1. Equipment performance parameters
Heating temperature range:
Select the appropriate heating temperature range based on the characteristics of the coating material and process requirements. For example, some materials may require high temperatures to form high-quality films, while others are more temperature sensitive and require coating at lower temperatures.
Temperature control accuracy:
High precision temperature control is crucial for ensuring the uniformity and quality of thin films. Therefore, a PECVD coating electric furnace with high-precision temperature control function should be selected.
Vacuum degree:
Vacuum degree is one of the important factors affecting the quality of coating. PECVD coating electric furnace that can achieve the required vacuum degree should be selected to ensure stable gas atmosphere during the coating process and reduce impurity pollution.
RF power supply power and frequency:
The selection of RF power and frequency should be determined based on the characteristics of the coating material and process requirements. High frequency power supplies typically provide better ion bombardment and film uniformity.
Gas flow control system:
Accurate gas flow control is crucial for ensuring coating quality. PECVD coating furnaces equipped with high-quality flow meters and stable gas supply systems should be selected.

2. Equipment structure and materials
Reaction chamber structure:
The structural design of the reaction chamber should be reasonable, easy to clean and maintain. Meanwhile, the size of the reaction chamber should be determined based on the size and quantity of the samples to improve production efficiency.
Furnace material:
The furnace should be made of materials that are resistant to high temperatures and corrosion to improve the service life and stability of the equipment.
Heating element:
Heating elements should be made of materials with long lifespan and high efficiency, such as graphite, tungsten wire, etc. Meanwhile, the layout of heating elements should be reasonable to ensure uniform temperature inside the furnace.

3. Equipment reliability and safety
Equipment stability:
Choose a PECVD coating electric furnace with good stability and low failure rate to reduce downtime and maintenance costs during the production process.
Security protection measures:
The equipment should have comprehensive safety protection measures, such as over temperature protection, leakage protection, etc., to ensure the safety of operators.

4. After sales service and technical support
after-sale service:
Choose a manufacturer that provides comprehensive after-sales service so that any problems encountered during use can be promptly resolved.
technical support:v Manufacturers should have a professional technical support team that can provide technical support for users in equipment debugging, process optimization, and other aspects.

5. Cost effectiveness and customization options
cost performance:
On the premise of meeting the process requirements, choose a cost-effective PECVD coating electric furnace to reduce production costs.
Customization options:
If there are special requirements, such as reaction chambers of special sizes, specific gas flow control systems, etc., manufacturers that provide customized services can be chosen.

6. User reviews and market feedback
User reviews:
Refer to the usage evaluations of other users to understand the performance, stability, and after-sales service of the device.
Market feedback:
Pay attention to market feedback and understand the performance and user satisfaction of different brands and models of PECVD coating electric furnaces in the market.
