Device marking for WLCSP49

The following figure gives an example of topside marking versus ball A 1 position identifier

location.

The printed markings may differ depending on the supply chain.

Other optional marking or inset/upset marks, which depend on supply chain operations, are

not indicated below.

Figure 36. WLCSP49 marking example (package top view)

1. Parts marked as “ES”, “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.
