Integrated Endoscope Camera Module

1.Design and R&D Phase
The process of Integrated Endoscope Camera Module starts with design and R&D, where the R&D team first conducts demand analysis based on target application scenarios to confirm core parameters such as module resolution, probe diameter, light source type, and material standards. Then, they complete schematic design (including circuit layout for image sensors and signal processing units), structural design, and optical design, and produce prototype modules through 3D printing and small-batch processing. The prototypes are further tested for imaging clarity, size adaptability, and basic performance, and the design scheme is optimized repeatedly until it meets the preset technical indicators.

2. Core Component Procurement and Incoming Inspection
After the design is finalized, the procurement team selects qualified suppliers to purchase core components, including high-precision CMOS/CCD image sensors (medical-grade ones need to meet ISO 13485 standards), optical glass lenses (or wide-angle lenses for panoramic scenarios), miniature LEDs, stainless steel/plastic structural parts, and PCB boards. All components undergo strict incoming inspection: for example, image sensors are tested for pixel integrity and signal stability, glass lenses are checked for transmittance and distortion, and medical-grade structural parts are verified for biocompatibility. Only components that pass the inspection are put into the production link to avoid affecting the final product quality.

3. Core Production in Dust-Free Workshop
The core production of the module is carried out in Class 10/100 COB dust-free workshops to prevent dust from interfering with precision components. First, the SMT (Surface Mount Technology) process is used to mount small components such as chips, resistors, and capacitors onto the PCB board with high precision, ensuring stable electrical connections. Next, the COB (Chip on Board) process is adopted to directly bind the image sensor chip to the substrate, which improves the module’s integration, reduces volume, and enhances heat dissipation performance—critical for ultra-miniature medical probes. Finally, the AA (Active Alignment) process is implemented: the lens group is automatically adjusted and aligned with the image sensor through professional equipment, ensuring that the light focus is accurately projected onto the sensor to avoid imaging blur, and the aligned components are fixed with high-temperature glue to ensure long-term stability.

4. Module Assembly and Integration
After the core components are produced, the assembly stage begins: workers (or automated equipment) integrate the COB/SMT-processed PCB board, the AA-aligned lens group, the built-in LED light source, and the structural shell into a complete module. For medical modules, special attention is paid to the fit between components to ensure that the shell can withstand subsequent sterilization; for industrial modules, waterproof gaskets are installed at the connection points to meet IP67/IP68 protection standards. During assembly, real-time sampling inspection is conducted to check whether the module’s appearance, size, and component installation meet the requirements.

5. Performance and Reliability Testing
The assembled modules enter the testing phase, which includes two major categories: performance testing and reliability testing. Performance testing covers imaging clarity (testing resolution up to 4K/8K), auto-focus speed, LED brightness uniformity, signal transmission latency, and interface compatibility. Reliability testing is scenario-specific: medical modules undergo repeated high-temperature autoclaving or ethylene oxide sterilization tests to verify sterilization resistance; industrial modules are tested for high-temperature resistance, low-temperature resistance, and drop resistance. In addition, medical modules also need to pass electrical safety tests to ensure patient safety.

6. Sterilization, Packaging, and Pre-Shipment Inspection
For medical-grade modules that pass the test, they are sent to a professional sterilization workshop for final sterilization, and then sealed in sterile packaging with sterilization indicators to prevent secondary pollution. Industrial modules are packaged with shockproof and dustproof materials to adapt to transportation environments. Before shipment, all modules undergo a final pre-shipment inspection: sampling is conducted to re-test key performance indicators, and the packaging integrity and label information are checked. Medical modules also need to be accompanied by compliance documents such as CE/FDA certificates. Finally, the qualified modules are sorted according to orders and delivered to customers through logistics channels that meet the requirements.​
