  • Patent number: 7151388
    Abstract: A method for testing integrated circuit devices and loading such devices into a test board for further testing and an apparatus therefor is disclosed. The method allows for selection between two modes of operation. In a first mode, the integrated circuit devices are subjected to an electrical test before being placed into the test board for further testing. In a second mode, the integrated circuit devices are tested after being placed in the test board. The apparatus allows for the selection between the first mode and the second mode. In either mode, information about the tested devices and the sockets in the test board is used to load the test boards intelligently. Intelligent loading means that devices under test (DUTs) are not placed in bad sockets and devices that do test bad are removed from the test board, with an option of replacing the failed DUT with another DUT before subsequent environmental testing of the DUTs in the test board is carried out.

    Abstract: The invention provides methods for marking packaged ICs. In a first embodiment, only the minimum performance information is first marked on the package, regardless of the actual performance of the IC. This method avoids a second marking step for all ICs sold as low-performance ICs. In another embodiment, only one inking and curing step is required for all ICs. According to this method, all specified performances are marked on the packaged IC at the first marking. The IC is then tested to determine the actual performance, and all performance markings not applicable to the IC are removed, preferably with a laser. Alternatively, all applicable performance markings are identified (e.g., underlined or enclosed with a laser marking).

  • Patent number: 6578261
    Abstract: In a part-mounting system formed by linking plural part-mounting devices which carry out respective process steps of part-mounting, when a production tact-time of one of the devices varies beyond a given variation range, a tact-time change signal is sent to other devices located at upstream and/or downstream of the device via a communicating section. The other devices receive the tact-time change signal and changes their own work tact-times from the ones corresponding to a productivity-oriented mode to a slower tact-pattern corresponding to a quality-oriented mode. Thus every device constituting the system can accommodate a tact-time variation due to a tact-time delay of any part-mounting device. As a result, the quality appropriate to the tact-time can be secured.

  • Patent number: 6563070
    Abstract: A semiconductor device sorting method and apparatus involve development of small, self-contained and focused “qualification” or “sort” algorithm test programs or “modules”, each of which modules may test for the validity of a particular, selected grade of a memory or other semiconductor device based on the results of a test pattern associated with, or exhibited by, a particular device under test. Separating the test code from the main flow file of the test program into the aforementioned “plug-in” qualification or sort modules permits the test code to be much simpler and facilitates better organization, as each qualification or sort module may be independent of any other qualification or sort module and only determines in response to its associated test pattern whether or not (TRUE or FALSE) a device qualifies in a given device grade.

  • Patent number: 6525528
    Abstract: An automatic ROM burning device, comprising a support plate that is erected almost vertically. On the surface of the support plate is at least one feeder chute, inside which is inserted an IC rod, enabling the ROM component inside the IC rod waiting to be burned with data to lower in sequential order by gravity, while a moving mechanism moves it under the control of a control unit into a burner unit. The burner unit serves to conduct data burning and test operation on the components under the control of a control unit, and categorize the components according to the results obtained from the burning and testing operation. After data burning is completed, a moving mechanism delivers the components to a moving unit, moving the categorized components to separate discharge troughs; those of the same category are guided into empty IC rods for discharge.

  • Patent number: RE38894
    Abstract: There is an IC (integrated circuit) testing device 11 that receives singulated ICs from a singulation station's bottom table 44, where an IC 15 has slid down onto loading ramp or track 16. The IC will slide into test station 18, where stop pin 22 has been inserted to stop the IC in DUT (device under test) station 20. In the DUT station, the IC is securely held in position by an extractor bar 26, insertion bar 28, and a part guide 24. Thereby, test cite station 18 will move downward and insert IC 15 into testing socket 30. After testing the IC, testing station 18 returns upward with IC in the same secured position. Pin 22 will be removed to allow the IC to slide into part holding station 31. If the IC was not defective, pin 32 will be removed to allow the IC to slide onto track 36 of the IC separator station 34. While the test cite station 18 is in the up position a second IC is slid along track 16 and loaded into DUT cite 20 being readied for the next test cycle.
