13.3 SOLDERING INFORMATION
In accordance with the RoHS European directive,
all STMicroelectronics packages have been con-
verted to lead-free technology, named ECO-
PACK^TM.
■ ECOPACK^TM packages are qualified according
to the JEDEC STD-020C compliant soldering
profile.
■ Detailed information on the STMicroelectronics
ECOPACK^TM transition program is available on
www.st.com/stonline/leadfree/, with specific
technical Application notes covering the main
technical aspects related to lead-free
conversion (AN2033, AN2034, AN2035,
AN2036).
Backward and forward compatibility:
The main difference between Pb and Pb-free sol-
dering process is the temperature range.
– ECOPACK^TM LQFP, SDIP and SO packages
are fully compatible with Lead (Pb) containing
soldering process (see application note AN2034)
– LQFP, SDIP and SO Pb-packages are compati-
ble with Lead-free soldering process, neverthe-
less it's the customer's duty to verify that the Pb-
packages maximum temperature (mentioned on
the Inner box label) is compatible with their Lead-
free soldering temperature.
