Cleanliness Test ISO Class 7 Cleanroom Layout Plan
Cleanroom layout planning can be customized according to various customer requirements.
Cleanroom overall planning and layout with zero dust cleanliness
Air Shower Room, Transfer Suit, Transparent Glass Window
Purification Structure, Purification System, Power Distribution System
The division of various functional areas, such as: sample preparation cleaning area, particle analysis area, document storage area, etc.
Cleanroom cleanliness meets the requirements of ISO 14644-2015, GB 50073-2001, and other standards.
Cleanliness Classrooms for Dust-Free Laboratory Construction are primarily categorized into:
Purification structure section
Purification System Components
Power distribution section
Cleanliness Class 100 (ISO 5) cleanroom is mainly divided into the following areas:
Employee Changing Room Area
Cleaning Sample Preparation Area
Sample Analysis Area (including weighing and particle size analysis)
Sample Transfer Area
Storage Area for Cleaning Liquids
Document Storage Area
Customers provide 220V power on-site, and regular water supply is sufficient.
The cleanroom maintains its original set requirements for cleanliness, temperature, humidity, and pressure, regardless of changes in the external air conditions.
The primary function of a cleanroom is to control the cleanliness, temperature, and humidity of the air the product (such as silicon chips) comes into contact with, ensuring production and manufacturing occur in an optimal environment space, which we refer to as a cleanroom. In accordance with international standards, the cleanliness level of a cleanroom is primarily determined by the number of particles per cubic meter that exceed the specified size criteria. In other words, "cleanroom" does not mean completely dust-free; rather, it maintains a very low level of dust. Of course, the particles that meet the dust criteria in this standard are already extremely small compared to common dust. However, for optical structures, even the slightest bit of dust can have a significant negative impact, making dust-free conditions an absolute requirement for the production of optical structure products.
As shown in the table, controlling the number of particles with a diameter greater than 0.5 micrometers to less than 3,500 per cubic meter meets the international Class A cleanroom standard. The cleanroom standard for chip-level production and processing demands higher dust control than Class A, with such high standards primarily applied to higher-grade chip manufacturing. The particle count is strictly limited to less than 1,000 per cubic meter, which is commonly referred to in the industry as the 1K level.
