HOW WILL THE CHANGE BE QUALIFIED?
Qualification is being done according to STMicroelectronics Corporate procedure.
IMPACT ESTIMATION AT USER'S SIDE
These changes should have no impact because the plating technologies used are compatible with both
Leaded and Lead-free assembly processes.
ABOUT TRACEABILITY
The Lead-free parts can be identified in three ways: The letter E (as in ECOPACK
®
) will appear in the
brand. Furthermore, the trace code can be used to determine the time and place of manufacture, and
hence the material content. Finally, the Lead-free parts will be labeled in a new format as shown in Figure
1, Figure 2, and Figure 3.
The full trace code per ST's new standard will be shown on the end of the inner bulk box (i.e. box inside
shipping carton) as shown in Figure 3.
Figure 1. Lead-free Devices in the CAPHAT™ Package
The Lead-free parts will be labeled with the following format:
Note: 1. The last two rows comprise the trace code, formatted as in Figure 2 and Figure 3, page 2.
2. The rotated text on the right (“BBBBB”) is the battery trace code.
Figure 2. Assembly Site Trace Code (Row 5)
Figure 3. Country of Origin Trace Code (Row 6)
■ The first row includes the ST logo and the Underwriter’s Laboratories logo.
At the lower right corner of the ST logo is the letter “E” (as in ECOPACK).
Lead-free parts can be identified by the letter “E.”
■ The second row of text is the salestype (part number).
■ The third row is the device family.
(1)
■ The fourth row identifies it as having a battery.
