  • Method for building and a structure of a contact end in a contact probe
    Patent number: 6111418
    Abstract: In the contact probe 1 having an array of leads 3 densely attached to a surface of an insulative film 2, pressure contact ends are formed by one end of the leads 3 being arranged in an array along one end edge portion of the insulative film 3. Slots are formed in the one end edge portion of the insulative film 2 such that the slots 9 are open between adjacent contact ends. When the lead ends arranged in the array on the surface of the insulative film are contacted under pressure with a given electronic part, a sufficient degree of freedom of flexure of the contact ends is obtained, so that the contact ends are contacted under pressure with the external terminals of the electronic part.
