JST’s Quick Dump Rinse supplies deionized (DI) water from the bottom of the bath through ports that direct the flow up and across the product’s surface. This upward flow lifts the particles and chemicals away from the product and over the four sided overflow weir. After the short overflow cycle, the bottom dump door opens and quickly dumps the rinse water. At the same time, top mounted sprays keep the product wet with fresh, clean DI water during the dumping process. The quick dump rinse is followed by a high flow cascade rinse to ensure all chemical and particulate is removed.

A touch screen PLC offers flexibility in creating specific rinsing routines and has the ability to set the number of rinse and dump cycles. Timers are included for programming high flow cascade cycle times. An automatic self-cleaning cycle flushes and purges the quick dump plumbing valves and DI water manifold to eliminate bacterial growth.

Quartz Recirculating System for critical cleans and high temperature applications.

JST’s Megasonic Baths provide a high level of cleaning performance by applying high frequency energy (greater than 700 kHz) to effectively remove submicron particles via acoustic cavitation. The high frequency energy and cavitation reduces the boundary layer between the fluid and the surface of the part resulting in fine particle removal. JST’s baths are designed to provide continuous megasonic energy across the full width and depth for continuous full coverage.

Elevated temperature can also help lower the chemistry’s surface tension and further improve substrate cleaning. JST offers ambient static megasonic baths and megasonic Quick Dump Rinsers giving customers the ability to fine tune their processes.

Utilized for metal lift off and removal of heavy particles that have a tendency to fall to the bottom of the tank.

JST’s heated downflow baths are designed for metal lift off and removal of heavy particles that have a tendency to fall to the bottom of the tank. Filtered and heated solvent chemistry flows directly onto the submersed parts lifting the containminants and flowing them down the bottom of the tank and out the bath drain. This downflow action eliminates the possiblity of sheeting films redepositing back onto the product. In a typical overflow bath, chemistry is introduced into the tank via the bottom and flows over the product and out the top into the overflow weir leaving heavier films to circulate within the body of the bath. With JST’s downflow design the particles are pulled out of the tank and captured in a filter trap.

A 10 inch inline filter housing accepts a standard 10 inch dual o-ring filter cartridge allowing users to install the type of filter cartridge they need depending on chemistry pH and particle removal size required. For applications that require reclaim, a removable filter trap is available.

The heating elements are bonded to the outer walls, insulated and contained with an outer shroud. The heating element in the double wall housing is N2 purged. Inline heaters are recommended for large, high temperature baths that require a fast heat up time or higher processing temperatures.

 Heated Filtered baths continuously filter process chemicals in a laminar flow direction.

JST’s Heated Filtered bath continuously filters process chemicals in a laminar flow direction from the bottom of the bath upward over a four sided weir. The bath is design to filter sub-micron particles and reduce chemical consumption.

A 12 inch inline filter housing accepts a standard 10 inch dual o-ring filter cartridge allowing users to install the type of filter cartridge they need depending on chemistry pH and particle removal size required.

Baths are available in 316L stainless steel or quartz with serrated overflow edges for uniformity.

Maintains accurate temperature control and particle removal.

JST’s Constant Temperature Bath maintains accurate temperature control and particle removal. The recirculated chemistry flow enters the bottom of the process bath, directed in a laminar flow up to a four sided overflow weir then returned back through a pump and filter prior to returning to the process bath.The bath is design to filter sub-micron particles and reduce chemical consumption.

The chemistry temperature is controlled by a remote heat/chiller unit using closed loop coils that transfer and maintain the temperature in the bath.

A Microprocessor PID programmableTemperature Timer controls the process parameters and process times. A RTD probe monitors the process temperature, high and low temperature set points and the alarms. A liquid level monitors detects the liquid level in the tank and has an audio alarm and interlock to shut off the pump at low liquid level.

Designed to maintain uniform temperature for processing while meeting NEC and SEMI standards for safety.

JST’s Static Heated Baths are designed to maintain uniform temperature for processing while meeting NEC and SEMI standards for safety. Quartz and 316L grade stainless steel tanks have the heating element bonded to the outer walls, insulated and contained with an outer shroud. The heating element in the double wall housing is N2 purged and monitored for additional safety for solvent applications. PVDF and Teflon tanks have submersible Teflon coated heaters resting in the bottom of the tank.

A proportional controller using a Type J RTD temperature probe controls the bath temperature. The controller has a programmable temperature and timer. An audio alarm sounds if the bath goes out of the specified operating temperature. In an over temperature condition the controller will turn off the heaters. A heating element snap switch protects an over temperature condition in case the controller or probe fails. A liquid level detection monitors the chemistry level in the bath to keep a safe operating level.

This bath is designed to filter sub-micron particles and reduce chemical consumption.

 

JST’s utility sinks are available in all sizes and materials. Goosenecks can be configured with remote momentary switch, manual valve as shown at right or with a foot pedal control.

Removable lids can be added to increase your workspace when the sink is not in use.
