  • Publication number: 20240314674
    Abstract: A wireless communication method employed by an access point (AP) includes: negotiating with another AP for setting up a coordinated service period (SP), and sending a first announcement frame inside a first basic service set (BSS) to inform that the coordinated SP has been created. The step of negotiating with the another AP for setting up the coordinated SP includes: receiving a request frame from the another AP, wherein the request frame includes a plurality of SP parameters; and sending a response frame to the another AP. The AP belongs to the first BSS, and the another AP belongs to a second BSS different from the first BSS.

  • Patent number: 12089134
    Abstract: An access point (AP) includes a transmitter (TX) circuit, a receiver (RX) circuit, and a control circuit. The control circuit negotiates with at least one another AP via the TX circuit and the RX circuit, for setting up a coordinated service period (SP). In addition, a method for setting up the coordinated SP in a multiple AP environment includes: sending a request frame from a first AP to at least one second AP, wherein the request frame includes a plurality of SP parameters; receiving a response frame generated from the at least one second AP in response to the request frame; and in response to the response frame, setting up the coordinated SP by sending a setup frame to the at least one another AP, wherein the setup frame is set by updating at least a portion of the plurality of SP parameters.

  • Publication number: 20240120241
    Abstract: The present invention provides an electrostatic charge detecting packaging device comprising a carrier, multiple dies, and multiple electrostatic-charge-sensitive components; the carrier has a surface; the dies are mounted on the surface of the carrier; and the electrostatic-charge-sensitive components are mounted on the surface of the carrier; since an electrostatic voltage tolerance of each of the electrostatic-charge-sensitive components is lower than an electrostatic voltage tolerance of each of the dies, accumulated electrostatic charges are more likely to discharge towards the electrostatic-charge-sensitive components than towards the dies, and as such, by electrically testing whether the electrostatic-charge-sensitive components are functioning normally when packaging the dies, the present invention allows personnel to debug for knowing which packaging steps exactly cause more serious problems that lead to damaging electrostatic discharges in the dies.

  • Publication number: 20230395465
    Abstract: A semiconductor package with improved solderability at sidewall includes a chip, a molding compound encapsulating the chip, and multiple leads distributed at sidewalls of the semiconductor package. The leads are formed as a conductive layer that is electrically connected to bonding pads of the chip. Each of the leads has a stepped surface exposed from the molding compound, wherein the stepped surface is shaped by two sequentially overlapped photoresist layers. The stepped surface of each lead allows to accommodate more solder to enhance the reliability of a solder joint between the semiconductor and a printed circuit board. Therefore, the solder joints of the semiconductor package are easily inspected by automatic optical inspection (AOI) equipment.

    Abstract: The present invention includes a chip, a plastic film layer, and an electroplated layer. A front side and a back side of the chip each comprises a signal contact. The plastic film layer covers the chip and includes a first via and a second via. The first via is formed adjacent to the chip, and the second via is formed extending to the signal contact of the front side. A conductive layer is added in the first and the second via. The conductive layer in the second via is electrically connected to the signal contact of the front side. Through the electroplated layer, the signal contact on the back side is electrically connected to the conductive layer in the first via. The conductive layer protrudes from the plastic film layer as conductive terminals. The present invention achieves electrical connection of the chip without using expensive die bonding materials.
