Choose a good AOI equipment to consider the following key factors:

1. Detection capability: Different AOI equipment may have different detection capabilities, including resolution, detection speed, detection accuracy and so on. According to their own needs, choose the right equipment that can meet the requirements for the detection of welding quality, surface defects and other aspects.

2. Flexibility: Consider the flexibility and adaptability of the equipment. Good AOI equipment should have adjustable parameters, scalable functions and the ability to adapt to a variety of electronic products or components. Able to flexibly respond to changes in different products and manufacturing processes.

3. Reliability and stability: choose the reliability and stability of the AOI equipment, able to operate stably for a long time, reduce the frequency of failure and maintenance, improve productivity.

4. software features: focus on the software features of the equipment, including image processing algorithms, defect detection algorithms and results analysis functions. Consider the ease of use of the software tools and interfaces provided by the equipment, and whether it can be integrated with other production processes or systems.

5. Routine maintenance and support: Choose a supplier with a good maintenance and support system. Understand the supplier's after-sales service, technical support and training support, etc., to ensure that timely help and support can be obtained in the process of use.

6. Cost-effectiveness: Consider the price, performance and reliability of the equipment, as well as the subsequent maintenance costs and operating costs. Select the AOI equipment that can provide a good price/performance ratio.

7. Reference to evaluations and cases: Check relevant market evaluations and customer cases to understand the reputation and actual application of different suppliers and equipment, which helps to make a more accurate choice.

The most important thing is to conduct sufficient research and comparison according to the actual needs, and choose the AOI equipment that suits your production process and needs.
