III. The importance of clean room equipment

Clean room equipment, utensils and utensils are a huge factor that directly affects the quality of clean rooms in research as well as production. Can include the name of equipment such as clothing, hats, masks, glasses, gloves, thick, sandals, writing paper, manipulation tools, tables, chairs, ... If not the right choice Standard products for clean rooms are very likely to have serious consequences on the product.

IV. The need for a clean room

Companies producing and assembling electronic components and circuit boards often encounter problems of product failure due to the presence of dust particles in the air, so clean rooms are especially focused on dust-free. Since then, replicated systems have developed, control systems, filtration systems, and accordingly protective clothing products to prevent room dust and dirt.

Today, clean rooms are used for many fields such as medical, material science and technology, electronic components, physics, chemistry, biology, precision engineering, pharmacy, food, semiconductors...

V. Standard clean room
The first standard of a clean room is the content of dust, that is, the content of dust particles suspended in the air is controlled. If we compare it figuratively, the diameter of a human hair is about 100um, the dust in the room can be from 0.5 to 50um in diameter.
5.1 An important international standard for clean rooms
· US Federal Std 209E 1992
· EEC cGMP 1989
· France AFNOR 1989
· German VDI 2083 1990
· British BS 5295 1989
· Japan JIS B 9920 1989
· ISO EN 14611-1 1999
· Australia AS 1386 - 1989

Clean room standards were first introduced in 1963 in the United States, and have now become common standards for the world. These are standards that specify the amount of particulate matter per unit volume of air. It is divided into levels of dust size and type of room determined by the number of particles larger than 0.5 um in a volume of 1 cubic foot of air in the room.

5.2. Federal Standard 209 Standard, 1963

This standard was first defined in 1963 as 209 and then continuously improved, perfecting versions 209A, 209B until 209E.

Federal Standard 209 Standard, 1963

5.3. Federal Standard 209 E standard in 1992
This standard defines the content of suspended dust in air in standard cubic meters. The clean room classification is determined on a log scale of dust content with a diameter greater than 0.5 / mum.

Federal Standard 209 E standard in 1992

5.4. ISO 14644-1 standard
The International Standards Organization has set standards for clean rooms of international standards. The ISO 14644-1 standard, released in 1999, is called "Air Cleanness Classification".

ISO 14644-1 standard

In particular, the level of air pollution in the room depends on the dust particles generated in the room activities, not just the fixed number in the room. Therefore, in room standards always require continuous cleaning systems, which specify the number of people and activities that are allowed to be performed in the room.

There are also different regulations on the peculiarities and characteristics of each industry.

For the electronics industry in Vietnam, clean room is still a new concept and has not been widely applied. However, in fact today, there are many factories building clean rooms to meet the strict standards of products for business partners in the markets of Japan, Korea, China, USA and other countries. in Europe ...

VI. Application of clean room
6.1 Application of clean room for food storage

Foods such as cakes, candies, canned foods, dried foods or fresh foods must be stored in a clean and safe space. Because if the amount of microorganisms is high and the dust content is high, it will cause the food to be contaminated, affecting the fermentation process, leading to faster spoilage. Therefore, preserving food is a closed process, in order to limit the development of microbiological processes to increase the shelf life of food.
