Device marking for WLCSP49

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 identify the parts throughout supply

chain operations, are not indicated below.

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. STs Quality department must be contacted prior to any decision to use these engineering

samples to run a qualification activity.
