White Knight Fluid Handling is pleased to announce the release of the much-anticipated PEM050 electronic metering pump for chemical replenishing, blending, dosing, and spiking applications. The PEM050 dispense up to 50 ml of high-purity chemical with ±0.01% repeatability at high pressures (60-80 psi). They feature PTFE fluid paths and fully supported rolling diaphragms to…Details
This report compares pressure and flow pulsations from a White Knight closed-loop control system and Levitronix system and evaluates their effect on the retention efficiency of a membrane filter. The White Knight system featured a PSA060 bellows pump; the Levitronix system used a BPS-4 centrifugal pump.Details
Nison Custom Designed Replacement Quartz In-line Heater Imtec today fabricated its 30th unit of a specially configured inline heater designed to easily integrate into a Nison Hot Phos chemical module. This replaces a heater that is often difficult and expensive to acquire. Mark West of Imtec said “In today’s competitive manufacturing environment, extending the life…Details
A White Knight PXASD060 bellows pump and Levitronix BPS600 centrifugal pump were run simultaneously in identical recirculation systems. The bath temperature was recorded eight hours. White Knight’s pump maintained a stable fluid temperature. The centrifugal pump heated the fluid bath significantly.Details
Solid State Technology and SEMI have selected the Closed-Loop Control System as a 2013 Best of West Award finalist. The closed-loop system provides complete control of high-purity chemical processes and delivery systems with customizable feedback capability to maintain optimum system performance. It is designed to support process tools that require a set flow or pressure at the point of use.Details
The Closed-Loop Controller (CPC-1) automatically adjusts to maintain a set pressure or flow rate in high purity, closed-loop chemical pumping systems to compensate for variables in wafer processes, such as opening/closing chamber valves or clogging filters. The controlled closed-loop system improves process repeatability, increases chip yields, and simplifies automation to save customers time and resources.…Details
White Knight’s Cycle Rate Translator (CPT-1) enables pump swap-outs in existing tools. The CPT-1 operates White Knight pumps at their optimal cycle rate and communicates a scaled operational cycle rate to match that expected by the tool. It also manages cycle rate errors and eliminates steady-state cycle rate alarms.
DBA and DBH Series in-line and top-mount pulse dampeners augment the capabilities of White Knight high purity pumps. They reduce pulsation in fluid systems to improve flow control, increase batch yields, protect filters, fittings and pipes, and minimize downtime for system repairs. DBA and DBH Series dampeners operate in temperatures up to 100°C (212°F) and 145°C (293°F), respectively.Details
