摘要:
A substrate for mounting a flip chip and a method of manufacturing the substrate method of manufacturing the substrate are disclosed. Using a method of manufacturing a substrate for flip chip mounting that includes providing an insulating layer, in which a circuit pattern is buried, and forming at least one bump pad shaped as an indentation by removing at least one portion of the circuit pattern, the bumps pads can be formed by removing portions of a circuit pattern in the shape of indentations, to prevent solder bumps from flowing to the insulating layer portions and reduce the pitch between bumps.

An aspect of the present invention features a method for manufacturing a substrate having a cavity. The method can comprises: (a) forming an upper layer circuit on an upper seed layer; (b) laminating a dry film on a portion of the-upper seed layer where a cavity is to be formed; (c) fabricating an upper outer layer by forming an insulation layer on top of the upper seed layer and on top and sides of the upper layer circuit; (d) stacking the upper outer layer on one side of a core layer where an internal circuit is formed; (e) removing the upper seed layer; and (f) forming the cavity by removing the dry film. The method for manufacturing a substrate with a cavity according to the present invention can reduce the total thickness of the substrate while the thickness of an insulation layer remains the same, by forming the insulation layer on sides of an external circuit.
摘要:
Provided is an apparatus and method for providing inter-piconet data communication in a wireless personal area network. The apparatus includes a piconet association unit, a superframe synchronization unit, a superframe synchronization unit, a DSPS (device synchronized power save) set creation unit, a piconet information announcement unit, a transfer data storage unit, and a data transfer unit. The piconet association unit confirms that a plurality of piconets are located on different channels, and performs a piconet association process. The superframe synchronization unit performs superframe synchronization between piconets. The DSPS set creation unit creates a DSPS set or joining an existing DSPS set. The piconet information announcement unit provides a device with information about another data-transferable piconet and devices belonging to the piconet. The transfer data storage unit receives and stores data requested to be transferred within a superframe. The data transfer unit transmits the stored data to the destination piconet.
