  • Patent number: 12322690
    Abstract: One or more implementations of the subject technology may enable a bond-on-pad (BoP) substrate technology that can eliminate the need to utilize a solder-on-pad (SoP) process. Unlike an SoP process, a BoP Process does not require a solder bump to be formed on a bump pad to attach a joint to a bump pad. The size of an opening on a bump pad for a BoP process may be larger than that of an SoP process. A BoP process may use a solder mask having multiple thicknesses and may be thinner near the bump pads. A BoP process may use a joint having a copper pillar and a solder cap. A BoP process can be used with an underfill or a molding compound technology.

  • Publication number: 20240203898
    Abstract: An EM shielding structure for a semiconductor package is embedded in a through hole of a core layer of the semiconductor package. The EM shielding structure may include multiple vias formed by a copper plating operation. Additionally, a metal way surrounds the EM shielding structures and prevents, along with a dielectric material, unwanted EM radiation (passing through the vias) from emanating throughout the semiconductor package. The EM shielding structure can also take the form of an insert that is adhered to the core layer at a through hole of the core layer.

  • Patent number: 10206534
    Abstract: A system, device and method for the brewing of a capsule. The device comprises a first chamber portion and a second chamber portion movable with respect to each other to be moved between an open position and a closed position. The device further comprises a capsule handler arranged to enable insertion therein of the capsule and to position said capsule in a brewing position, wherein the capsule handler retains the capsule in the brewing position when the capsule handler is in a ready position. When the first chamber portion and the second chamber portion are moved with respect to each other from the closed position to the open position, the capsule can fall freely from the brewing position under the influence of gravity when the capsule handler is in an ejection position.

  • Patent number: 9027465
    Abstract: A holder and method for obtaining a holder, wherein the holder is provided with a first and a second wall part. The first and second wall part are interconnected such that therebetween at least a first storage space, at least a first fluid connection and at least a first seal removable through fluid pressure and defining an opening are formed. The at least first removable connection is communication with the first storage space and seals a communication to or from the at least first fluid connection. With the method for obtaining the holder, prior to forming the connection of the first and second wall parts, a lacquer is locally applied to one of the first and second wall parts, which after connection results in a controlled reduced adhesion for obtaining the at least first removable seal. Here in the proximity of the removable seal, an additional connection of the first wall part to the second wall part is provided.
