Roughometer with skid also works very well on our footprints.

The roughometer is a contact measuring machine that allows you to quickly determine the roughness of a surface.

Despite this defect, roughometers with skid are a very handy and efficient way for measuring flat surfaces.

If you can’t get one, choose a skidless roughometer, which is much more suitable for measuring the roughness of an impression.

Whether with the roughometer or the interferometer, the Ra values will be accurate, the only difference will be with respect to the other indicators that will be given with much more precision with an interferometer.

We also have measuring equipment to ensure the quality of our products, including roughness meter, profile projector, three-dimensional machine and others.

When the Ra of the surface to be inspected is greater than or equal to 0.4 µm, the roughness can be measured directly on the impression using a roughness meter, and the result is faithful to the original.

When the Ra of the surface to be inspected is greater than or equal to 0.4 µm, the roughness can be measured directly on the impression using a roughness meter, and the result is faithful to the original.

The average value of the roughness (Rz) of the surface of the ultra thin copper layer as measured in accordance with JIS B0601-1982 using a contact roughness meter is at most 1.5μm, and the standard deviation of the roughness (Rz) is at most 0.1μm.
