Air Filtration Reduces Airborne Molecular Contamination Risk for Microelectronics Production
Fine particulate and Airborne Molecular Contamination (AMC) control is crucial for high-yield, low-reject semiconductor, microelectronics and digital technology manufacturing industries. Dust and other microparticles can lead to damaged and rejected inventory, contaminate processes and short circuit the microprocessors, chips and wafers.Sources of AMC include:
- chemical offgassing
- exhaust fumes from other industries and processes
- vehicle exhaust fumes
- seasonal factors
- Leaks or spills from solvents
- Organic contamination such as moisture and dust
Failures due to AMC are classified as:
- Mechanical effects - obstruction of cooling airflow, interference of moving or optical parts, and deformation of surfaces.
- Chemical effects - corrosion of electrical components, due to dust comprised of sulfur and chlorine bearing salts.
- Electrical effects - impedance changes and electronic circuit conductor bridging
Creating a cleanroom environment helps to mitigate those failures. HEPA filters, dual filtration system and high efficiency media, are all recommended in constructing the clean environment facility. Prefilters and secondary filters can help eliminate airborne particulates as well as the noxious odors that are given off by the used chemicals.
Cleanroom Filtration Standards
AAF Flanders engineers are active in standardization committees in the USA and Europe. We play an important role in establishing new standards and recommending practices for cleanroom applications. As an example, our engineers were key contributors in developing and writing Institute of Environmental Sciences and Technology Recommended Practices. This professional competence is reflected in the design, manufacture, and testing of each cleanroom filtration solution we produce. The result is cleanroom filters engineered and assembled to give you the particulate removal you require, while delivering energy efficiencies and savings to your bottom line.
Optimize Your Filtration and Improve Your Environment
A thorough air filter audit of your HVAC Systems is the first step that AAF Flanders takes, in order to provide you professional guidance and analysis for cost savings and liability reduction. By conducting this audit, we strive to understand your current state and your complete air filtration needs, applications, and goals for total air quality. This customized air filtration survey costs you nothing and could give you significant benefits by helping you save money, reduce risk, and save time.
Contact your AAF Flanders representative to schedule an audit and to find out how the insights from intelligent data tools, including TCO Diagnostic® and Sensor360®, can improve operational outcomes and save you time and money.
