  • Publication number: 20140242330
    Abstract: The present invention relates to an irregularly formed waterproof panel having a hollow protrusion for waterproofing, and to a waterproofing construction using same. The present invention provides: an irregularly formed waterproof panel in which a complex waterproofing layer is formed using the irregularly formed waterproof panel having a hollow protrusion to prevent a waterproofing foundation from being cracked or to prevent a waterproofing layer from being damaged due to the behavior of a joint, and to provide permeability to air; and a waterproofing construction using same.

  • Publication number: 20100207652
    Abstract: A method of testing a wafer capable of minimizing the asymmetrical thermal deformation of a probe card when a wafer is tested using a probe card and of minimizing the number of times of tests to effectively test a large area wafer and a probe card for the same is presented. For the wafer test method for testing semiconductor chips on a wafer using a probe card, the method includes creating virtual repeating units corresponding to N semiconductor chips, wherein the N is natural number larger than or equal to 2, arranging the plurality of repeating units on the wafer and moving the probe card or the wafer N times and testing the semiconductor chips on a wafer, wherein the semiconductor chips in the repeating units are sequentially tested one by one per each touchdown. Also, the probe cards to realize above mentioned method have been described.

  • Patent number: 6956386
    Abstract: A probe card has probe sections with silicon probes formed on an insulated circuit board that are connected by an adhesive on the supporting structures. The supporting structures are supported by fixing structures with each of the fixing structures being fixed on the circuit board. The probe card has the probe section's wiring and the circuit board's wiring being electrically connected by a metallic wiring and the sub printed circuit and the pogo pin electrically connected by an anisotropic conducting film with the sub printed circuit board and the pogo pin. A metallic layer is formed by the plating of the probe in the probe section. This reduces the manufacturing costs by enabling the damaged probes during manufacturing to be discarded and the others being used continually.

  • Patent number: 6414501
    Abstract: The present invention is to provide a micro cantilever-type probe disposed on a probe card, having such appropriate elasticity and mechanical strength that the probe would recover its unforced shape after deformation during an inspection and maintain its original shape even after three hundred thousand uses. The present invention provides a probe card which has an electrically insulated substrate fixed on a circuit board; a plurality of elastic probes with a sharpened end fixed on the insulated substrate; and wiring formed on the probe, the insulated substrate and the circuit board. The inventive probe is manufactured by patterning a substrate using photolithography and etching a portion except a pattern-defined portion. The probe is coated by metal layer(s).
