Abstract: A through-hole structure for a wafer level packaging includes a wafer, a RF passage penetrating through the wafer, and a through-hole structure disposed around the RF passage. The through-hole structure has three types of structure. The through hole structure includes a plurality of holes filled with metal material thereinside. On the other hand, the through hole structure can be a plurality of holes coated with a metal layer on the internal surface thereof. Alternatively, the through hole structure has both of the two above hole structure. Depending on the structure, the through hole structure performs an electric reference for preventing the RF signal from decay or interference.

Abstract: A wireless image signal transmission device includes a wireless receiving and sending unit, an image-obtaining unit, and a control unit. The image-obtaining unit is used for obtaining an image signal. The control unit is electrically connected between the wireless receiving and sending unit and the image-obtaining unit. The control unit includes an image-processing unit, a plurality of first expanding interface units, and a core unit. The core unit is electrically connected with the image-processing unit and the first expanding interface unit so that the image-processing unit processes the image data received by the first expanding interface unit and converts the processed image data into a wireless network signal. Next, the wireless receiving and sending unit transmits the wireless network signal to the application system. Thereby, it is easy to integrate the system and can be applied to a variety of application fields.

Abstract: An automatic wireless network linking method with a security configuration includes: providing an access point with a floating service set identifier and a shared key. The floating service set identifier has a prefix name. Next, a host system is provided to execute a setting and linking application to automatically scan the access point with the prefix name and obtain the floating service set identifier of the access point. Both the access point and the setting and linking application perform an operation process to generate a dynamic key. The dynamic key is converted into a wireless network encryption algorithm. Finally, the host system links to the access point to perform wireless communication, and uses the wireless network encryption algorithm to encrypt and decrypt data. Thereby, the time required for setting up the wireless network platform is reduced.
