This is a test device that plating a disk-type test piece (φ64xt03mm) while rotating it with a motor. The effect of agitation speed at a constant current density can be obtained on a single test piece. The effect of the additive on the agitation speed is noticeable.

What you can see in the agitation effect test

・Plating films with uniform current density, but varied agitation speed, can be obtained on a single test piece.
・Uniform current density distribution can be obtained by the use of a shield-plate (accessory).
・Agitation speed (peripheral speed) proportional to the diameter is generated on the test piece.

Usage Example

・For quality control of high-speed plating solutions
・For basic experiments of precise plating on silicon wafers
・For control of barrel plating and regular plating solution

By using it in combination with High Speed Plating Hull Cell , which can investigate the distribution of current density at a constant speed, more multifaceted analysis can be performed. Most of the parts are shared, so please use the set (A-45WJ-T) that can analyze both.

Principle of Agitation Effect Test for High Speed Plating ( AEHS )

Agitation Effect kit for High Speed Plating (AEHS kit) is the equipment needed to apply the Hull Cell Test for high Speed plating, HCHS. AEHS is the method for observing the plated results according to different agitation speeds with the same current density, while HCHS is the method for observing plated results according to different current densities with same agitation speed.

In AEHS, using the rotational disc cathode, both the low and high agitating speeds are achieved at the same time, on one cathode plate, with the same current density. By the effect of the shield plate, an almost uniform current density is achieved in the region of r = 0.5 ~ 2.5 cm, where r is the distance from the rotational axis. The diameter of the test piece is 64 mm, and the effective area to be plated is 0.31 dm2. The rear side of test piece is coated with insulating film.
