PCB Technical - Advantages of pcb

Machine vision inspection technology has other inspection plans and technical advantages that cannot be compared with traditional inspection methods, and is widely used in various major industries. Among them, the application of machine vision inspection equipment in PCB board is more used. The following introduces the advantages of machine vision inspection equipment in detecting PCB defects.

1. The PCB inspection system software regularly checks and corrects PCB shortcomings. The cost during the entire inspection period is far less than the cost after the final inspection and inspection.

2. It can detect incorrect repeatability as soon as possible, such as patch offset or incorrect tray installation.

3. Show SPC materials to the processing technology staff. The data analysis function of PCB inspection technology and the integration of SPC processing technology management methods and technologies have shown a strong weapon and equipment for the appropriate soundness of the SMT production process, and the output rate of the PCB assembly line has been significantly improved. With the expansion of modern processing and manufacturing operations, manufacturing control plans have become more and more critical, and the requirements for SPC materials have continued to increase. The use of PCB inspection technology will increasingly highlight its necessity.

4. It can be incorporated into the regulations of further increasing the relative density of PCB assembly. With the substantial increase in the relative density of electronic equipment assembly, some traditional inspection technologies, such as ICT, can no longer be integrated into the development trend of SMT technology. The emergence of 0402 built-in components has long made ICT impossible to detect, while PCB inspection Technology is not susceptible to such elements.

5. The conversion of test code is very fast. The test code of PCB machine vision inspection equipment can be converted into CAD material immediately, which is very convenient. Compared with ICT, because there is no need to make professional fixtures, the inspection cost is also greatly reduced.

6. It can keep up with the manufacturing rhythm of SMT production line. At this stage, many processing plants rely on manual visual inspection for PCB components during processing, but with the increase in PCB specifications and the number of components, this type of detection method has long been unbearable. However, PCB inspection technology can guarantee a rate of 0.1 second/frame at this stage, and the provision of free online inspection can be considered.

7. The reliability of detection is high. The factors of inspection are accuracy and reliability. Manual visual inspection has its limitations from beginning to end. PCB inspection technology prevents these disadvantages and maintains good accuracy and reliability.

8. Ensure product quality, reduce human capital costs, and improve labor efficiency.

9. Non-contact measurement, it is not easy to damage and scratch the PCB board.

10. In addition, machine vision inspection technology can perform daily tasks that could not be performed in the past: when solving some small tube angles, traditional methods are usually not available. The PCB inspection system software can detect 0201 (0.3mmPicth) components and intervals.
