Device marking for WLCSP81
The following figure gives an example of topside marking orientation versus ball A1 identifier
location.
The printed markings may differ depending on the supply chain.
Other optional marking or inset/upset marks, which also depend on supply chain operations,
are not indicated below.
Figure 87. Example of WLCSP81 package marking (package top view)
1. Parts marked as ES or E or accompanied by an Engineering Sample notification letter are not yet qualified
and therefore not approved for use in production. ST is not responsible for any consequences resulting
from such use. In no event will ST be liable for the customer using any of these engineering samples in
production. ST’s Quality department must be contacted prior to any decision to use these engineering
samples to run a qualification activity.
