Claims (1)

[Claims for Utility Model Registration] 1. A measurement probe assembly for an IC package used when performing electrical characteristic tests, functional tests, etc. of an IC package 38 installed on a printed circuit board 40, which is capable of performing at least two measurements. A probe 14 is provided, each measuring probe having a tapered head member 16 made of an insulating material;
A pair of conductor members 1 are applied in an insulating state to both mutually opposing tapered side surfaces of this tapered head member.
8, the distance between the pair of conductor members is made smaller than the lead pitch spacing of the IC package on the narrow end side of the tapered head member, and the two measurement probes are connected to both tapers of the tapered head member. The two measurement probes are arranged in such a manner that their sides are aligned facing each other, and the distance between the centers of the two measurement probes corresponds to the distance between the centers of the outer lead pitches of the three consecutive lead pitches of the IC package. Measurement probe assembly for IC package. 2 IC described in paragraph 1 of claims for utility model registration
