The Application of AOI in Component Mounting Inspection

Monday, December 17th, 2018

In the previous articles, we have talked about PCB inspection and solder paste printing inspection. To find more information of the details, please check: The Application of AOI in PCB Inspection and The Application of AOI in Solder Paste Printing Inspection.

The component mounting requires high precision of equipment and the common defects including forgetting to mount the component, mounting the component in a wrong way, polarity reversal etc.. AOI technology not only can find the defects above, but also can check the connection dense spacing and the solder paste on the pads of BGA component.

 

Since the component mounting is followed by the reflow soldering, the testing after component mounting is usually called front end inspection of reflow soldering. However, it is meaningless from the perspective of quality guarantee. Because the defects can not be found in the reflow oven. The solder tin is able to correct by itself after melting in the reflow oven, so the the mounting displacement and solder printing status can not be detected on the substrate after soldering. In fact, the front end inspection of reflow soldering is incredible significant for quality guarantee as that the component mounting of all parts can be inspected before reflow soldering.

The alarm will be sent out if the defects are found by AOI technology. After that, the visual inspection will be carried out by the operator. If miss some components at this stage, it can be corrected by tweezers. After the visual inspection operator repaired the same problem for many times, he will ask the person who charge the production equipment to reconfirm whether the setting of the machine is reasonable. The feedback information is very helpful to enhance the production quality and it can improve it in a very short time.

The Application of AOI in PCB Inspection

Monday, December 10th, 2018

AOI technology possesses the functions of PCB inspection, solder paste printing inspection, component inspection and assembly inspection after welding. In this article, we mainly talk about PCB inspection.

PCB Inspection

PCB inspection are mainly relied on the visual inspection combined with electrical inspection during the early PCB production. Best Technology, on the other hand, present many benefits of AOI testing to everyone. AOI testing is a popular choice due to the following features:

√ with the development of electronic technology, the wiring density of PCB is getting higher, which increases the difficulties in visual inspection.

√ Decrease the rate of mis-judgement.

√ Able to reduce harm to the health of inspector.

√ Save cost.

√ Avoid the electronic inspection technology can not inspect some defects.

PCBA AOI testing

AOI testing

In the process of printed circuit board manufacturing, there would be some defects on the substrate fabrication and copper clad. However, these defects are mainly produced after etching. By the way, AOI testing is usually used after etching and it is utilized to find out the missing or extra part on the rigid PCB.

Most defects can be found by AOI testing (excluding the missing inspection problem), but the main problem affecting its reliability is missing inspection. The dust produced in the processing of PCB could cause false warning, so the manual inspection must be carried out after using AOI testing to detect the defects.

Monday, December 3rd, 2018

If you are fascinated by the driveless car, Waymo which possesses the most autonomous technology in the world should be known absolutely. A news came a few weeks ago from John Krafcik himself, the CEO of Waymo. During the Wall Street Journal’s WSJ Tech D.Live conference, he announced that the Alphabet unit was planning on launching a driverless car service in the next two months, directly competing with Uber and Lyft.

On November 8, 2018, Waymo launched the driveless cars in Phoenix, Arizona, with no passengers in the front row but two engineers of data collecting in the back seat. Waymo established in 2016, and it soon acquired the relevant road test license, but in fact Waymo had began testing before its establishment. It looks like its driverless rides will hit the streets of Phoenix by the end of December. Or possibly early January.

Waymo does well in autonomous technology, but it still has shortcomings for cars. So they found Chrysler, a car brand of native American, which quickly agree with to work with former. Chrysler provided Waymo with 100 Pacificas cars and transformed them into driverless vehicles.

As we can see, an upwelling development of driveless car is coming. Best Technology believes that it will increase the demands of PCB, because the power control system, security control system and the electric system of vehicle cannot without printed circuit board.

Industrial Robots in PCB Industry?

Friday, November 30th, 2018

Nowadays,the application of industrial robots in PCB industry are in the stage of beginning and there are still lots of problems need to be solved. Many production lines in PCB industry are non-standard products (the products and equipments are do not based on the unified industry standards and specifications published by the country, but designed and fabricated by oneself according to one’s own needs).

However, there is still a long way to go to apply robots in the printed circuit board industry. Because the robots are limited by the existing working space and the ability of the original equipments in the process of application. Meanwhile, confronted with the application of various sensors to improve the intelligence of robots. All these factors influence the large-scale application of robots in PCB industry.

Although there are still some difficulties stuck the application of industrial robots in PCB industry, applied the robots into the PCB industry still have a bright prospect. The robots applied into the PCB industry will show a trend in the future as following:

  1. From single line application to multiple line application, the PCBmanufacturer need to invest a lot of money if they would like to introduce the robots to realize automated production. But they can expand the scale of application gradually after reforming the existing single line.
  2. From the application of simple robots to the application of AGV (Automated Guided Vehicle) combined with other intelligent devices, most of the material transfer between existing production lines is manual operation, which can be distributed by the combination of robots and AGV to achieve orderly material transfer.
  3. The application of robots in the original factory should be localized. But if the new plants need to realize automated production in full aspects, it means that introducing the application of robots and AGV is required.
  4. Get the process of manufacturing more intelligent and more flexible by the combination of industrial robots and IoT (Internet of Things).
