Abstract:
A peeling device is provided for detachment of a chip from an adhesive tape on which it is mounted. The device comprises a platform including a first surface and a raised contact surface set at a determinate height with respect to the first surface. The raised contact surface has a width that is smaller than a width of the chip for contacting the adhesive tape at a position of the chip. Further, an elevation device is projectable from the raised contact surface and movable with respect to the platform for lifting the chip away from the adhesive tape.
Abstract:
Adhesive is dispensed for conducting die bonding onto a substrate including rows of bond pads aligned along a first axis and columns of bond pads aligned along a second axis transverse to the first axis where target dispensing positions are located. A first dispensing head incorporating a first nozzle and a second dispensing head incorporating a second nozzle are provided and the substrate is fed along the first axis to a position where the first and second dispensing heads are located. Pattern recognition of a columnar section of the substrate comprising one or more consecutive columns of bond pads with an optical system may be conducted by moving the optical system along the second axis relative to the substrate. Thereafter, the first nozzle and the second nozzle are driven concurrently to dispense adhesive from the first and second nozzles onto the target dispensing positions in the same columnar section of the substrate.
Abstract:
A bonding apparatus (10) for bonding a length of wire comprises a first module (14) which is drivable along a linear axis towards and away from a bonding point and a second module (16) slidably mounted to the first module (14). A wire cutter (36) is mounted to the first module (14) and a bonding tool (32) is mounted to the second module (16). A coupling mechanism is operative to lock the second module (16) in fixed relative position to the first module (14), and to unlock the second module (16) from its fixed relative position to the first module (14) so that the second module (16) is slidable relative to the first module (14) in directions parallel to the linear axis.
Abstract:
A method for mounting a semiconductor chip onto a substrate (12) comprises the steps of positioning a solder dispenser (10) over the substrate (12) and passing a length of solder wire (24) through the solder dispenser (10) to the substrate (12). The feeding of the wire (24) to the substrate (12) is a feeding direction is controlled with a wire feeder. The solder dispenser (10) is moved relative to the substrate (12) with a positioning device (17) along at least one of two orthogonal axes that are substantially perpendicular to the feeding direction contemporaneously with feeding the solder wire (24) to the surface of the substrate (12) to dispense a line of molten solder onto the substrate (12). The semiconductor chip is then mounted onto the molten solder that has been dispensed onto the substrate.
Abstract:
The invention provides a pick and place assembly for transferring a film of material. The assembly comprises a collet having a substantially convex contact surface for contacting the film, the collet including a vacuum suction device operative to generate a force to hold the film. The film may comprise a thermoplastic adhesive tape or B-stage thermoset epoxy coated film.
Abstract:
An apparatus and method is provided for detaching a semiconductor chip from an adhesive tape on which it is mounted. The apparatus comprises a platform adapted to contact the adhesive tape at a position of the chip and a retaining force generator coupled to the platform for drawing the adhesive tape in a direction away from the chip. An elevation device is projectable from the platform that is movable both laterally across a surface of the platform and vertically with respect to the platform for elevating the chip. By moving the elevation device across a width of the chip while lifting the chip, controlled lifting of the chip and propagation of delamination between the chip and the adhesive tape may be achieved
Abstract:
This invention relates to a method and apparatus for pick and place handling of electronic components (7) that have been formed on a common substrate and then separated on a cutting chuck (5). A transferring means (4) is provided formed with openings for receiving separated components. The opening is defined by walls (1, 2) of which at least one (2) is movable so as to engage the components (7) and hold them in a fixed configuration and orientation while they are moved by a sliding motion through a processing unit (3) and onto a transfer platform for delivery to an output track.
Abstract:
The invention provides an ultrasonic cleaning module and a method for cleaning singulated electronic packages. The module comprises a cutting chuck (13) having a surface with a plurality of cutting recesses defined in it for enabling a cutting device to separate individual electronic packages from a substrate (1) having a plurality of electronic packages on the surface of the chuck. A pulsator nozzle (14) is supported above the chuck (13) and the separated electronic packages on the chuck such that the pulsator nozzle may emit fluid toward the packages. An ultrasonic generator (17) is associated with the nozzle (14) that is adapted to ultrasonically energize fluid that passes through the nozzle (14) to enhance cleaning of the packages.
