1. Equipment performance
Sedimentation rate:
The sedimentation rate is one of the important indicators for evaluating the performance of PECVD equipment. A faster sedimentation rate can improve production efficiency and reduce production costs.

Film thickness and uniformity:
The thickness of the film should meet the application requirements, and the uniformity of the film thickness should be good. The intra film uniformity and inter film uniformity should generally be controlled within ± 4% to ensure consistency in coating quality.

Adhesion strength:
The adhesion strength of the coating is crucial for the reliability and service life of the product. Equipment with high adhesion strength and good bonding strength should be selected.

2. Equipment configuration and process compatibility
Reaction chamber design:
Tube type PECVD systems typically use quartz tubes as deposition chambers to ensure uniform distribution of process gases and stable generation of plasma.

Heating method:
The heating method affects the control accuracy and stability of the coating temperature. Resistance furnace is a commonly used heating method, and the temperature control range should be adjustable between 100~1700 ℃ to meet the needs of different processes.

Gas system:
The gas path system should be designed reasonably, including the inlet, outlet, and gas flow control system, to ensure accurate proportioning and stable supply of process gases.

RF source:
The RF source is a key component for generating plasma, and its output power and frequency should be adjustable to meet the requirements of different processes.

Process compatibility:
Choose equipment that is compatible with multiple process gases to meet different material and coating requirements.

3. Equipment stability and reliability
Equipment stability:
The equipment should have high stability, be able to operate stably for a long time, reduce failure rates and downtime.

Maintenance convenience:
The structure and design of the equipment should be easy to maintain and upkeep, reducing repair costs.

4. Equipment safety and environmental friendliness
Security:
The equipment should comply with safety standards, such as explosion-proof, anti electric shock, fireproof, etc., to ensure the safety of operators.

Environmental friendliness:
The equipment should meet environmental protection requirements, reduce emissions of exhaust gas, waste liquid, noise, and other aspects, and minimize its impact on the environment.

5. Manufacturer's Strength and Service
Manufacturer strength:
Choose manufacturers with rich experience and good reputation to ensure the quality and performance of the equipment.

after-sale service:
Good after-sales service can ensure that any issues with the equipment during use are promptly resolved, ensuring smooth production.

6. Specific selection suggestions
Determine application requirements:
Specify the specific requirements for the type of coating material, film thickness, uniformity, adhesion strength, etc.

Comparing products from different manufacturers:
According to application requirements, compare the performance, configuration, price, and other aspects of equipment from different manufacturers, and choose the equipment with high cost-effectiveness.

Field investigation and sample testing:
If possible, you can conduct on-site inspections of the manufacturer's production base to understand the production process and quality control procedures of the equipment. At the same time, the manufacturer can be requested to provide samples for actual coating testing to verify the performance of the equipment.

Contract signing and acceptance:
After determining the purchase intention, sign a detailed contract with the manufacturer, specifying the technical specifications, delivery time, after-sales service, and other contents of the equipment. After the equipment arrives, it will be inspected according to the standards stipulated in the contract to ensure that the equipment meets the requirements.
