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.
Today we will talking about assembly industrial automation and automatic optical inspection systems or equipments.
Automation may be described as a situation whereby systems, machines, processes, or equipment are regularly evaluated, detected, analyzed, processed, and controlled to achieve the desired goal without directly involving one or more people, depending on the needs of the situation.
Automatic Optical Inspection (AOI) is an automatic visual inspection of printed circuit board (or LCD, transistor) production for which a camera scans the device under test independently for disastrous failures (e.g. missing components) and quality defects (e.g. inclined component, shape, etc.). Because it is a contactless test method, it is commonly used in production processes.
It is implemented throughout the production process in several steps, including post-reflow, sharp edge inspection, SPI (glue welding), and pre-reflow phases, as well as other steps.
According to history, the main place of AOI machine was after reassembly or welding “post-production”. Particularly, because AOI – post-reflow systems – can examine many types of defects (missing solder, component placement, welding short circuits, etc.) at one point in the chain with one system. By this way, the defective cards are processed again and the rest cards are moved to the next step of the process.
Automatic or Automated optical inspection (AOI) is an essential technique used in the production and testing of electronic printed circuit boards. Automatic optical inspections, AOI allows for a fast and accurate evaluation of electronic components, in particular printed circuit boards, to ensure that the quality of the product leaving the production line is good enough and that they are constructed correctly and with no manufacturing defects.
Why is there need for an automatic optical inspection, AOI?
Despite significant improvements, modern circuits are far more complicated than circuits produced a few years ago. The innovative surface mounting technology and subsequent reduction in size makes the panels very compact. Relatively average printed circuit boards have tons of soldered joints, and this is where many of the problems are found.
This increase in the complex nature of printed circuits also means that manual inspection is not a powerful option these days. Even at the time this approach was accepted, it was understood that it was not effective, the inspectors got tired easily and the wrong construction was difficult to detect. Now that the market requires large and high quality products to come to market very fast, very timely and reliable methods are required to ensure that the quality of the product remains high.
AOI, automatic optical inspection, is an important tool in an integrated electronic test strategy that ensures that costs are minimized by detecting faults at the beginning of the production chain.
A way out of this quagmire is to use automated or automatic optical control systems. Automated optical inspection machines can be applied to the production line just after the welding process. In this way, they can be used to identify problems in the early stages of the production process. There are many advantages to this. With more expensive failures to be further adapted in the production process, they are obviously the ideal place to look for faults.
In addition, problems in the welding and assembly area can be discovered at the early stages of the production process and the information is used to quickly send feedback to the previous phases. In this way, a rapid response can help ensure that faults are quickly recognized and resolved before too many PC cards are designed with identical problems.
