The Application of AOI in Reflow Inspection

Monday, December 24th, 2018

Today, we continue to talk about AOI technology applied in the PCB manufacturing. The component mounting inspection is followed by the reflow inspection, if you would like to know more details, please click The Application of AOI in Component Mounting Inspection to know.

AOI can be divided into two types: preventing problem phase and finding problem phase. The inspections after solder paste printing and SMT belongs to preventing problem phase and the inspections followed by reflow soldering are finding problem phase.

In the back end inspection of reflow soldering, AOI technology is able to detect some problems as below:

√ whether the components are missed, deviated or skewed.

√ The defects of polarity.

√ Whether solder joints are correct.

√ Whether the solder paste is enough.

√ Whether there is short circuit in soldering etc..

The back end inspection of reflow soldering is the most prevailing choice for AOI now. Because all of the assembly errors can be found at this process, so that the quality of printed circuit boards are able to step forward to a higher level.

Outlook of Headphone, Outlook of Wearable Devices

Wednesday, December 19th, 2018

People always find ways to decorate the electronic products those have been accompanied with them for a long time. Change a phone cover according to the dressing style or change a watch strap with different colors for Apple Watch. It seems that the technology devices have already become our accessories.

It has been a long time that technology combined with fashion. After all, a word “techno-fashion” became prevailing at the very beginning of 20th century. Therefore, we are able to see that Nike & Adidas do the same thing as a technology company — developing their new shoes. Meanwhile, Apple and Hermes launched Apple Watch to enter the luxury market.

It might be not very significant to say using technology to set off fashion or using fashion to set off technology, especially the wearable devices have begun to blend with daily dressing. And we have to admit that the headphone is the darling in the fashion crowds.

A number of NBA starts wore Beats to enter the field at the opening ceremony of 2008 Olympic Games. Since then, Beats headphone has become a fashion item favored by many stars and it can be seem in the street shoots or portraits of stars such as Lady Gaga, Justin Bieber, GD etc..

It is well known that headphone is a little gadget with small volume. Therefore, one of  the biggest challenges to make headphone integrates with wearable devices is that whether the components are small enough. For example, whether the printed circuit board are small enough to fit into the headphones.

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.

Solder paste printing, the very beginning of SMT, is the root of most defects on the PCB. The defects occur in printing process is up to 60%-70%. Thus, if the defects can be avoided in this link, then the damage is able to save cost minimized. Therefore, most of printed circuit board manufacturers have already equipped with AOI testing in SMT production lines.

There are various of printing defects, but they can be generally divided into insufficient or excessive solder paste, the solder paste in the middle part of large pads scraped etc.. The reason why these defects are formed including unreasonable setting of printing machine parameter, low accuracy, improper selection for scraper and so on. However, it is effective to monitor the solder paste printing by AOI technology and analyze the number as well as types of defects, so that enhance the capability of printing.

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

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.

Waymo to Launch Its Self-Driving Car Service in the Near Future

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.

Best Technology has been established for more than 12 years. In this period, we still spare no effort to be customers best partner of PCB and PCBA in China. If you would like to learn further information of us, please check our website: https://www.bestpcbs.com/
