Aoi automatic optical inspection is the best machine that improves the efficiency and efficacy of the working regarding the inspection.

It improves quality. You will also examine the rapid improvement in process control and operational efficiencies. Establish repeatable and verifiable standards are the most important features of the machine.

We are much vigilant about the time-sensitivity of our customers. That is the reason; reduction in training time is another fruitful aspect of the machine.

Circuits are more complex. It is almost impossible to inspect the boards manually, and thus AOI has a pivotal and important role for checking printed circuit boards after assembly. I

t will surely assist you to attain the desired product quality in the production line.

You need not worry about the complexity of the functions because the whole process is fully automated. You will be able to perform all its functions automatically.

Their coast is kept low to facilitate you in more effective ways. The costs of work reduction will help you to save money and invest in another project to grow up in a highly competitive market.

If you are looking for a reliable inspection machine to make your working examination more effective, then the AOI automatic optical inspection is perfect for you. That is more reliable.

Most of its functions are automated. You need not engage large human resources to perform the function regarding an inspection. This aspect will surely save your money as well time.

You must make the machine part of your collection. Enjoy the automatic functions of the machine and increase your production.

In the early PCB production, the inspection was mainly completed by manual inspection combined with the electrical inspection. With the development of electronic technology, the PCB wiring density continues to increase,

There have more and more difficulty of manual inspection, the false positive rate increases, and manual inspection is bad for Health, electrical test programming is more cumbersome, the cost is also higher, and still, a lot of defects cannot be detected. Therefore, AOI automatic optical inspect machines are increasingly used in PCB manufacturing

Aoi Automated Optical Inspection application in SMT factory:

• PCB inspection , PCB defects can be roughly including short circuits (including base copper short circuit, thin wire short circuit, electroplating open circuit, dust short circuit, pit short circuit, repetitive short circuit, stain short circuit, dry film short circuit, insufficient etch short circuit, plating short circuit, scratch Short circuit, pleated short circuit, etc.), open circuit (including repetitive open circuit, scrape open circuit, vacuum open circuit, gapped open circuit, etc.) and other defects that may lead to PCB scrap (including over-etching, electroplating scorch, pinhole), produced in PCB In the process, the production of the substrate and copper plating may produce some defects, but the main defects are generated after the etching. AOI is generally detected after the etching process, mainly used to find the missing parts and excess parts on it
• Solder Paste printing inspection,Solder paste printing is the initial link of SMT and the source of most defects. About 60% -70% of defects appear in the printing stage. If the defects are eliminated at the initial link of the production line, the loss can be minimized and the cost can be minimized. , Many SMT production lines are equipped with AOI testing for printing.There are many types of printing defects, which can be roughly divided into insufficient solder paste on the pad and too much solder paste; scratching of the solder paste in the middle of the large pad, sharpening of the solder paste at the edge of the small pad; printing offset, bridging and Contamination, etc.  The causes of these defects include poor solder paste rheology, improper template thickness and hole wall processing, unreasonable printer parameter settings, low precision, improper choice of scraper material and precision, poor PCB processing, etc., through AOI Can effectively monitor the quality of solder paste printing, and analyze the number and type of defects to improve the printing process
• Surface Mount inspection,The component placement process has high requirements for equipment accuracy. Common defects include missed placement, wrong placement, offset skew, and opposite polarity. AOI inspection can monitor the above defects, and can also inspect the solder paste on the pad connecting the close pitch and BGA components here
• Reflow inspection, In the back-end inspection of reflow soldering, the inspection system can check for missing, offset, and skewed components, as well as all defects in polarity, and must also be correct for solder joints and insufficient solder paste, short-circuit soldering, and tilted feet. Defect detection, reflow soldering back-end inspection is currently the most popular choice for AOI, this location can find all assembly errors, providing a high degree of security
