Document Type and Number:
WIPO Patent Application WO/2010/055872
Kind Code:
A1
Abstract:
Provided is a spherical shell contact capable of exhibiting a high elastic force independently of the directivity of an external force application direction by using a simple constitution. Also provided is a method for manufacturing the spherical shell contact.
The spherical shell contact (1) is equipped with a spring portion (2) which is formed into a partially buried spherical shell shape in such a manner that a portion of the spherical shell is buried in a wiring board (4) to be used in a probe card and that at least one through hole is formed. In the method for manufacturing the spherical shell contact (1), the spring portion (2) is plated by using, as a mold, a resist sphere formed by thermally setting a resist pillar formed on the wiring board (4).
