In any manufacturing process, contaminants should be avoided. Certain manufacturing processes, however, require an avoidance of contaminants far more stringent than others. Semiconductors and semiconductor assembly fabrication, for example, cannot have exposure to common air contaminants.
To protect manufacturing processes like these and the materials involved, fabricators make use of clean rooms with varying levels of contaminant-free standards. MultiSource Manufacturing, LLC provides contract fabrication services for the semiconductor and medical industry, and because of this, our facilities have in-house Class 3/1000 clean room capabilities.
With our clean room capabilities at our Burnsville, MN location, the MultiSource network is able to provide the contaminant-free workspace our engineers and technicians need to perform operations on semiconductor components and full assemblies as well as a range of advanced medical devices.
Clean Room Principles
Clean rooms are designed to prevent the introduction of contaminants in a varying range of sizes to the manufacturing process, as well as other potentially damaging factors such as humidity, pressure, and temperature. This prevention makes use of High Efficiency Particulate Air (HEPA) filters and a sealed “bubble” of a room. All the air in a clean room is passed through HEPA filters or recycled through them. The level of HEPA filtration determines the categorizing of a clean room. These categories are determined by ISO standards rating from ISO 9 (standard city air quality) to ISO 1 (less than 10 particles measuring 1µm per cubic meter).
Our Clean Room
The MultiSource clean room is rated as ISO Class 3 (Class 1 rated FED STD 209E). This means a maximum of 1,000 1µm particles per cubic meter are left unfiltered. It is one of the highest quality clean rooms utilized for semiconductor and medical parts manufacturing. Our clean room uses advanced HEPA filters to eliminate the potential of any damaging infiltrates during the manufacturing and assembly process.
Like the rest of the outdoor and common indoor air, humans carry contaminating particulates such as dander, dirt, skin cells, pollen, bacteria, and mold spores. The technicians who work in our clean rooms are required to wear protective equipment to prevent any potentials of component damage in the manufacturing process. This protective equipment includes full-body suits, gloves, boots, and masks/respirators.
Air Flow Concepts
Acting similarly to a car air flow system set to recycle, clean rooms have a specific movement of air throughout their interior. Our clean room uses laminar air flow which pushes a continual stream of filtered air from ducts in the ceiling. This ensures any potential contaminants are pushed into the air filters immediately, instead of drifting through the clean room on an uneven current.
Our clean room capabilities give our engineers and technicians the contaminant-free space they need for specialized manufacturing processes. To learn more, contact MultiSource Manufacturing, LLC at (952) 456-5500, request more information, or request a quote to get started with us today.
