Cleanroom Cleaning Services

Cleanroom - intro

Yargay MCI’s Cleanroom Services cover the needs of new and existing cleanrooms. So, whether you need a Post Construction Cleaning for a newly constructed cleanroom or Technical Cleaning to the one you are already running.

Our Cleanroom Cleaning Services help improved product quality and yields related to a contaminated environment – and best of all, you have peace of mind knowing that our Specialists are specifically trained for your critical environment.

MOBILE UV-C LIGHT DISINFECTION SERVICE (ADD-ON)

The awareness to apply regular disinfectant has seemingly increased in the midst of the recent Covid-19 pandemic. Yargay is always at the forefront of new technology and implementation. We now introduce the latest mobile UV-C Light Disinfection Machine to disinfect your cleanroom after every deep cleaning work, as an added precaution to disinfect their cleanroom environment.

These Mobile UV-C Light Disinfection machine are built with a lamp module emitting powerful ultraviolet-C(UV-C) light. This light help decontaminate the cleanroom environment by tearing apart strands of viruses DNA .

As UV-C light kills up to 99% of bacteria and has been clinically proven to eliminate viruses. Your cleanroom environment will be kept safe and healthy for your team to work safely with the help of this machine.

IS CLEANROOM CLEANING NECESSARY?

Particulates are deposited directly onto surfaces such as floors, walls, work surfaces, and machinery. They may not affect products at the time they are deposited, but over time they pose an increasing threat to your products by causing physical disturbance and eventual breakdown. Even with modern technology and stringent procedures to control particulate contamination, you are still only controlling a portion of cleanroom dangers.

Cross Contamination is the most significant cause of downtime and loss of yield within a cleanroom environment. Semiconductors, Pharmaceuticals, Manufacturing Centers and Testing Facilities all require different operation methods and designs.

Cleanroom - Is cleanroom cleaning necessary

To reduce a Clean Room's risks it is imperative that an effective cleaning program be implemented and maintained consistently throughout the life of the cleanroom.

Cleanroom - common janitorial

Yargay MCI can custom fit a plan for cleaning and maintenance that will compliment your company’s work flow.

Cleanrooms consist of specialised materials, chemicals, equipment and protocol unique to each facility. As the front-line defense in protecting the customer’s investment, it requires trained personnel, application-specific cleaning tools & materials, a well-designed cleaning methodology, a verification program and a commitment to ensure that cleanroom maintenance demands, receive the highest priority from all involved. These services should also be applied to laboratories and other critical environments.

Common janitorial cleaners are not trained or insured to clean these technical environments according to standards and can cause downtime.

That’s why Yargay MCI makes a substantial commitment to on-going training. Our Specialists are permanent employees that are classroom educated with hands-on experience at cleanroom site training facility. Our proprietary training programs are in accordance to IEST’s (Institute of Environmental Sciences Technology) standards which include; cleanroom protocol, cleanroom cleaning processes and methods, workplace and general safety awareness and other specialised disciplines.

Cleanroom maintenance is a very niche market & Yargay MCI has the expertise in capturing a handful of market share as well as to develop new customer base. We are a Senior Member of IEST and our cleanroom housekeeping and cleaning procedures are in accordance to the IEST’s recommended standard.

Our stringent testing procedures and highly trained personnel are key components in eliminating all possible threats to your cleanroom yield.

CLEANROOM DANGERS

Any material, substance, particle, chemical, or other undesirable substance that is unwanted that can taint, pollute, defile, make impure or unclean, or adversely effect the process or product. Contamination can take many forms such as: particulate, chemicals (including gases), electro-static discharge, viables (bacteria, molds, etc.), and other forms.

Particles are measured in microns. If you were to slice a 1-inch cube into 25,400 equal pieces, each slice would be 1 micron thick. (So thin that you could not see it.)

Since cleanroom facilities contain invisible particles that can cause defects, we need to have a way to determine their sizes and possible sources. These particles cannot be seen with the naked eye and yet may cause serious loss to our client and to their ability to manufacture devices without defects. We measure the amount of particles in the air with a device known as a particle counter. This helps us to determine when to perform or restrict certain activities.

Typical Pollutant Sizes That Cause Down Time

Bacteria

.01 to 1.0 Microns

Dust

1.0 to 10 Microns

Mold

1.0 to 10 Microns

Hair

10 to 100 Microns

Pollen

10 to 100 Microns

Following are some common sources of contamination. This list in by no means exhaustive, but it gives you and idea of the types of things to be aware of when you are looking for the source of contamination.

Hair

Skin Flakes

Saliva

Make-Up

Lotions

Perfumes

Coughing / Sneezing

Excessive Movement

Perspiration

Wood

Paper

Cardboard

Tobacco Products

Gum, Cough Drops

Packing Materials

Duct Tape

Dirty Clothing

Chemicals

Caulks and Paints

Aerosols

Ions (Rust)

Permanent Markers

Non-Cleanroom pens

Smoke

Thinners /Solvents

Food and Drink

 

To combat the tremendous amount of particulate released by the human body, cleanroom personnel are asked to wear special garments that are restrictive and may be uncomfortable if the working conditions (temperature, humidity) are not carefully controlled.

People are dressed in booties, gloves, helmets, hoods and special facemasks that are not part of a normal experience. You are also asked to move slowly, to clean up dirt you cannot see, and to follow practices and procedures that may not immediately make sense.

The approach to cleanroom is designed in steps so as to ensure that every effort has been made not to introduce contaminants into the cleanroom.

THE HUMAN FACTOR

“Humans are walking, breathing, waste pits from a microbiological perspective and there is no indication we are going to evolve into anything cleaner.”

Human dust combined with sebum will tenaciously adhere to and contaminate surfaces, creating contamination problems that are simultaneously bacterial, chemical and particulate.

There is an additional complicating factor – normal human activity. Humans breathe, sneeze, cough, talk and move around. Body and breath temperatures cause heat turbulence in addition to air turbulence.

People slough off huge numbers of particles a half micron and larger and these are propelled around by air and body movement. Some examples of how many 0.5 micron and larger particles can be released by simple movement are shown below. Vast amounts of contamination need to be controlled in a cleanroom environment.

Activity

Particles Release

Seated

100,000 particles per minute

Moving 2 miles per hour

5 million particles per minute

Moving 3.5 miles per hour

7.5 million particles per minute

Moving 5 miles per hour

10 million particles per minute

Contaminants, Sources and Potential Damage

Type

Source

Damage Potential

Metallics

Vacuum cleaner motor brushes, wear of A/C units, printer wear, raised floor and grid.

Electrically conductive, magnetically attracted to micro-circuits.

Carbonaceous

Automobile exhaust, tobacco smoke, printer toner, oxidized organic material, paper dust.

Moisture absorbent, electrically conductive, combustible.

Synthetic Fibrous Particulate

Operator clothing, carpeted floor tiles.
