Abstract:
A cathode cartridge of a testing device for electroplating, said cathode cartridge comprising:a plated base having a plated part acting as a negative plate; a tabular cathode conductor having an open hole having the same shape as said plated part of said plated base, said cathode conductor having a plurality of protruding portions that press contact to a peripheral part around said plated part, and which is able to connect with a direct current by an exposed portion thereof not soaked in plating solution; a first elastic thin board covering a rear side of said plated base and having a recess into which said plated base is retained; a tabular rear wail insulator covering both a back side of said plated base and a back side of said first elastic thin board, and having a recess into which said plated base and said first elastic thin board are retained; a tabular front insulator having an open hole having the same shape as said plated part, said front insulator covering a front side of said cathode conductor and having a recess into which said cathode conductor is retained; and a second elastic thin board having an open hole having the same shape as said plated part, said second elastic thin board being sandwiched between said cathode conductor and said plated base, and having a plurality of holes by which said protruding portions of said cathode conductor are guided for passing therethrough.
