Abstract: A semiconductor device package includes a substrate having a surface, a conductive element disposed on the surface of the substrate, and an encapsulant disposed on the surface of the substrate and covering the conductive element. The conductive element has an upper surface facing away from the substrate and exposed from the encapsulant. Further, a roughness of the upper surface of the conductive element is greater than a roughness of a side surface of the conductive element.

Abstract: A system for monitoring the battery capacitor is disclosed. The system comprises an ADC (analog to digital converter), a CPU, a ROM, a clock generator, a SMbus (smart management bus) interface. A series of RTC interrupt signals are generated by the clock generator and feeds to the CPU. When the CPU receives a RTC interrupt, the CPU runs a program in said ROM to calculate the remaining capacity of the battery and stores it into register or RAM according to the digital signal outputs from the ADC, which converts an analog signal of the battery into a digital signal. The SM bus interface then fetches the calculated results from the CPU and displays them by LED in terms of lighting, dark and flashing.
