  • Patent number: 11355429
    Abstract: An electrical interconnect structure includes a bond pad having a substantially planar bonding surface, and a solder enhancing structure that is disposed on the bonding surface and includes a plurality of raised spokes that are each elevated from the bonding surface. Each of the raised spokes has a lower wettability relative to a liquefied solder material than the bonding surface. Each of the raised spokes extend radially outward from a center of the solder enhancing structure.

  • Patent number: 8975117
    Abstract: A method includes providing a semiconductor chip having a first main surface and a second main surface. A semiconductor chip is placed on a carrier with the first main surface of the semiconductor chip facing the carrier. A first layer of solder material is provided between the first main surface and the carrier. A contact clip including a first contact area is placed on the semiconductor chip with the first contact area facing the second main surface of the semiconductor chip. A second layer of solder material is provided between the first contact area and the second main surface. Thereafter, heat is applied to the first and second layers of solder material to form diffusion solder bonds between the carrier, the semiconductor chip and the contact clip.

  • Publication number: 20060042045
    Abstract: The handle of wheelbarrow is commonly produced separately before they are welded together to form the entire handle. The process involves more steps and equipment, which has increased the producing cost relatively. The present invention provides a simpler process to fabricate the handle, where the narrow portion at the end portion part of the handle is integrally formed with the body portion of the handle for a wheelbarrow.

  • Publication number: 20060033311
    Abstract: The present invention is an improved wheelbarrow with a releasable container connected to a releasable locking system for easy pouring and requiring small leverage to lift the container. The improved wheelbarrow comprising a lever mounted directly on the handle part of the wheelbarrow support frame for easily release the container during removing load process. The lever is joined to a pivotal hook which is mounted on the body of the support frame by a cable. The container includes a fixture on the lower part rear end of the container. This is to secure the container to the releasable locking system when in loading or moving position. With the grasping of the lever, a tension force is formed and thus pulled the pivotal hook backward away from the hooked position. This releases the container from its secured position and can be easily lifted for emptying purposes.
