AST has long had a core business in plasma processing. Surface treatments are generally developed on an individual basis with AST's technical staff working closely with customers. These treatments are proprietary and are protected trade secrets. In order to support this technology more fully, AST offers a quality line of plasma reactors.

The critical factors for effective plasma treatment are uniformity, consistency and process development. Backed by the company's superior expertise in surface modification, coating and contact angle measuring technologies, AST/Plasma Science group provides the best knowledge to work with our customers for critical process development.
Further more, all our systems are equipped with the following features to ensure treatment consistency and effectiveness such as:

• Patented electrode configuration - proven maximum uniformity

(US Patent no. 4,887,005/5,190,703/5,228963/5,468,560/5,733,511)
• Microprocessor touch screen controller - easy and precise operation control
• Primary plasma operation - most effective plasma exposure to all parts
• MFC gas input and mixing - precise, reproducible mixing and distribution
• RF auto matching network - reliable and efficient gas plasma generation
• Turnkey vacuum system - readily integrated for the most efficient operation
