Why use yellow light in clean rooms

The use of yellow light (wavelength of about 590-620 nanometers) in modular clean rooms is to reduce the potential impact on photosensitive materials and equipment, while ensuring operational efficiency and safety in a clean environment. Yellow light can not only effectively reduce ultraviolet (UV) radiation from the light source, but also enhance the lighting effect of visible light, thereby reducing damage to sensitive products, especially in the fields of Semiconductors, optoElectronic devices, and biopharmaceuticals.

Reduce damage to photosensitive materials

In many industrial applications, photosensitive materials are widely used in manufacturing and testing processes. For example, in semiconductor manufacturing, the photolithography process uses photosensitive adhesive to form circuit patterns. Using yellow light illumination can effectively avoid the impact of ultraviolet light on photosensitive adhesives, reduce the photochemical reaction of photosensitive adhesives, and thus reduce the defect rate. Studies have shown that the use of yellow light can reduce the damage rate of photosensitive materials to less than 5%, which is crucial to improving the yield and reliability of products.

• Photosensitive materials are widely used in semiconductor and optoelectronic fields

• Yellow light can reduce the damage rate of photosensitive adhesive to less than 5%

• Improve product yield and reliability

Improve operator comfort

Using yellow light not only helps protect sensitive materials, but also improves operator comfort. Compared with white light, yellow light is less irritating to the eyes and can effectively reduce eye fatigue and discomfort. According to research data, the work efficiency of operators can be increased by about 20% in an environment with yellow light. This comfortable working environment can encourage operators to focus more on details, thereby reducing the risk of operating errors.

• Yellow light reduces eye irritation

• Improve operator efficiency by about 20%

• Reduce the risk of operating errors

Matching clean room standards requirements

In the design and operation of clean rooms, following international standards is an important measure to ensure a clean environment. According to ISO 14644, the light intensity in a modular clean room should meet certain standards to ensure that there will be no accidents due to insufficient light during cleaning and operation. The use of yellow light can meet these standards, and at the same time, it is energy-efficient and can effectively reduce energy consumption. Clean rooms using yellow light can reduce energy consumption by 15%-30%, achieving both environmental and economic benefits.

List of relevant standards and specifications

• iso 14644-1: Air cleanliness standard

• iso 14644-2: Clean room monitoring standard

• ISO 14644-3: Clean room performance test standard

• ISO 14644-4: Design and construction standard

In short, the use of yellow light in clean rooms not only meets clean room standards, reduces the risk of damage to photosensitive materials, but also improves the comfort and efficiency of operators. These factors together promote the manufacture and testing of high-quality products and ensure the overall performance of the Clean room environment.
