Highlights

APMON II sensor

• Sensor can operate stand alone. Data analyse and user interface through AWS cloud server.
• Several sensors (max 16) at various locations can be observed in one user interface.
• Realtime screens with actual particle deposition rate levels.
• Differential and cumulative particle size distribution.
• Standards ISO 14644-17, IEST 1246E
• Insights helps user to set limits and to evaluate cleanroom performance.
• Automatic Report function
• Export of data.

APMON 2 system

• Particles > 15 µm
• Particle area coverage > 0.02 ppm
• Measurement area 50 cm²
• Sample times 4, 5, 6, 10 or 15 minutes
• Ethernet or Wi-Fi connection

The APMON ^II sensor sends holographic particle images by ethernet or Wi-Fi to the AWS data platform on the internet, where these are analysed. The APMON 2 provides information on particle deposition rate, likelihood of product or process contamination, particle size distribution, particle area coverage and alarm .

Data of one or more particle deposition sensors from one or more locations are collected on one platform which can be accessed by various authorised employees: operator,  production manager, quality engineer, division manager etc. who can select a personal dashboard. Other data sources can be added to the platform.

Automatic reporting and application analysis will increase the insights on the effectiveness of the applied contamination control measures and provide improvement recommendations.

Description

How does it work?

APMON sensors collect 24/7 real-time data on the use of your clean controlled environment. They provide data on the deposition of airborne macro-particles. Light scattering airborne particle counters do not predict which particles can deposit onto surfaces. APMON II counts and sizes particles larger than 15 micrometers up to fibres of a millimeter and the moment these were deposited.

Particle deposition data show when and how much your product or process is at risk, the performance of your cleanroom and what can be done to improve the operational quality and to reduce risks.

Through AWS and a secured data transfer protocol, the data from different locations can be viewed simultaneously. Multiple locations and sensors can be linked together. This makes it easy to monitor and benchmark different processes and production locations of your company worldwide.

APMON II can be used in clean environments, cleanrooms and clean zones with personnel where particle and/or microbial contamination are important. Typical cleanroom classes are ISO 5, 6, 7 and 8 in operation. In these environments the way a cleanroom is used has impact on particle deposition rate.

In mini-environments and in process equipment where the air cleanliness is lower than ISO 4 the particle deposition rate is in most cases too low to determine the particle deposition rate within 24 hours.

Potential industries are: automotive (combustion/electrical motors, batteries, gear boxes, sensors and actuators), aerospace, assembly of electronics, displays, optics, MEMS and medical devices, clean machines for semiconductor and UHV, healthcare, hospitals, preparation of medical devices and instruments, etc.

Measures to control surface cleanliness are:

• Limit introduction of particles in the clean environment
• Avoid unnecessary surfaces inside the clean environment
• Ventilate the clean environment with a sufficient volume rate of filtered air
• Clean all surfaces frequently in a systematic manner, check cleaning efficiency using the SUMON.
• Monitor the surface cleanliness using the SUMON
• Monitor the resulting particle deposition rate using the SUMON or for real-time monitoring the APMON
