Kelvin test fixture for electrically contacting miniature, two terminal, leadless, electrical components

A Kelvin test fixture for electrically contacting two terminal, leadless, miniature, electrical components for measurement of their electrical parameters, said test fixture comprising:

• a substantially rigid insulating member having first and second opposed major surfaces;
• first and second conductor means each having a component contact portion rigidly mounted on said first major surface, said first and second conductor means being electrically insulated from each other and being spaced apart from each other;
• insulating spacer means mounted on said first major surface adjacent said component contact portions of said first and second conductor means, said spacer means having a support surface spaced from said first major surface;
• third and fourth conductor means rigidly mounted on said support surface, said third and fourth conductor means being electrically insulated from each other and being spaced apart from each other, each of said third and fourth conductor means extending beyond said support surface at an angle thereto and terminating in a component contact portion overlying said component contact portions of said first and second conductor means, said third and fourth conductor means being flexible so that upon insertion of an electrical component between said component contact portions said component spreads said component contact portions apart.
