PROBLEM TO BE SOLVED: To provide a probe card capable of protecting a probe head during an etching process to reduce defective rate of the probe cards. SOLUTION: This probe card which uses a thermoplastic resin includes a printed circuit board; the probe head provided on its one face, with a plurality of terminals; connected electrically to the printed circuit board; a plurality of probe chips electrically connected to the plurality of terminals and arranged on the other face of the probe head. At least the other face of the probe head is formed of the thermoplastic resin. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a packaging technology for a thermocompression bonding device having a simple constitution, wherein electrical components can be packaged efficiently, using an adhesive. SOLUTION: The thermocompression bonding device is provided with a stage 2 of rigid material, a compression-bonding member 3 of elastic material which is attached to the stage 2, and a heating mechanism 4 which is arranged above the compression-bonding member 3 to face each other, being movable in the vertical direction. At a main part 40 of the heating mechanism 4, a heating pressurizing surface 40a whose size corresponds to a heating region for the adhesive used for thermocompression bonding is formed.

Abstract:
Several different types of electrically conductive elastomers are disclosed along with the methods for their fabrication. In one particular embodiment, a layered composition is disclosed which comprises a substrate, a first layer, and a second layer. The substrate is formed of a non-conductive elastic material and it has an outer surface. The first layer, which is formed with a non-conductive elastic material, is grafted to the outer surface of the substrate. The second layer, which is formed with a non-conductive elastic material having a quantity of conductive flakes interspersed therein, is grafted to an outer surface of the first layer. The second layer can further be formed with a quantity of rounded or jagged conductive particles interspersed in the non-conductive elastic material such that some of the conductive particles are present along an outer surface of the second layer. Alternatively, a quantity of rounded or jagged conductive particles may be imbedded in an outer surface of the second layer.
