An tape automated bonding feeder apparatus employs a vertical carrier extraction unit to successively supply electronic circuit components to an output station from which a component is seized for placement and attachment to a circuit board. The feeder apparatus, which may be mounted on a rollable cart, includes a generally rectilinear housing on a top plate of which one or more magazines are mounted. A magazine contains a stack of circuit component carriers. The bottom of the magazine has a carrier extraction unit which controllably allows an individual component carrier at the bottom of the stack to drop away onto an underlying carrier shuttle. The carrier shuttle is supported for movement betweeen the magazine and a lead forming unit. The lead forming unit detaches a component from the carrier and forms the leads of the excised component for mounting the component to a circuit board. A processed component transport unit is coupled to an anvil of the lead forming unit and transports a processed component to the output station.

A mechanism for straightening bent terminals on an integrated circuit package comprises a base having a pair of spaced apart arms pivotally coupled thereto. Rollers attach to the arms to support and move a plate when the arms are pivoted. The plate has a first set of holes which are tapered to accept bent terminals and to straighten them when they are forced into the taper. A plurality of pins extend from the base between the arms and stop parallel to the plate. The plate has a second set of holes through which the pins move when the arms are pivoted. A plurality of intermeshed gears couple to the base and the arms to pivot the arms in synchronization and move the plate perpendicular to the pins which push the integrated circuit package straight out of the first set of holes.

The invention is a multi-channel position detection system which utilizes several separate emitters and a single photodetector to, for example, align a multi-lead component manipulator with a predetermined location in a printed circuit board. An oscillator circuit generates a modulated signal for each emitter and a multiplier circuit develops an output signal based upon the oscillator output and the photodetector output. The photodetector provides an output responsive to the emitter signal as attenuated by the circuit board location relative to the emitter. When the lead hole of the circuit board is aligned with the emitter and photodetector minimum attenuation of the signal occurs.

An integrated circuit comprises a package and having adjacent connection pins on two opposite sides of the package, with every second connection pin being inwardly bent so that the connection pins are offset. The ends of the inwardly bent connection pins and the ends of the outer connection pins each lie on a straight line, where the offset connection pins are bent by different angles out of the plane of the package.

In a component insertion apparatus, there are provided a component insertion apparatus and a component insertion method capable of realizing productivity improvement by simplifying apparatus construction, downsizing the apparatus and further reducing the time required for component insertion. In a component insertion head, by grasping of a device portion of a component by a device chuck, a lead wire is stretched on a fulcrum given by a grasping position of the lead wire by a transfer chuck so that the device portion comes to be placed at a component insertion position, by which correction of insertion posture of the component is performed, and the lead wire of the component that has been corrected in its insertion posture is inserted into an insertion hole of a board.
摘要:
The invention relates to the fabrication and testing of a chip with a package (2) having connecting pins (1) as well as to mounting the package (2) on a board (5), whereby in order to combine the advantages of a package (2) with inline connecting pins (1) with the advantages of a package (2) with offset connecting pins (11, 12), the package (2) is fabricated with inline connecting pins (1) and inserted into a test socket (3) for testing. Immediately before mounting on the board (5), at least one connecting pin, preferably every second connecting pin (12), of the package (2) is bent inward by a bending tool (6) so as to achieve an offset arrangement of the connecting pins (11, 12). The package (2) is preferably mounted on the board (5) using the bending tool (6). A simple, inexpensively produced test socket (3) is sufficient for the purpose of testing the chip. An inexpensively produced guide brace (4), for example, is suitable as a packaging means. Since every second connecting pin (12) is not bent inward immediately before insertion of the connecting pins (11, 12), no subsequent corrective alignment of the offset connecting pins (11, 12) is required.
