Abstract:
A cathode cartridge for an electroplating tester comprising:a tabular cathode conductor that includes an opening having the same contour as a surface to be plated of an object to be plated as a negative, a plurality of protrusions in contact with a rim of the surface to be plated, and a power-supply connection portion connectible with a power supply at a portion thereof which is not to be immersed in plating solution; a tabular first insulator that covers one surface to be plated of the object to be plated and includes an opening having the same contour as the surface to be plated, a first sealant fit-in groove which is formed along a circumferential edge of the opening and into which a first sealant is fitted, a cathode conductor fit-in groove which is formed at an outside of the first sealant fit-in groove and into which the cathode conductor is fitted, and a power-supply connection portion slot which is formed contiguously with the cathode conductor fit-in groove and into which the power-supply connection portion is fitted; and a tabular second insulator that covers the other surface reverse to the surface to be plated of the object to be plated and includes an object-to-be-plated fit-in groove into which the object to be plated is fitted, a second sealant fit-in groove which is located at an outside of the object-to-be-plated fit-in groove so as to come in a position outside an inlet of the power-supply connection portion slot when the second insulator is combined with the first insulator and into which a second sealant is fitted, wherein the first insulator and the second insulator are combined together so that the first insulator and the second insulator sandwich the object to be plated and the cathode conductor.
