Core power/DRAM power/AVDDxx power:
VRF18/VRF12/VRF12_S: •
Traces should be in inner layer or under shielding case.
VRF12_S:
Follow MMD/MES
VRF12_S should connect to VRF12 application
Trace width/length can adjust by application Imax
If trace is series 0Ω resister, 0Ω resister is having 0~50mΩ variation. It would be drop voltage.

Chip Placement Recommendation Following PCB layout are recommended by MTK for WLCSP (MT6359 / MT6315 / MT6360 / MT6680) WLCSP 請注意週邊的 IC 1. Opposite shield frame could not overlap package balls
2. The opposite chip (especially large chip, ex. AP & eMCP) could not overlap package balls 3. If underfill was adopted, the properties were recommended : - CTE-1 < 30 ppm/˚C, Tg > 125 ˚C
