Title:
SEMICONDUCTOR TEST APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/081864
Kind Code:
A2
Abstract:
Proposed is a semiconductor test apparatus which enables components and terminals of an object to be tested to be arranged as close as possible. The proposed semiconductor test apparatus comprises a printed circuit board, and a test socket mounted on an upper surface of the printed circuit board to form a signal connection path between the object to be tested and the printed circuit board. A chip-type capacitor is mounted on the upper surface of the printed circuit board, and the test socket has an interference preventing space for preventing contact with a capacitor. The interference preventing space is formed in the location which faces the location of the capacitor. The capacitor and the test socket are prevented from contacting with each other by the interference preventing space. Differently from conventional systems, components are mounted on an upper surface of a DUT PCB, and a mechanical design of a test socket is changed to prevent a mechanical interference with the mounted components, thus enabling components to be arranged as close as possible to the upper surface of the DUT PCB, and dramatically improving a semiconductor test environment. Meanwhile, an intermediate PCB is interposed between the object to be tested and the DUT PCB, thereby increasing a space for signal improving components used for optimizing a signal for testing the object to be tested. In addition, it is easy to arrange the signal improving components between signal transmitting lines as close as possible to the terminals of an object to be tested.
