Inline Roughness Inspection Using Chromatic Confocal Optics

Inline roughness inspection of surface defects derive from materials processing and product manufacturing. In-line surface quality inspection ensures the tightest quality control of the end products. The Nanovea 3D Non-Contact Profilometer utilize chromatic confocal technology with unique capability to determine the roughness of a sample without contact. Multiple profiler sensors can be installed to monitor the roughness and texture of different areas of the product at the same time. The roughness threshold calculated real-time by the analysis software serves as a fast and reliable pass/fail tool.

Micro Scrape Test Of Polymeric Coating

Scratch testing has developed to be one of the most widely applied methods to evaluate the cohesive and adhesive strength of the coatings. The critical load, at which a certain type of coating failure occurs as the applied load progressively increases, is widely regarded as a reliable tool to determine and compare the adhesive and cohesive properties of the coatings. The most commonly used indenter for scratch testing is the conical Rockwell diamond indenter. However, when the scratch test is performed on the soft polymeric coating deposited on a brittle substrate such as silicon wafer, the conical indenter tends to plough through the coating forming grooves rather than creating cracks or delamination. Cracking of the brittle silicon wafer takes place when the load further increases. Therefore, it is vital to develop a new technique to evaluate the cohesion or adhesion properties of soft coatings on a brittle substrate.

Abrasion Resistance Of Sandpaper Using Tribometer

Abrasion resistance and the effectiveness of sandpaper is often determined by their abrasion performance under different conditions. The grit size, i.e. the size of the abrasive particles embedded in the sandpaper, determines the wear rate and the scratch size of the material being sanded. Sandpapers of higher grit numbers possess smaller particles, leading to lower sanding speed and finer surface finish. Sandpapers of the same grit number made of different materials can behave differently under the dry or wet condition. Reliable tribological evaluation is needed to ensure that the manufactured sandpapers possess desired abrasion behavior under the application conditions. It allows users to quantitatively compare the wear behaviors of different types of sandpapers in a controlled and monitored manner and to select the best candidate for the target application.
