Components are independent individuals in electronic circuits. The individual parts through which the current can produce frequency amplitude changes or change the flow direction are called devices, otherwise they are called components. In semiconductor circuits, transistors (transistors, diodes, thyristors, etc.) are devices, and resistors, capacitors, and inductors are components, which together are called components. Electronic components have different packaging types, and different types of components have the same appearance, but the internal structure and use are quite different. Therefore, it is difficult for inexperienced people to distinguish, but it is easy to distinguish SMD diodes and SMD capacitors from other SMD components. SMD components have a common feature, which is the logo.

With the development trend of technology, everyone’s regulations on the interactive experience of electronic devices are getting higher and higher. As a new generation of electronic devices, the touch screen is gradually becoming a tablet, mobile phone, free e-book, GPS, arcade game console and other devices. New love. The touch screen production process is complicated, from the upstream and downstream ITO glass coating, lithography, IC component production and processing, to the middle and upper reaches of the touch screen touch panel cater, ink printing, laser cutting, and then the middle and downstream touch screen touch panel caters to the rear cover. Laminated glass inspections clearly set higher requirements on the processing technology, so that the machine vision inspection equipment-inspection machine becomes the manufacturing equipment required for production and quality inspection at the relevant stage.

Appearance defect inspection equipment automatic appearance inspection, which is based on optical principles, and uses image analysis, computer and automatic control technology to detect and deal with defects encountered in production.

Circuit board component recognition and inspection-capacitor appearance size inspection equipment
