Introduction

Semiconductor manufacturing plants, as high-value and high-tech facilities, are particularly vulnerable to flood risks. According to FM's FM1-40 flood protection standards and FM7-7 semiconductor facility standards, adopting FM Approved Flood Doors is a critical measure to protect semiconductor plants from flood damage. This article uses Shanghai Weiwang Technology's innovative application case in a semiconductor cleanroom as an example to showcase the exceptional performance of Weiwang Flood Doors in complex environments, while also introducing the flood protection requirements of FM7-7 standards and their significant importance in the semiconductor industry.

Project Background

Beijing Hanmin Microtest Technology Co., Ltd., insured by FM, is a global leader in electron beam inspection equipment under ASML. To ensure flood safety in the cleanroom area, Beijing Hanmin Microtest Technology Co., Ltd. selected Shanghai Weiwang Technology's independently developed Quick-Fit Buckled Flood Doors. This marks the first successful application of Weiwang Flood Doors in the semiconductor industry, signifying a major breakthrough for the company in high-standard environmental flood protection technology and setting a new benchmark for the industry.

Project Highlights and Technological Breakthroughs

1. Innovative Design to Address Complex Installation Conditions
   Addressing the issue of being unable to install flood doors on the exterior walls of the cleanroom, the team innovatively designed an interior-side installation solution using Z-shaped folding components, overcoming spatial constraints and ensuring the stability and reliability of the flood protection system.

2. Precision Construction Organization to Ensure Uninterrupted Production
   The construction team worked closely with the general contractor, utilizing nighttime and off-peak operations to minimize disruption to the cleanroom's daily production while efficiently advancing the project timeline.

3. Dust-Free Installation Compliant with Cleanroom Standards
   All welding operations were completed outdoors, and pre-assembled components underwent strict inspection before being brought on-site for installation, ensuring the integrity of the cleanroom environment and eliminating contamination risks during construction.

4. Precise Functional Testing to Ensure Reliability
   Due to the limitations of conducting traditional water closure and spray tests inside the cleanroom, the team employed specialized functional testing to ensure the flood doors met design standards and satisfied stringent flood protection requirements.

Technical Advantages of FM Approved Flood Doors

• Low Leakage Rate: Leakage does not exceed 0.08 gallons/hour/linear foot (1 L/hr/m).
• Rapid Installation: Quick-fit buckled design allows for fast installation, meeting urgent flood protection needs.
• High Reliability: Passed rigorous FM testing, demonstrating excellent durability and protective performance.
• Simple Maintenance: Requires only monthly inspections and annual maintenance to maintain long-term stable performance.

Summary

The successful implementation of this project once again highlights Shanghai Weiwang Technology's technical expertise and project execution capabilities in high-standard, complex environments. Through innovative design, precision construction, and rigorous functional testing, the Weiwang team successfully overcame multiple technical and environmental challenges, providing clients with efficient and reliable flood protection while setting a new benchmark for high-standard flood protection projects in the semiconductor industry.
