Abstract: A package structure and a method of forming the same are provided. The package structure includes a first die, a second die, a first encapsulant, and a buffer layer. The first die and the second die are disposed side by side. The first encapsulant encapsulates the first die and the second die. The second die includes a die stack encapsulated by a second encapsulant encapsulating a die stack. The buffer layer is disposed between the first encapsulant and the second encapsulant and covers at least a sidewall of the second die and disposed between the first encapsulant and the second encapsulant. The buffer layer has a Young's modulus less than a Young's modulus of the first encapsulant and a Young's modulus of the second encapsulant.

Abstract: A control apparatus for a lubrication pump to supply lubrication oil to a plurality of working machines includes a tank stored with lubrication oil therein, a cover being covered on the tank having a control panel allowing a user to preset intermittent cycle for oil supplying to external working machines via a pipe, a motor transmittedly engaged to a pump which is installed in the inner space of the tank having a plurality of oil passages allowed to transport the oil from the tank to external working machines. A pressure-adjusted valve is located in the cover exactly at one of the oil passage for adjusting the oil flow rate therethrough. A control circuit installed inside the control panel allows the user to preset the intermittent supplying cycle and indicates insufficient oil situation if the tank is short of oil.
