  • Publication number: 20240128216
    Abstract: A bonding structure that may be used to form 3D-IC devices is formed using first oblong bonding pads on a first substrate and second oblong bonding pads one a second substrate. The first and second oblong bonding pads are laid crosswise, and the bond is formed. Viewed in a first cross-section, the first bonding pad is wider than the second bonding pad. Viewed in a second cross-section at a right angle to the first, the second bonding pad is wider than the first bonding pad. Making the bonding pads oblong and angling them relative to one another reduces variations in bonding area due to shifts in alignment between the first substrate and the second substrate. The oblong shape in a suitable orientation may also be used to reduce capacitive coupling between one of the bonding pads and nearby wires.

  • Publication number: 20150176737
    Abstract: A block ring for a tube assembly for a reverse osmosis filter cartridge has multiple block segments connected to each other into a loop; any two adjacent ones of the block segments pivotally connected to each other, and outer ends of two of the block segments detachably abutting each other. For assembling, the block ring that is not formed into a loop yet is mounted into an outer annular groove of a tube body, and then the two block segments are rotated to make the outer ends abut each other. Thus, the block segments are braced transversely to securely abut the outer annular groove. Therefore, the block ring is securely mounted in the tube body. Besides, the block ring is integrated axially, such that the block ring can effectively and axially bear the outward abutting of a bearing plate, which prevents the block ring from deformation and enhances the safety.
