Ward 960-cb etchtek acid solvent bath temp controller
This listing is for a temperature control / timer.
* Make: Ward Technologies Inc
Ward Technologies, Inc. has designed a complete line of Constant Temperature Controlled Acid/Solvent Baths and has a full line of Microprocessor Based Controllers.
Our Constant Temperature Baths are designed to be a contaminant free, rapid heating units suitable for use with most acid based chemistries used in wet-etch applications. They are also compatible with many solvents used in semiconductor processing.
Ward Technologies has a complete repair facility staffed and qualified, industry trained technicians. This facility is available for the repair and refurbishment of all constant temperature baths of any manufacturer.
Ward Technologies' Controllers are state of the art, fully programmable and are constructed of high-grade materials for durability and accurate temperature regulation. Membrane switches are incorporated in the faceplates to allow user setup and adjustments, and they are suitable for use in all the fabrication processes of the semiconductor industry.
MODEL 960 SERIES TEMPERATURE CONTROLLERS - Etchtek Temperature Controller Units - Etchtek 960-C/CP Controller/Timer
Twelve discrete LEDs are utilized to indicate system and display status as well as annunciate various alarms. A 12 key membrane switch is incorporated in the facepanel to allow for user setup and adjustment of the system. Plus full timer control.
Two numeric displays are utilized to allow the viewing of both the process temperature and the timer simultaneously. Additionally, each of the displays has multiple diagnostic and setup functions and setup functions that may be activated by the keyboard or by the Microprocessor during various setup and alarm conditions.
