For many types of manufacturing services, a highly sanitized and isolated workspace is key. To prevent contamination and poor production practices, sealed clean rooms with varying degrees of quarantine are necessary. At MultiSource Manufacturing LLC, we ensure the protection of semiconductor components and assemblies during fabrication with our ISO Class 3 (FED STD 209E Class 1) clean room.
The certification of our clean room to a Class 3 is critical for all our semiconductor services and many medical component and assembly production. When you choose MultiSource for your clean room-required contract manufacturing services, you can trust our facilities to protect every part of your product from start to finish.
Each clean room across the industrial world needs to meet highly specific requirements in order to qualify for ISO (globally) or Federal Standard (in the U.S.). A large part of meeting these specifications has to do with the airflow.
Airflow in a clean room is a critical part of what makes it so clean. Put simply, all clean rooms need a down-and-out flow of air. The ventilation systems are installed in the ceiling and push airflow directly downward while other vents pull the flow outward, removing air continuously from the isolated room. This also continuously removes any particulates, bacteria, and other contamination from the room as it’s passed through with the air.
There are two main types of clean rooms that the majority of contract manufacturers use for any industrial processes that require extreme isolation from contaminants. These include:
- Single Pass: These simple-type clean rooms push the airflow down-and-out continuously. This means there is new air constantly introduced to the room through high-grade filters in the top vents and that air is then removed from the room entirely. These clean rooms can be used for manufacturing processes that don’t need climate-control options, such as temperature and humidity.
- Recirculating: For manufacturing processes that need exacting humidity and temperature control as well as high air filtration, more complex clean rooms that use recirculating systems are vital. Recirculating systems have an additional wall containing the interior room. This passageway around the room seals airflow and the air pushed down-and-out of the interior room is forced back upwards to the top of the room and re-filtered through the top vents. This ensures continued filtration and exposure to the same allotment of air for as long as the room and exterior passage is sealed.
For semiconductor and medical device manufacturing, single pass clean rooms can be effective, but a recirculating room is recommended for true quality in production. Our Class 3 clean room uses a recirculating airflow for excellence and safety in all our manufacturing processes that require zero-contaminant exposure.
