Multi-sensor measurement system has a wide range of application prospects in PCB inspection, which can help manufacturers to improve product quality and production efficiency, reduce production costs, and improve product reliability and stability.

Size Inspection: Multi-sensor measurement systems can acquire multiple parameters of a PCB, such as length, width, thickness, etc., from multiple sensors and measure them with high accuracy. This data can help manufacturers determine whether the PCB dimensions meet the design requirements and whether adjustments need to be made.

Surface defect detection: Multi-sensor measurement systems can acquire images of the PCB surface through image sensors and other devices, and use image processing techniques to detect the presence of defects on the surface, such as scratches, stains, and holes. These defects may cause the PCB to fail in subsequent use, so timely detection and treatment of these defects can improve product quality and reliability.

Solder joint inspection: Multi-sensor measurement systems can obtain information about solder joints on PCBs through infrared sensors, laser sensors, and other devices, and analyze them through algorithms to determine the quality of the solder joints. For example, the system can measure the shape, size, temperature and other parameters of the solder joints to determine whether the solder joints are well soldered and whether there are problems such as false soldering and cold soldering.

The application of multi-sensor measurement systems in PCB inspection requires selection and configuration based on specific inspection needs. Selecting the right optical measurement solution and data analysis technique is key to ensuring accuracy and reliability. At the same time, system integration and calibration are crucial steps to ensure the accuracy and repeatability of measurement results.
