Abstract
Abstract A test probe assembly including a plurality of electrically conductive probe arms each of which is secured to a substrate and electrically coupled to one of electrically conductive lines provided on the substrate. An intermediate portion of the arm is arranged to be resiliently deformable when a probe point which extends therefrom comes into contact with a terminal of the electronic device under test. A guide is provided on the structure on which the arms are mounted, for guiding the probe point so that movement other than reciprocation is either prevented or arrested. The resilient portion is arranged with respect to the probe point so that generation of motion other than reciprocation of the probe point is attenuated.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
109 words
A multi-point test probe assembly including a support structure and a plurality of probe arms supported by said support structure, said support structure comprising means defining an open sided channel which extends in a direction substantially perpendicular to said probe arms and a plurality of open sided probe-receiving channels which are parallel to said probe arms; each of said probe arms comprising: a probe portion which is arranged to contact a terminal of a device under test; a mounting portion which is connected to said support structure; and a spring portion interconnecting said probe portion and said mounting portion, said spring portion being received in said open sided channel.
Claim 2
Dependent Claim
109 words
A multi-point test probe assembly including a support structure and a plurality of probe arms supported by said support structure, said support structure comprising means defining an open sided channel which extends in a direction substantially perpendicular to said probe arms and a plurality of open sided probe-receiving channels which are parallel to said probe arms; each of said probe arms comprising: a probe portion which is arranged to contact a terminal of a device under test; a mounting portion which is connected to said support structure; and a spring portion interconnecting said probe portion and said mounting portion, said spring portion being received in said open sided channel.
Claim 3
Dependent Claim
49 words
A multi-point test probe assembly as claimed in claim 1, wherein said probe arms are aligned along said support structure with each of said probe arms being spaced by a predetermined distance and arranged to be brought into contact with a plurality of terminals of the device under test.
Claim 4
Dependent Claim
43 words
A multi-point test probe assembly as claimed in claim 1, wherein said multi-point test probe assembly further comprises: a probe guide member defining a plurality of grooves in a surface thereof, with each of said plurality of grooves slidably receiving a probe arm.
Claim 5
Dependent Claim
131 words
A multi-point test probe assembly including a support structure and a plurality of probe arms supported by said support structure, said support structure comprising means defining a channel which extends in a direction substantially perpendicular to said probe arms; each of said probe arms comprising: a probe portion which is arranged to contact a terminal of a device under test; a mounting portion which is connected to said support structure; and a spring portion interconnecting said probe portion and said mounting portion, said spring portion being received in said channel, wherein said channel is provided with a supporting fulcrum member, with said spring portion of each probe arm being positioned within said channel so as to be supported at said supporting fulcrum member so that said spring portions are elastically deformable.
Claim 6
Dependent Claim
131 words
A multi-point test probe assembly including a support structure and a plurality of probe arms supported by said support structure, said support structure comprising means defining a channel which extends in a direction substantially perpendicular to said probe arms; each of said probe arms comprising: a probe portion which is arranged to contact a terminal of a device under test; a mounting portion which is connected to said support structure; and a spring portion interconnecting said probe portion and said mounting portion, said spring portion being received in said channel, wherein said channel is provided with a supporting fulcrum member, with said spring portion of each probe arm being positioned within said channel so as to be supported at said supporting fulcrum member so that said spring portions are elastically deformable.
