Sipotek is a professional china automated optical inspection machine manufacturers located in shenzhen city,major products including visual inspection machine and automated optical inspection (AOI) machine.
Automation is defined as the process by which machines, equipment, systems or processes are steadily detected, judged, processed, analyzed, and controlled to accomplish a desired objective without direct involvement one or more persons , according to the needs of the man.
Automatic Optical Inspection (AOI) is an automated visual inspection of the manufacture of printed circuit boards (or transistors, LCDs) in which a camera independently scans the device being tested for catastrophic failures (for example, missing components) and quality defects (i.e. shape, inclined component, etc.). It is used commonly in the production process as it is a contactless test method. At several stages, it is implemented throughout the production process, including bare-edge inspection, welding glue inspection (SPI), post-reflow and pre-reflow phases, and other stages as well

Historically, the main place of AOI systems was after soldering or remolding “post-production”. Especially because AOI systems – post-reflow, can inspect most types of defects (component placement, missing solder, solder shorts, etc.) at a single point in the chain with a single system. In this way, the defective cards are reprocessed and the other cards are sent to the next step of the process.
Automated or automatic optical inspection (AOI) is a vital technique used in the manufacturing and testing of electronic printed circuit boards. Automatic optical inspections, AOI enables accurate and fast assessment of electronic components, especially printed circuit boards, to make sure that the quality of the product coming out of the production line is high and that the items are properly built and without any manufacturing defects.
