Abstract

To make the test probe not directly in contact with the electrode pads for the semiconductor chip mounting, without using an advanced technology for making the pitch of electrode pads narrower, and remove the chip mounting failures such as scratching of electrode pads caused by testing, adherence of impurity particles, electrical corrosion. The electrode padsformed on the distal ends of the external leadsfor press-connecting the input electrodesof the semiconductor chipare disposed at both sides (shown as L) of the semiconductor chip. The terminal-electrode leadsfrom the electrode padspass under the semiconductor chipwhile keeping a pitch of the electrode pads. The test electrode padsare disposed in alternate arrangement on the distal ends of terminal-electrode leads. The test electrode padsmay be disposed in alternate arrangement in three steps or more of multiple steps.
