What is depth profile?

Depth Profiling is a process where the element or chemical content of a sample is measured as a function of depth. The depth profile process involves the repeated removal (or in certain cases, the movement of the sample) down to the desired depth.

What is a profile measurement?

Overview. Profile measurement systems measure and record the profile of a target by tracing the surface of the target using a stylus. Some instruments can even be used as surface roughness meters. These instruments are ideal for measuring minute shapes such as screw threads and thin films in the order of micrometers.

What is ASTM D4417 method C?

ASTM D4417 contains three methods of measuring surface profile depth: Method A describes the proper use of a comparator; Method B describes the use of a depth micrometer, and Method C addresses the use of replica tape (as does NACE SP0287).

How does a depth profile may get obtained on Sims?

SIMS Depth Profiling Thus a depth profile of a sample may be obtained simply by recording sequential SIMS spectra as the surface is gradually eroded away by the incident ion beam probe.

What is depth profiling in XPS?

Monatomic depth profiling uses an ion beam to etch layers of the surface or surface contamination, revealing subsurface information. Combining a sequence of ion gun etch cycles with XPS analyses provides quantified information as well as layer thicknesses.

What is profile projector?

A profile projector is an optical measuring instrument used in metrology and quality control. This device allows the shadow of the part to be measured to be projected on a screen which is then used by the operator to perform the measurements.x. It’s the principle of Chinese shadows, but it still works very well today.

What is press O film?

Press-O-Film consists of a layer of crushable plastic microfoam coated onto polyester film of highly uniform thickness. When compressed, by “burnishing” against a surface, the foam collapses to about 25\% of its pre-collapse thickness. You should feel the roughness as you burnish.

How is profile tolerance measured?

Profile is usually measured using a CMM due to the complexity of some of the surfaces that are called out. The CMM would compare the 3D scan of the profile to the dimensions called out on the drawing to see if it was in spec.

Is Sims able to analyze non conductive samples?

Conducting versus Non-conducting. It used to be the case that non-conducting samples could not be analyzed routinely by XPS or TOF-SIMS. Non-conducting samples will be mounted beneath a grounded metallic mask with a small-diameter aperture exposing the sample area to be analyzed.
