摘要： A chip scale package implements solder bars to form a connection between a chip and a trace, formed in a substrate, such as another chip or PCB. Solder bars are formed by depositing one or more solder layers into the socket, or optionally, depositing a base metal layer into the socket and applying the solder layer to the base metal layer. The geometry of a solder bars may be rectangular, square, or other regular or irregular geometry. Solder bars provide a greater utilization of the connectivity footprint and increase the electrical and thermal flow capacity. Solder bars also provide a robust connection.

摘要： A multi-phase, coupled-inductor, DC-DC voltage converter operates in discontinuous conduction mode (DCM) when the system is operated at low output power demand. An embodiment of the converter switches to operating in continuous conduction mode (CCM) when the system is operated at high output power demand.
