https://devzone.nordicsemi.com/f/nordic-q-a/59421/the-tolerance-of-dimension-d-e-min-max-of-52840-wlcspHi Sir, In the datasheet (V1.1), the table-145 shows the dimensions of WLCSP, but there is no tolerance of D/E/D2/E2 Could you help to advice what is the tolerance of dimension D, E, D2, E2 (min/max) of 52840-CKAA (WLCSP)? Thank you.
