Claim:
An operating condition determination method for determining an operating condition of a rotary surface treating apparatus for carrying out a desired electroplating to a treatment object, the rotary surface treating apparatus includes a surface treatment part for carrying out electroplating by energizing between an anode provided to a treatment container and a cathode arranged in a direction of the periphery of the container under the condition of shifting the object in a direction of the periphery of the container while outflowing surface treatment solution by rotating the container holding the surface treatment solution and the treatment object therein, and a control part having a storage part for storing a plurality of operating condition parameters, and for controlling the surface treatment part based on the operating condition parameters stored in the storage part, wherein the operating condition parameters stored in the storage part include a plurality of liquid parameters and an energization parameter, the method comprising: carrying out a preliminary test operation for plating treatment by utilizing inputted operating condition parameters which had been previously stored in the storage part; setting the plurality of liquid parameters as a first operating condition according to a result of the preliminary test operation, wherein one of the liquid parameters includes a constant rotation period, wherein the constant rotation period includes a plating delay period and a plating period; carrying out a first test operation by the control part through control of the surface treatment part under the plurality of liquid parameters set as the first operating condition with no energization being carried out; setting the plurality of liquid parameters and the energization parameter as a second operating condition determined based upon the result of the preliminary test operation and the first test operation, so that no energization is to be carried out during the plating delay period, and energization is to be carried out during the plating period; carrying out by the control part a second test operation using the second operating condition under the condition that energization is carried out as set according to the second operating condition; selecting as an optimum operating condition according to the result of the second test operation; and registering the optimum operating condition to the storage part.
