Hull cell test piece for testing leveling performance and Hull cell test piece test method

The invention provides a Hull cell test piece for testing leveling performance and a Hull cell test piece test method.The Hull cell test piece serves as an electroplating cathode, the Hull cell test piece comprises a front face in a bright state and a back face which is in a semi-bright state and is subjected to insulation treatment, 1-10 grooves are formed in the front face of the Hull cell test piece, and the back face of the Hull cell test piece is provided with a plurality of grooves. The groove transversely penetrates through the two ends of the Hull groove test piece, the depth of the groove is 10-30 microns, and the width of the groove is 80-120 microns. Compared with the prior art, the method has the advantages that the tedious steps of testing the leveling capacity of the electroplating mixed liquid under different current densities are simplified, the test piece does not need to be cut when the test piece of the Hull cell is observed, nondestructive testing can be achieved, and resource waste is red
