German Project - Anti-static Cleanroom for the Electronics Industry
Client: A German precision electronic component manufacturer (mainly producing automotive sensors and micro-circuit boards)
Client Source: Online inquiry channel on the company website
Work Requirements: Custom-designed anti-static cleanroom for the electronics industry. The core requirement is to meet the high anti-static standards for automotive electronic component production, be compatible with PCB board mounting and sensor chip packaging processes, and comply with German industrial cleanroom standards to ensure stable operation and data traceability.
Work Process:
1. Online Inquiry, Precisely Matching Anti-static Needs:
The German client submitted an inquiry through the company website, clearly stating that their automotive sensors are extremely sensitive to static electricity. Static interference in normal environments can easily lead to chip breakdown and short circuits. Therefore, they have stringent requirements for the cleanroom's anti-static indicators: the anti-static resistivity of the floor and walls must be stable between [value missing] and [value missing], the overall grounding resistance must be <4Ω, and the cleanroom must meet ISO 7 cleanliness standards to meet particulate contamination control requirements. Chris and its technical team responded collaboratively, confirming detailed parameters such as the client's workshop dimensions, production line layout, and equipment placement via email and video conference. They provided a preliminary solution framework addressing core needs including anti-static design, cleanliness control, and data monitoring systems.
2. Customized Design, End-to-End Anti-static Solution
To meet the client's stringent anti-static requirements, the technical team tailored a cleanroom solution specifically for the electronics industry. Key design highlights include:
●Full-Area Anti-static Structure Construction: The floor uses anti-static epoxy resin self-leveling compound, coupled with a conductive copper foil grounding network to ensure rapid static discharge; conductive color steel plates are used for walls and ceilings, with conductive adhesive sealing between the plates to eliminate dead zones for static accumulation; anti-static tempered glass is installed in doors and windows, and conductive sealing strips are added to door frames, achieving a closed-loop anti-static system for the entire cleanroom.
●Dual Protection Against Static Electricity and High Cleanliness: Equipped with a three-stage filtration system (pre-filter + medium-efficiency filter + HEPA filter) and an FFU (Fan Filter Unit) to maintain ISO 7 cleanliness (≥0.5μm particle concentration ≤352,000 particles/m³); a pulse-type ion fan is also installed to neutralize static ions in the air in real time, controlling the surface static voltage within the cleanroom to ≤100V, eliminating dual contamination from static electricity and particulate matter at the source.
●Intelligent Monitoring System Configuration: Includes an online anti-static monitor, particle counter, and temperature, humidity, and differential pressure sensors. Data is uploaded to the customer's production management system in real time, supporting remote viewing and historical data traceability, meeting German industrial digital management requirements; an anti-static grounding alarm device is also included, providing immediate warnings if grounding resistance exceeds the standard, ensuring production safety.
●Modular Assembly for Adaptability to Existing Production Lines: Utilizing an aluminum alloy modular frame, prefabricated components are pre-tested in the factory and quickly assembled on-site, eliminating the need for large-scale modifications to the customer's existing workshop and minimizing impact on production.
3. Rigorous Testing, Guaranteed Delivery Upon Compliance
●Finished cleanroom products undergo comprehensive testing at the factory, focusing on key indicators such as antistatic resistivity, grounding resistance, and cleanliness particle concentration. All data meet or exceed customer requirements, and a test report conforming to German industrial standards is issued.
●Finished products are packaged in standardized, moisture-proof and impact-resistant materials and shipped to Germany via international logistics. The entire logistics and customs clearance process is monitored to ensure timely delivery to the customer's factory.
Customer Feedback
The customer highly appreciates the cleanroom's antistatic performance and operational stability. After implementation, the yield rate of its sensor chips increased by 12%, and the product scrap rate due to static electricity decreased to below 0.1%. The modular design's convenience and the practicality of the intelligent monitoring system perfectly complement its digital production model, and the customer has expressed a clear intention to expand production.
