ISO 7 Modular Cleanroom Solution for Plastic Technology in Spain
2026-08-10
Precision camera module assembly requires a controlled production environment to protect optical components, CMOS sensors, adhesives, and electronic components from contamination and environmental fluctuations.
For a smart door lock manufacturer in Zhuhai, China, AIRKEY delivered a 41㎡ ISO 7 modular cleanroom using the Castle Series. The cleanroom was designed specifically for 3D facial recognition camera module assembly and related precision manufacturing processes.

The customer's 3D facial recognition camera module production involved optical assembly, sensor lamination, focusing, CMOS board-level assembly, dispensing and curing.
These processes are highly sensitive to environmental conditions. Micro-dust on lenses or CMOS sensors can create imaging defects, while airflow and particles during focusing may affect optical precision. Electronic components such as photosensitive chips are also vulnerable to electrostatic discharge.
Temperature and humidity fluctuations can further affect adhesive curing, potentially resulting in debonding, light leakage, sealing problems and lens fogging. Metal debris from conventional production environments can also introduce cross-contamination during semi-finished product storage and module pre-assembly.
AIRKEY designed the Castle Series modular cleanroom around the specific requirements of precision camera module manufacturing.
The system combines controlled cleanliness, environmental stability, space-efficient access and factory-based quality verification to create a controlled production environment for optical and electronic assembly.
The cleanroom uses a combination of tempered glass and color steel panels. AIRKEY's patented frame and keel profiles provide structural strength while allowing future expansion and upgrades.
The transparent sections also improve production visibility without compromising the cleanroom enclosure.
Manual sliding doors were selected to avoid occupying additional aisle space or interfering with workstation layouts.
This configuration facilitates the movement of materials while maximizing the usable production area inside the 41㎡ cleanroom.
A dedicated constant temperature and humidity air-conditioning system with RFU was installed for the cleanroom.
The system supports internal air recirculation and helps maintain stable process environmental parameters while balancing airflow throughout the production area. This is particularly important for precision manufacturing processes affected by temperature, humidity and airflow variations.
Before shipment, the modular cleanroom was pre-assembled at AIRKEY's factory, where key parameters were checked for compliance.
After installation at the customer's site, cleanliness testing was conducted before final handover. The completed project passed on-site testing and met ISO 14644 cleanroom standards.
For precision industries such as optical components, camera modules and electronic assembly, a cleanroom is more than an enclosed production space. The system needs to maintain stable environmental conditions while supporting the actual production workflow.
AIRKEY's modular cleanroom approach combines:

The 41㎡ Castle Series modular cleanroom was successfully installed for camera module assembly in Zhuhai.
Following factory processing, delivery and on-site installation, the cleanroom underwent cleanliness testing. The project achieved the required parameters, complied with ISO 14644 cleanroom standards and was successfully accepted and handed over.
The project demonstrates how a modular cleanroom manufacturer can integrate cleanliness control, environmental stability and production-space optimization for precision camera module manufacturing.
The project described here uses an ISO 7 / Class 10,000 cleanroom for smart door lock camera module assembly. The appropriate cleanliness level should ultimately be determined according to the customer's process and product requirements.
Temperature and humidity fluctuations can affect dispensing and curing processes, potentially causing adhesive and sealing problems. The project therefore uses a dedicated constant temperature and humidity air-conditioning system with RFU.
Yes. The project uses AIRKEY patented frame and keel profiles designed to support future expansion and upgrades.
The cleanroom is pre-assembled and inspected at the AIRKEY factory before shipment. After site installation, cleanliness testing is performed before project handover.
