Important considerations for AOI inspection machines include the following:
Accuracy and resolution: The core function of the AOI inspection machine is to detect whether the pads, components and other connections on the circuit board are intact and whether there are short circuits, leakage and other problems. Therefore, it requires very high accuracy and resolution. When purchasing, you need to pay attention to the actual detection accuracy of the detection machine and whether its small resolution can meet the requirements.
Inspection speed and efficiency: Since the production line needs to pursue high efficiency, the AOI inspection machine needs to have the ability to detect quickly. During the detection process, it is also necessary to ensure that the false positive rate is low to avoid increasing subsequent costs and workload.
System accuracy and running speed: This is mainly reflected in the false rate and error rate of input and output data during programming, detection, and statistics of AOI automatic optical inspection, as well as repeatability, etc. In addition, the running speed of AOI automatic optical inspection during automatic operation is also a key point, and time costs need to be minimized while ensuring accuracy.
Stability and ease of use: When measuring high-precision and miniaturized components, the AOI automatic optical detector with good stability is not susceptible to conversion variations of multiple organizations and multiple overlaps, multiple layers of fine spacing, and multiple lines and multiple data. Influence. Ease of use is reflected in the convenience of setting up. The application of the detector is simple and direct, it can be switched freely and it is easy to get started.
Manufacturer and after-sales service: AOI automatic optical detectors from different manufacturers are different in terms of facility environment, product process quality, market positioning, etc. Therefore, before choosing a detector, you should understand the background of the manufacturer to reduce risks. In addition, good after-sales service is also an important factor to consider, including the supplier's brand, number of engineers and professional capabilities, distribution points of physical service stations, maintenance conditions and periodicity, etc.
In general, many factors need to be considered when choosing an AOI detection machine, including accuracy and resolution, detection speed and efficiency, system accuracy and stability of operating speed, ease of use, manufacturer and after-sales service, etc.
