  • Patent number: 12293502
    Abstract: A method for detecting defects in products from images thereof and an electronic device applying the method inputs a defect image repair data set into an autoencoder to train the autoencoder, and generates a reconstructed image, calculates a reference error value between the sample image and the reconstructed image by a preset error function, and set a threshold value based on the reference error value. The electronic device inputs an image possibly revealing a defect into the autoencoder and generates the reconstructed image corresponding to the image to be detected, and uses the preset error function to calculate the reconstruction error between the image and the reconstructed image, thereby determining whether the image being analyzed does reveal defects. When the reconstruction error is greater than the threshold value, a determination is made that a defect is revealed.

  • Publication number: 20250125292
    Abstract: A side-wettable package with edge-recessed bond pads has a composite substrate, and the composite substrate is covered with a molding layer. An upper redistribution layer is formed on the molding layer, and the upper redistribution layer is covered with a solder mask and part of the upper redistribution is exposed to form at least one surface bond pad. Surfaces of each surface bond pad are formed with an anti-oxidation conductive layer, wherein at least one side surface of each surface bond pad is recessed relative to side surfaces of the molding layer. The present invention does not form the side-wettable structure by cutting the upper redistribution layer to prolong service life of cutting Wheels and structural stability of the package. The anti-oxidation conductive layer increases a contacting area between solder and each surface bond pad, thereby facilitating AOI instruments to determine soldering condition of the package and another component.

  • Publication number: 20250024523
    Abstract: The disclosure describes techniques for configuring wireless routers of a wireless mesh network with one or more secondary wireless access points (WAPs) such that client devices connected to the mesh network may remain online in the event that a primary WAP goes offline or otherwise becomes unavailable. For instance, a user of the wireless mesh network may specify a device, such as a mobile electronic device connected to a cellular network, to operate as a secondary WAP in the event that a primary WAP becomes unavailable. Thereafter, upon a wireless router of the mesh network detecting that the primary WAP is unavailable, the wireless router may perform a network scan to identify SSID(s) that are available within the environment. The wireless router may also instruct the other routers of the mesh network to perform a network scan.
