The latest SMT Inspection Machines Available In India


SMT inspection systems now come with a range of technological innovations.
This article introduces readers to the latest models in the market.

Electronic products rely on surface mounted components. According to various experts in the SMT segment, 65 per cent of SMT defects and 50 per cent of electronics assembly errors are due to below par solder joint formation and solder paste printing. The solder paste deposition process is prone to defects and errors during the manufacturing process. These defects can be found either in the solder paste itself, or in the solder printing process. Hence, a complete paste inspection is instantly done after screen printing. This is required to ensure high yields, minimise rework/retesting and reduce overall scrapping costs. In the past few years, SPI and AOI systems have become crucial in PCB assembly lines, especially in those industries where safety and quality standards matter. Vendors now supply products that range from simple camera systems to complex three-dimensional (3D) X-ray systems, which can fit into almost any automated manufacturing line.

Let’s now take a quick look at the latest SMT inspection machines available in the market.
