Avoid contact between the iron soldering and chip.
SSSS Soldering and flux recommendation
- Solder:
SnPb solder paste
- Flux:
no-clean flux.
SSSS Cleaning
To clean flux from the PC board assembly, use a suitable
solvent such as Isopropylalcohol.
Solvents such as Toluene, Xylene and Trichloroethylene
should be avoided.
