PROBLEM TO BE SOLVED: To provide a product and an assembly for receiving a long and thin mutual contact element such as a spring contact element extending from an electronic part such as a semiconductor device. SOLUTION: A capture pad is provided in a socket board for receiving an end part of a long and thin mutual contact element extending from an electronic part. The structures of various capture pads are disclosed. A fixing device such as a housing surely positions the electronic part on the socket board. Connection to an external device is carried out through a conductive trace adjacent to the surface of the socket board. The socket board can be supported by a support board. In a particularly preferred embodiment, the capture pad is directly formed on a primary substrate such as a printed circuit board. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a microminiature spring contact suitable for probing of an active semiconductor device, and its manufacturing method. SOLUTION: A cantilever-shaped contact element 100 is long and narrow and has two ends 102, 104 and a center part 106 between the ends. The end 102 is a base part, and the contact element 100 is fitted with an electronic part (unillustrated) on the end 102. A coupling fixture 110 is provided on the base part 102. The coupling fixture 110 can be formed as a tab or a stud to facilitate brazing on a substrate at the assembly time. The end 104 is a free end, and a device to be tested is brought into contact with the end 104. An integrated projecting fixture 108, for example, in a pyramidal geometric shape, is provided on the tip 104 to assist connection by pressure to the terminal of the device to be tested. The contact element 100 has a step-shaped structure. The contact element can be easily manufactured by using a known lithography technology. COPYRIGHT: (C)2003,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a means for testing a plurality of integrated circuit devices at the same time. SOLUTION: This system for testing the plurality of integrated circuit(IC) devices (DUT) of testing objects is provided with an interface circuit coupled to a tester to receives a data value from a single channel or a plurality of channels so as to provide error information as to the DUT. The interface circuit transmits the data value (received from the tester via the single channel) to the plurality of DUTs. The interface circuit conducts comarison using the data value read from the DUT, and generates an error value for showing a comarison result in response thereto. The error value is returned to the tester via the same channel or a different channel.

Abstract:
PROBLEM TO BE SOLVED: To provide a device and a method of producing an improved mutual connection element and a tip structure for carrying out pressure connection between terminals of electronic parts. SOLUTION: The tip structure includes a sharp blade, and this blade is arranged so that the length of the blade will become substantially in parallel with a horizontal movement direction of the tip structural when the tip structure bends and crosses the terminals of the electronic parts. In this way, the sharp blade arranged substantially in parallel clearly cuts in through a certain non-conductive layer (singular or multiple), and brings about sure electric connection between the interconnection element and the terminals of the electronic parts.
