A BGA structure having larger solder balls in high stress regions of the array is disclosed. The larger solder balls have higher solder joint reliability (SJR) and as such may be designated critical to function (CTF), whereby the larger solder balls in high stress regions carry input/output signals between a circuit board and a package mounted thereon. The larger solder balls are accommodated by recessing each ball in the package substrate, the circuit board, or both the package substrate and the circuit board. Additionally, a ball attach method for mounting a plurality of solder balls having different average diameters is disclosed.

Generation of filtering rules for incoming messages can be activated by a user through a gesture-based input. When the user activates filtering rule generation, the message management service can cause a user device to display a prompt requesting additional data to be used to generate the filtering rule. The gesture can be a swipe and hold gesture, where the swipe is associated with an action (archiving, deleting, deferring, or adding the message to a list), and the swipe and hold action can activate filtering rule generation associated with the action.

A method for forming a silicon carbide module integrated structure includes a heat sink and a silicon carbide module, which is fixedly connected with the heat sink. The solder paste is arranged between the heat sink and the silicon carbide module, and the heat sink and the silicon carbide module are hot pressed through a welding process to weld the silicon carbide module and the heat sink together.

A substrate working machine including: a conveyance device configured to convey a substrate; a holding device configured to hold the substrate conveyed to a work position by the conveyance device; and a control device configured to control operation of the conveyance device, wherein the control device is configured to control the operation of the conveyance device such that the substrate is conveyed at a conveyance speed calculated based on a preset setting time and a conveyance distance of the substrate from the work position by the conveyance device or a conveyance distance of the substrate to the work position by the conveyance device.

A process for batch fabrication of circuit components is disclosed via simultaneously packaging multiple circuit component dice in a matrix. Each die has electrodes on its tops and bottom surfaces to be electrically connected to a corresponding electrical terminal of the circuit component it's packaged in. For each circuit component in the matrix, the process forms preparative electrical terminals on a copper substrate. Component dice are pick-and-placed onto the copper substrate with their bottom electrodes landing on corresponding preparative electrical terminal. Horizontal conductor plates are then placed horizontally on top of the circuit component dice, with bottom surface at one end of each plate landing on the dice's top electrode. An opening is formed at the opposite end and has vertical conductive surfaces. A vertical conductor block is placed into the opening and lands on the preparative electrical terminal, and the opening's vertical conductive surfaces facing the top end side surface of the vertical block. A thermal reflow then simultaneously melts pre-applied soldering material so that each circuit component die and its vertical conductor block are soldered to the copper substrate below and its horizontal conductor plate above.
