  • Patent number: 11978720
    Abstract: A method includes attaching a die to a thermal compression bonding (TCB) head through vacuum suction, wherein the die comprises a plurality of conductive pillars, attaching a first substrate to a chuck through vacuum suction, wherein the first substrate comprises a plurality of solder bumps, contacting a first conductive pillar of the plurality of conductive pillars to a first solder bump of the plurality of solder bumps, wherein contacting the first conductive pillar to the first solder bump results in a first height between a topmost surface of the first conductive pillar and a bottommost surface of the first solder bump, and adhering the first solder bump to the first conductive pillar to form a first joint, wherein adhering the first solder bump to the first conductive pillar comprises heating the TCB head.

  • Publication number: 20240107414
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for switching a secondary cell to a primary cell. A user equipment (UE) monitors a first radio condition of the UE for beams of a primary cell and a second radio condition for beams of one or more secondary cells configured for the UE in carrier aggregation. The UE transmits a request to configure a candidate beam of at least one candidate secondary cell as a new primary cell in response to the first radio condition not satisfying a first threshold and the second radio condition for the at least one candidate secondary cell satisfying a second threshold. A base station determines to reconfigure at least one secondary cell as the new primary cell. The base station and the UE perform a handover of the UE to the new primary cell.

  • Publication number: 20240048965
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a network assistant information (NAI) message identifying a set of characteristics of a network connection. The UE may communicate with the network node using a communication configuration associated with the set of characteristics of the network connection. Numerous other aspects are described.
