CLEAN ROOM FOR SEMI-CONDUCTOR INDUSTRY APPLICATION
Due to the sensitive nature of their products, clean room
facilities for microelectronic and semiconductor applications
require stringent environmental controls. These clean rooms
also house extremely precise and expensive equipment such as
photolithography, etching, cleaning, doping, and dicing
machines.
Hence,
any
deficiencies
in
the
cleanliness
specifications can affect the entire production process. Other
common issues in microelectronic & semiconductor clean room
conception and design are the maximizing of space while also
enabling future reconfiguration. For all these reasons, a
modular clean room system is often the optimal solution.
The kind of clean room application is one of its most important
spaces since this is where the environment must be controlled
to eliminate all dust, dampened against vibration, kept within
narrow bands of temperature and humidity. Microelectronic &
semiconductor clean rooms range from Class 100 to Class 100 000
depending on the processes taking place within the facility.
For some applications, the cleanroom must also comply with
specifications associated with electrostatic charges or
discharges (ESD compatibility). Electrostatics can cause
product contamination, product damage from electrostatic
discharge (ESD) and production equipment malfunction caused by
ESD-generated electromagnetic interference (EMI).
Special painted PPGI panels are ESD compliant. Controlling
temperature and humidity is critical to minimize static
electricity. This type of clean room can use high precision
humidity (up to ±2%) and temperature (up to ±0.25°C)
control systems
CLEAN ROOM FOR MEDICAL DEVICE INDUSTRY APPLICATION
There are important differences between clean rooms for
medical device manufacturing purposes and those for the
manufacturing of optical products, semiconductors, or any
other electronic devices not intended to penetrate the skin
or interact with the body. Medical device clean rooms must be
designed to control both airborne particles, which are the
nemesis of hard drives and microchips, as well as
microorganisms that must be controlled to prevent the risk of
contamination and thus ensure patient safety. For example, the
clean room in which medical OEMs produce spinal implant
technologies must display extremely low bio burden rates, as
well as a restricted amount of airborne particles.
Faced with an increasingly regulated industry, some medical
device manufacturers are forced to upgrade or build a new
clean room to comply with the new standards. Initially driven
by the semiconductor industry, cleanliness standards are now
starting to be designed specifically for the medical device
industry. The type of devices being manufactured will determine
the cleanliness level the clean room must meet. For example,
complex Class III medical devices face some of the most
stringent quality requirements in the industry.
Clean Room For Pharmaceutical Industry
Pharmaceutical production ： Biopharmaceutical clean room
pollution control: pollution source control, dissemination
process control, cross-contamination control.
Different cleanliness requirements corresponding to the
process are proposed for the pharmaceutical production
environment. For the preparation of raw materials,powders,
injections, tablets, large infusion production, filling and
other processes, cleanliness standards for clean areas and
control areas have been established.
The key technology of clean room medicine is mainly to control
dust and microorganisms. As a pollutant, microorganisms are
the most important environmental control of clean room. The
equipment and pipelines in the clean area of the pharmaceutical
factory can directly pollute the medicine without affecting
the cleanliness test. Therefore, we say: GMP requires air
purification technology, and air purification technology does
not mean that the cleanliness level is not applicable.

properties of suspended particles.
