Surface Quality Monitors表面质量检测系统

Surface Quality Monitor model SQM200W

PET manufactures and markets non-destructive, non-contact surface contamination and thin film detection models and automated systems (surface quality monitoring system) capable of detecting thin layer contamination, thin films and coating down to the Angstrom level. These systems represent a major breakthrough by providing, for the first time, a quantitative measure of surface cleanliness. As surface cleanliness verification instruments, in a part cleaning environment, these products are capable of validating the cleaning quality of all the part cleaning equipment available in the market. Any of SQM model series is capable of verifying metal contamination; monitoring absence/presence of organic and/or inorganic on virtually on surfaces of all metals. They are, price/performance, the most sufficient product available for testing surface of metals for surface cleanliness. These systems operate in an ambient environment, require no sample preparation or deposit of any agents on the surface. In any parts cleaning environment where the quality and efficiency of part cleaning equipment for removal of surface contamination is highly desired, these systems provide a scientific solution by quantitatively measuring the surface cleanliness. The SQM series has the sensitivity and operational simplicity required to provide fast and cost effective surface evaluation for all metals.

SURFACE QUALITY MONITORS MODELS

SQM200W
A single channel system for measuring surface cleanliness or monitoring absence/presence of organic/inorganic thin films or measuring the relative thickness of very thin films. System features include upper and lower acceptance limits, go/no go indicators and analog signal output.

SQM300W
A single channel system for measuring surface cleanliness or monitoring absence/presence of organic/inorganic thin films or measuring the relative thickness of very thin films. System features include upper and lower acceptance limits, go/no go indicators, process control chart, automatic data storage, inspection procedure information stored for unlimited different parts/components and analog signal output.

SQM500W
An integrated turn-key scanning, data acquisition and 3-D color graphics system for scanning a flat surface to help make NON-VISIBLE contaminants/coatings become VISIBLE through a color mapping technique. The system includes a SQM200W system with motor driven and software controlled X-Y scanning table with 6” x 6”. Stages with larger travel are optional. This system is a powerful tool for studying and monitoring surface chemistry variations.

SQM600W
An integrated turn-key scanning, data acquisition and 3-D color graphics system for scanning a flat surface to help make NON-VISIBLE contaminants/coatings become VISIBLE through a color mapping technique. The system includes a SQM200W system with motor driven and software controlled rotary scanning table and a linear slide. This system is a powerful tool for studying and monitoring surface chemistry variations.

OSEE APPLICATIONS

SURFACE CLEANLINESS MONITORING & VERIFICATION

• Detect both organic and inorganic contamination.

• Quantitatively establish the level of cleanliness achieved by the existing cleaning process.

• Establish an acceptable range of quantitative measurement for surface cleanliness.

• Evaluate the effectiveness of new and potential cleaning processes.

• Optimize cleaning processes by measuring changes in the surface cleanliness level as a result of changes made to cleaning processes.

• Monitor cleaning processes on an ongoing basis to assure that an acceptable level of cleanliness is achieved.

• Prevent product quality problems due to poor surface cleanliness.

• Optimize and monitor the rinse cycle to insure that parts have been properly rinsed.

• Replace water break and other qualitative tests with a quantitative measurement of surface cleanliness.

LUBRICANTS, COATINGS OR THIN FILMS

• Detect absence or presence of invisible, clear thin films, coatings or lubricants on virtually any surface.

• Monitor the relative thickness of very thin films, coatings or lubricants, both off-line and on-line.

CHANGES IN CHEMICAL STATE OF ANY SURFACE

• Detect micro changes in the chemical state of any surface.

• Monitor parts or witness panels for deposition of Airborne Molecular Contamination (AMC's)

• Monitor for deposition of contaminants due to out gassing of storage containers or packing materials.

• Indirect monitoring of blind holes and small chambers for contamination.

BENEFITS

• Stop over-cleaning and reduce cleaning agent use.

• Reduce rejects & reworks.

• Improve coating & paint adhesion.

• Improve bond strength.

• Increase productivity by optimizing cleaning processes and maximize environmental protection.
