  • Patent number: 10315360
    Abstract: A manufacturing method of structures formed co-bonding second structural components to a first structural component. The method comprises the following steps: a) preparing for each second structural component an ensemble wherein a preform of the second structural component, surrounded by a band of a suitable material to form a vacuum bag, is disposed between curing tools which are thus in contact with the bag and not with the preform; b) positioning the ensembles on the first structural component and forming the vacuum bag for the complete structure joining the bands and complementary pieces; c) applying to the resulting assembly an autoclave cycle.

  • Patent number: 10211077
    Abstract: A method of debonding a temporarily adhesive-bonded carrier-workpiece pair employs a stream of a solvent at a high pressure. The carrier and the workpiece are bonded with an adhesive that is dissolvable in a selected solvent. The workpiece such as a device wafer may have been thinned and processed. The solvent is applied to the adhesive at a high pressure to debond and dissolve the adhesive with high throughput. The dissolved adhesive can be recycled and later reused, thus lowering the cost of the whole bonding and debonding process.

  • Patent number: 10194682
    Abstract: A high efficiency airflow management system can be used to reliably and consistently draw air through palletized product stacks with a minimum of energy expenditure. A racking system is provided with a grid of pallet bays separated from an air plenum/chamber by a wall having an airflow opening for each pallet bays. An air seal is formed at the periphery of each opening by resiliently flexible side seals and a top seal to form a highly airtight interface between the pallet assembly and the adjacent airflow opening. When a pressure differential is developed between the chamber and the pallet bay, air is efficiently drawn substantially exclusively through the pallet assemblies with minimal leakage. The flexible sealing arrangement accommodates pallet assemblies with unevenly stacked rows of cases without significant loss of system efficiency.

  • Patent number: 9023163
    Abstract: A method for laminating essentially plate-shaped work pieces with a thermally activated adhesive layer, particularly photovoltaic modules. Work pieces are inserted into a vacuum chamber having a compression element dividing the vacuum chamber in a gas tight fashion that can be raised and lowered by pressure differences. The compression element presses against the work piece which in turn presses against a heating plate which forms a lower side of the vacuum chamber, with processing heat being transferred into the work piece to soften the adhesive. The work piece is first impinged by the compression element with a slight load from approx. 2% to 10% of the defined processing load, and is simultaneously kept below the adhesive activation temperature. Thereafter, the slight load is lifted off the work piece and the work piece is heated to the activation temperature and impinged via the compression element with the processing load.

  • Patent number: 9016342
    Abstract: The bonding apparatus is capable of effectively increasing temperature of a substrate and reducing occurrence of position gaps and poor connection in a process of flip-chip-bonding semiconductor devices to the substrate. The bonding apparatus comprises: a supporting unit for supporting the substrate, on which the semiconductor devices have been adhered by a non-conductive; and a heating/pressing unit for heating and pressing the substrate, the heating/pressing unit having a built-in heat source and a clamping face, onto which the substrate supported by the supporting unit is pressed. The substrate supported by the supporting unit is moved toward the clamping face of the heating/pressing unit so as to preheat the substrate and the semiconductor devices by radiation heat. Then, the semiconductor devices are pressed onto the clamping face of the heating/pressing unit so as to cure the non-conductive adhesive and bond bumps of the semiconductor devices to terminal sections of the substrate.

  • Publication number: 20150107750
    Abstract: An apparatus for laminating a scintillator panel and an imaging device panel includes a chamber, a membrane, a first vacuum pump, a second vacuum pump, a heater plate, and a heater power supply. The chamber includes a chamber cover, defining a sealed space. The membrane defines the sealed space in the bottom of the chamber cover by being coupled to the bottom surface of the chamber cover and is made of a contractable and expandable material. The first vacuum pump is coupled to the chamber cover and vents vacuum in the sealed space between the bottom surface of the chamber cover and the membrane. The second vacuum pump vents vacuum in the chamber by being coupled to one side of the chamber. The heater plate is coupled into the chamber to support and heat the panel assembly with an adhesive interposed between the scintillator panel and the imaging device panel.

  • Patent number: 9005390
    Abstract: A room temperature bonding apparatus includes angle adjustment means supporting a first sample stage holding a first substrate so as to be able to change a direction of the first sample stage; a first driving device driving the first stage in a first direction; a second driving device driving a second sample stage holding a second substrate in a second direction not parallel to the first direction; and a carriage support table supporting the second sample stage in the first direction when the second substrate and the first substrate are brought into contact. The apparatus can impose a load exceeding a withstand load of the second driving device on the first and second substrates. Further, the apparatus uses angle adjustment means to change direction of the first substrate to be parallel with the second substrate and uniformly impose the larger load on a bonding surface.
