Figure 16.

WLCSP8 – Wafer level chip scale package outline

Drawing is not to scale and corresponds to preliminary data.

The dimension is measured at the maximum bump diameter parallel to primary datum Z.

The primary datum Z and seating plane are defined by the spherical crowns of the bump.

Bump position designation per JESD 95-1, SPP-010.
