is not engineered to run cleanly, no amount of filtering in the customer fab is going to make it clean. The process--not just the materials, but the way the fluid is dispensed onto and removed from the wafer, the way the wafer and the optics interact with the moving air-liquid interface, and the way the fluid

Ask Doc, Scale Response Time
Congratulations! Once again, you are being asked to squeeze more speed out of your weight-based process. Where is it going to come from this time and how are you going to get the scale to settle fast enough to keep up with the rest of the process?. We often turn to digital filtering to provide

They are especially suited to high-performance liquid chromatography, microfiltration, venting media, test-strip blotters, and other uses in which the filtering of gases and liquids or wicking of liquids is required. , 15 Ray Trainor Dr

9 Tips from OSHA to Help Reduce Silica Hazards
Crystalline silica is a mineral compound made up of silicon and oxygen, the two most abundant elements on earth. It is commonly found in sand, stone, concrete, plastics, polishing compounds, filtering media and soil, among many other products. Although it is typically not hazardous as part

Where foam fits in medical design
for a versatile, high-tech material that meets a range of application needs. It filters. The permeable cell structure of reticulated, open-cell urethane makes it well suited for filtering, primarily because the open-pore structure leaves plenty of room to capture and hold airborne or liquid contaminants. The high

Less noise and vibration with foam
foams to meet requirements for filtering, gasketing, cushioning, noise and vibration-absorption, and heat shielding. Reticulated polyurethane provides a two-part foam filter that protects the generator engine from harmful particles. A prefilter of open-cell foam (10 parts-per-inch (ppi)) catches
