Overview
Electronic factory cleanroom engineering is a high-precision project that provides a dust-free, sterile, and suitable environment for specific industries by controlling parameters such as air cleanliness, temperature, humidity, and pressure. The following are the core points of cleanroom engineering: $r $n $r $n - -- $r $n $r $n1. Cleanroom classification $r $n - According to cleanliness level (ISO standard): $r $n - ISO levels 1-3: Ultra high standard (such as chip manufacturing). $r $n - ISO 4-5 level: Semiconductor, precision electronics. $r $n - ISO 6-8 level: Pharmaceutical aseptic production, medical devices. $r $n - ISO Level 9: General industrial or auxiliary areas
Product Details
Electronic Factory Cleanroom | Cleanroom Construction ProjectSystematic decision-making framework and implementation points for selecting clean room construction plans, combined with precision electronics industry standards and typical case analysis:
1Electronic Factory Cleanroom | Cleanroom Construction ProjectClarify the core process parameters
Cleanliness level matching
Determine according to production process requirementsISOLevel: If semiconductor lithography requires a thousand level（ISO 5），SMTSMT is suitable for tens of thousands of levels（ISO 6）Ordinary electronic assembly can be relaxed to the 100000 level（ISO 7）.
Control the concentration of particulate matter through air exchange rate, for example, the air exchange rate in a cleanroom of Class 1000 is ≥300time/Hours, high-efficiency filters need to cover ≥80%Ceiling area.
Environmental control indicators
Temperature and humidity setting: semiconductor workshop temperature22±2℃, humidity45±5%，PCBThe workshop can be relaxed to24±1℃, humidity50±10%.
Pressure gradient: The pressure difference between the clean area and the non clean area is ≥5PaBetween different levels of zones ≥3Pa.
2、 Selection of Key System Design
Air purification system
Adopting three-stage filtration (initial effect)G4+Medium efficiencyF8+efficientH13）Combination, the semiconductor workshop needs to add chemical filters to process acidic gases.
The airflow organization prioritizes downward vertical laminar flow and upward vertical laminar flow,FFUCoverage rate ≥60%At the same time, the stability of cleanliness is improved30%.
Anti static and corrosion-resistant treatment
The ground adopts anti-static epoxy self leveling (resistance value)1×10^6~1×10^9Ω) orPVCRoll material, use anti-static color steel plate on the wall (surface resistance ≤1×10^9Ω).
The acid-base waste gas discharge pipeline adopts316LStainless steel, welding helium leak detection rate ≤1×10^-9 Pa·m³/s.

Modular construction process
divide32Synchronous construction of individual units, installation error of color steel plate ≤±3mmThe joint seam of the ceiling panel is ≤2mm.
After the pre embedded pipelines are completed, purification and decoration can be carried out to reduce the risk of cross contamination.
Clean control measures
Set up a pre cleaning area, wipe the color steel plate with isopropanol before entering the site, and the construction personnel should wear integrated dust-proof clothing.
Dynamically monitor the number of suspended particles, and ensure that the particle concentration during construction does not exceed the design value30%.
