- POP package on package
- the diameter of the solder ball may be in the range from 200 um to 300 um which is quite large. It is difficult to reduce the volume of the POP structure due to the large diameters of the solder ball and the large size of contact pad corresponding to the solder ball.

So, the reliability of POP structure is not good.
