How Pump-Induced Particles Affect Low-k CMP Defectivity

www.semiconductor.net | Sep 1, 2008

High shear flow generated by positive displacement pumps increases the distribution of oversized particles, leading to significantly increased wafer surface defectivity (scratches or roughness) during CMP, whereas less defectivity was found in slurries circulated by a magnetically levitated

Taking Advantage of Fluid Power

www.designnews.com | Nov 5, 2007

Hydraulics and pneumatics continue to play critical roles in motion control systems. In addition to traditional applications for products such as linear actuators where improved performance, lower cost, smaller form factors and added features drive new product developments, system requirements can

Diaphragm pump dodges downtime

feeds.penton.com | Sep 17, 2007

It's estimated that 60% of the total ownership costs of a diaphragm pump are due to downtime, and two of the leading causes are freezing and stalling.

The advantage of diaphragm pumps compared to piston pumps is that they generate markedly less shearing, which can destroy pigment and binder structures. As some paints (e.g. UV paints) are very sensitive to shearing, diaphragm pumps are ideally suited for these materials because potentially damaging shear forces are virtually nonexistent. Diaphragm pumps can be subdivided into low pressure double diaphragm pumps, low pressure double dia phragm ratio pumps and high pressure double diaphragm pumps. These three variants are described below. LOW PRESSURE DOUBLE MEMBRANE PUMPS (ZIP SERIES) The double diaphragm pumps of the Zip series operate at a 1 :1 ratio. This means that the material outlet pressure is equal to the air inlet pressure. The volumetric flow reaches 1 82 l/min. Thus these pumps are primarily suited as transfer pumps, which means they are used to transport material in large paint supply systems. Double diaphragm pumps are id
