Component Cleanliness Testing for Liquid Systems
Cleanliness testing for liquid systems can help ensure components meet the standards aimed for.
Contamination from fluid handling components can eventually reach the processing environment either in the form of solid particulates or, through chemical reaction, as a form of ionic contamination…
OLED N2 Box Particle Monitoring Solutions
The Flat Panel Display manufacturing industry is evolving rapidly with growth driven by mobile devices and resolution improvements. Most display manufacturers are investing in Organic Light Emitting Diode (OLED) technology which offers improvements in color fidelity, contrast, and power consumption over legacy TFT-LCD platforms. Compared with TFT-LCD, the OLED process is more sensitive to micro contamination, including particles, electrostatic discharge (ESD), airborne molecular contamination (AMC), volatile organic compounds (VOC), and even H2O molecules….
Particle Counter Laser Life Factors
Particle counters use lasers which provide intense light to count very small particles. All lasers have a finite lifetime, but that lifetime can be extended or shortened based on how the laser is used. Your cost of ownership will decrease if the laser lasts longer. Particle Measuring Systems was the first company to build a laser-based particle counter, and we have the best understanding of how to extend laser life.
The three major factors that determine laser life are:
1. the design and manufacture of the laser itself
2 the operating temperature of the laser
3. the operating power that is used versus the rated power of the device
