  • Patent number: 9120170
    Abstract: An apparatus for placing and mounting solder balls on an integrated circuit substrate contains: a fixture, a vacuuming device, a guiding plate, and a storage tank. The fixture includes a plurality of first grooves defined therein, the vacuuming device is disposed over the fixture and includes a vacuum chamber which has an air pore so that when air is drawn out of the vacuum chamber via the air pore, a plurality of solder balls are attached, and when the air is fed into the vacuum chamber from the air pore, the plurality of solder balls are released. The guiding plate is secured below the fixture, and the storage tank is arranged below the guiding plate and is applied to accommodate the plurality of solder balls. Thereby, a production yield of placing and mounting the plurality of solder balls on an integrated circuit substrate is enhanced.

  • Publication number: 20090079462
    Abstract: A semiconductor device testing apparatus includes a test head Hifix, a tester coupled to the test head Hifix, two or more device-under-tests (DUTs), and one or more processor devices disposed on the test head Hifix and coupled to the DUTs for transmitting and receiving test signals between the tester and the DUTs and for receiving and processing a number of test signals from the DUTs into a single output signal and for transmitting the output signal to the tester for testing purposes. The tester may generate and transmit test signals to the test head Hifix and the DUTs for testing the DUTs to ensure that the DUTs function properly in the consumer domain.
