Abstract
The invention provides, in one embodiment, a device for performing scrub testing on a plurality of samples simultaneously, including a plurality of scrubbing devices. A stage is provided which positions the plurality of samples in contact with the plurality of scrubbing devices. The scrubbing devices can individually be provided with different weights to produce different forces on the samples. A motion producing device produces one or both of linear and rotational motion between the brushes and the samples. The scrubbing devices are held in the stage so as move freely vertically.
Claims14
A device for performing testing on a plurality of samples simultaneously, comprising:
- a scrubbing device array including a plurality of scrubbing devices;
- a sample stage for holding the plurality of samples in contact with the plurality of scrubbing devices;
- and
- a motion producing device for producing non-linear motion of the sample stage while the scrubbing device array is maintained in a fixed position, wherein the non-linear motion of the sample stage produces non-linear motion between the plurality of scrubbing devices and the plurality of samples in contact therewith.
