Abstract
An apparatus for measuring the electrical characteristic of a chip-shaped electronic component having first and second external terminal electrodes at first and second opposing ends thereof includes a holder that holds an electronic component with the first and second external terminal electrodes pointing toward first and second open ends of a receiving cavity. The holder is provided with a shield layer extending between first and second measuring terminals, and the shield layer is electrically connected to a measurement reference potential. The shield layer reduces the stray parasitic capacitance adjacent to the electronic component, and reduces measurement errors resulting from size variations of the electronic component.
Claims24
An electronic-component characteristic measuring apparatus for measuring an electrical characteristic of a chip-shaped electronic component having first and second external terminal electrodes at first and second opposing ends thereof, the apparatus comprising:
- a holder having at least one receiving cavity for receiving the electronic component, and holding the electronic component with the first and second external terminal electrodes pointing toward first and second opposing open ends of the at least one receiving cavity;
- first and second measuring terminals disposed at the first and second open ends of the at least one receiving cavity so as to come into contact with the first and second external terminal electrodes of the electronic component;
- and
- a shield layer disposed within the holder and having first and second main surfaces, the shield layer including a conductive material and extending between the first and second measuring terminals;
- wherein
- the holder is made of an electrically insulating material;
- and
- both of the first and second main surfaces of the shield layer are sandwiched by the holder, such that the first and second main surfaces of the shield layer are not exposed toward the first and second measuring terminals.
