ABSTRACT:
An evaluation board for evaluating electrical characteristics of an IC package has an electrically insulating support board having signal wire patterns for contact by a measurement probe formed on a first surface and mounting pads for contact with solder balls of an IC package formed on a surface. The signal wire patterns and the mounting pads are electrically connected with each other via through holes formed in the support board. The signal wire patterns are surrounded by and spaced from a ground pattern formed on the first surface.
