Electroplated plastics refer to the deposition of a
metal layer on the surface of a plastic substrate by electroplating technology,
which is usually used to improve the conductivity, wear resistance and
aesthetics of the material. This material has been widely used in many
Electronic and industrial applications. However, when using electroplated
plastics in A Clean Room environment, its particle release and chemical
stability need to be evaluated.
Environmental requirements for clean rooms
According to the ISO 14644 standard, the air cleanliness level of a modular clean room must meet the maximum allowable concentration of particulate matter in the air. For example, in an ISO5 clean room, no more than 3,520 particles (≥0.5 microns) are allowed per cubic meter of air. Therefore, all materials entering the clean room must meet strict cleanliness standards to avoid contamination.
iso 5 air particle limit: 3,520 particles/m3.
Temperature and humidity requirements: usually controlled at 20-24°C, 30%-60% Relative humidity.
Equipment and materials must meet clean standards to avoid particle release.
Risk of particle release from electroplated plastics
During use, electroplated plastics may release tiny particles due to surface wear or aging, which may affect the cleanliness of the clean room. According to research, the metal coating on the surface of plastic materials may peel off under stress or high temperature, thereby increasing the number of particles in the environment.
Surface wear leads to particle generation.
Improper use or environmental changes accelerate aging.
The risk of metal coating peeling increases at high temperatures.
Applicability of electroplated plastics in clean room applications
Under certain conditions, electroplated plastics can be used in modular clean rooms, such as in environments that are not prone to wear and have stable temperatures. However, rigorous evaluation and testing must be performed to ensure that it does not pollute the cleanroom environment. In addition, the selection of appropriate electroplating materials and processes is also crucial.
Based on the above analysis, the application of electroplated plastics in cleanrooms is challenging, but not completely unfeasible. Through strict material selection, environmental monitoring and maintenance, its impact on the cleanliness of the cleanroom can be reduced. For specific industries, such as electronics manufacturing, the reasonable use of electroplated plastics is still feasible, provided that relevant standards and specifications are followed.
