  • Publication number: 20140102850
    Abstract: An apparatus for processing electronic devices includes a rotary turret having first device concentric around the rotary turret, which transfer the electronic devices; a rotary wheel having second device holders concentric around the rotary wheel, which receive the electronic devices and a processing device to process the electronic devices. The rotary turret rotates the first device holders along a first circular path, and the rotary wheel rotates the second device holders along a second circular path. The first axis of the rotary turret is perpendicular to the second axis of the rotary wheel, and that a projection of the second circular path of the second device holders in a direction perpendicular to the second axis of the rotary wheel onto the first circular path of the first device holders defines a line from the inside to the outside of the first circular path of the first device holders.

  • Publication number: 20140049279
    Abstract: A testing apparatus for electronic components comprises a mounting block and a plurality of contact strips arranged on the mounting block. The contact strips are configured such that electrical leads of an electronic component are operative to press against and bend the contact strips in a biasing direction to ensure good contact between the electrical leads and the contact strips during testing of the electronic component. Further, a preload block located on the mounting block is operative to contact and apply a pre-stress force onto the contact strips in the biasing direction prior to contact between the electrical leads and the contact strips.
