Abstract: The disclosure provides a power management method. The power management method is applicable to an electronic device. The electronic device is electrically coupled to an adapter, and includes a system and a battery. The adapter has a feed power. The battery has a discharge power. The power management method of the disclosure includes: reading a power value of the battery; determining a state of the system; and discharging power to the system, when the system is in a power-on state and the power value is greater than a charging stopping value, by using the battery, and controlling, according to the discharge power and the feed power, the adapter to selectively supply power to the system. The disclosure further provides an electronic device using the power management method.

Abstract: A die bonding apparatus and a die bonding method are provided, which are capable of simultaneously bonding a plurality of dies from a first placement area onto a substrate disposed on a second placement area. The die bonding apparatus includes a die sucking device which is movably located above the first placement area and a second placement area. The die sucking device includes a plurality of nozzles. The nozzles can suck the dies disposed on the first placement area, and then simultaneously bond the dies onto the substrate.
