Types of Solder Paste Inspection Machines

Solder paste inspection machines are divided according to their inspection methods, ranging from visual inspections to automated AOI systems. They are also categorized based on how the PCB is presented for inspection, which can be in a conventional inline manner, as a compact system that offers a flexible inspection solution, or in a standalone design. Furthermore, the solder paste inspection machines are differentiated based on the scanning methods used. Some use a standard camera-based method to capture images and analyze them, while others are equipped with 3D imaging technology that offers a more in-depth analysis.

• By Inspection Method: The Solder Paste Inspection (SPI) machines primarily focus on the inspection of solder paste application. As the solder paste inspection machine suggests, its main duty is to correct the defects after solder paste application before the PCB assembly process. In some cases, it could even help reduce the defects that could arise after the solder inspection is performed. However, some consider the SPI inspection to be a part of visual inspection criteria set up by the AAO (Applied Artificial Optics) standards. According to the AAI (Applied Artificial Intelligence) standards, visual inspection would mean that a human operator would visually analyze and inspect the solder paste placements on the PCB boards. Unlike the human visual inspector system, solder paste inspection machines rely on advanced camera technology to analyze the PCB boards. The inspection method can be further categorized into 2D solder paste inspection machines and 3D Solder Paste Inspection Machines. While the 2D inspection machines rely on the contrast of images and solder paste to analyze and detect errors, the same goes for the 3D inspection machines but at a more advanced level of depth.
• By PCB Presentation Method: The way PCB is presented for inspection also plays a major role in how the solder paste inspection machine will be used. Inline Solder Paste Inspection Machines are integrated into the production line, usually between the solder paste application and the PCB assembly stages. It provides real-time detection of solder paste application errors, reducing the need for rework and enhancing overall production efficiency. Because of its placement, staff will have an easier time getting the PCB boards ready for assembly as they can inspect them before they reach the assembly line. Standalone Solder Paste Inspection Machines are separate units used to inspect solder paste application before PCB assembly. While Inline machines provide continuous inspection throughout the production process, standalone machines offer isolated inspection capabilities. The SDA (Solder Paste Defect Analyzer) would provide a solution for people looking to purchase a Solder Paste Inspection machine as it offers a standalone machine that is also portable.
• By Scanning Method: As mentioned before, Solder Paste Inspection machines are distinguished based on their scanning methods. 2D Measurement Machines provide a quick and easy way to inspect the amount, shape, and position of solder paste deposits, which means screen printing accuracy can be determined almost instantly. The machines offer fast inspection speeds and typically have a speed of less than 1 second per image. Depth measurement machines, on the other hand, utilize the same principle as 2D measuring SPI machines but at a more in-depth level. These inspection machines can not only provide information about the geometry of the solder paste but also provide information about the volume of the solder paste which means users will have a clearer understanding of the PCB board before it goes into the assembly process. Overall, efficiency is improved, and 3D solder paste irregularities can be analyzed.
