How to Choose a Professional PCB Assembly Company

Monday, November 18th, 2019

Hardware designers requiring turnkey PCB assembly services usually face tremendous obstacles for their need of prototyping and small batches. Large companies with huge inventory needs and long delivery horizons can wait for days or weeks for a proposal, while accepting large minimum quantity requirements. For them, delays associated with overseas manufacturing are no big deal. However, these conditions are simply unacceptable for small industries, engineers, makers, and entrepreneurs.

Best Practices of PCB Assembly Vendor

Selecting the professional PCB assembly company at the beginning determines the success of a project. Therefore, picking the right PCB assembly services provider becomes a highly important decision to be made. One must watch out for those offering very low prices, but subsequently are unable to provide the services, record of accomplishment, infrastructure, and technology to back up their promises. Rather, one must insist the PCB assembly services have the essential features, offer the services, and follow business practices such as:

Instant Quotations

Waiting for days or weeks and trading a bunch of emails only to find out the cost of a PCB assembly, is not only a waste of time, it is expensive. A vendor offering instant, online quotations is always preferable. In general, although all vendors will start by sending a quotation for the project, therefore, selecting one who gets the process off painlessly is advisable. Moreover, selecting the vendor who gives an estimate in terms of quantity offtake helps in determining capital needs and product prices.

Prototyping Requirements

Most customers, before placing their order, want to make sure their PCB works exactly as intended. This may require making a few iterations to perfect the design. So far, prototyping was a big challenge under the old manufacturing model. However, Best Technology is willing to handle even a single quantity.

Minimum Order Requirements

Earlier, PCB assembly services were unable to accept production runs of small quantities. Older technology did not allow profitability in smaller numbers, which turned out to be a major challenge for everyone. However, use of modern technologies allows easy combination of small orders into larger ones, while switching from one task to another is no longer a major hurdle. Therefore, professional PCB assembly providers accept all types of order, regardless of quantity, and execute them at reasonable prices.

Seamless Manufacturing

With advancement in PCB assembly technologies, it is no longer necessary to track multiple vendors and suffer long lead times. A modern PCB assembly solution such as the Best Technology, offers a platform to resolve any assembly problems, online and from anywhere and takes over the sourcing, purchasing, and assembly of the components. With this approach, the product can be expected to be available in days.

Looking Beyond PCB Assembly

The PCB happens to be only the first step of the many for most inventions and products and PCB Assembly is an especially non-negligible process. Quality can only be assured by finding a reliable company.

3 Defects of Putting Nitrogen into Reflow Oven

Wednesday, January 9th, 2019

We have talked a lot about the defects of putting nitrogen into reflow oven before. Thus, today Best Technology would like to discuss some defects of putting nitrogen in to the reflow oven with you.

reflow oven

reflow oven

√ Nitrogen is very expensive.

√ If the heating effect is better, there will be tombstone effect happening on the resistance and capacitor. This effect is beneficial to most of components, but it will deteriorate the tombstone effect of the small chip.

√ Besides, the nitrogen will also increase the wicking effect of soldering tin, allowing the soldering paste along the fillet weld of the components to climb to a higher place. Maybe it is good for some fillet weld of components, but it is not friendly for some connectors. Because the fillet weld of connectors is the connected to other components. It will cause other problems if tin flows into these connections. What’s more, it will lead to short circuit if the tin climb to a higher place as the fillet welds of connectors are very closely.

5 Benefits of Putting Nitrogen into Reflow Oven

Monday, January 7th, 2019

The reflow oven is one of the indispensable equipments in SMT. Putting the PCB with components goes through the reflow oven then the solder paste adhering on the printed circuit board will melt. After the solder paste getting cold, the components will adhere to the PCB stably.

Picture of reflow oven

After you have learned something about reflow oven, have you ever know how to make the reflow oven work better? Here are 3 benefits of putting nitrogen into reflow oven listed as following:

√ It is able to make the surface tension of solder paste get smaller which is good for the components adhering to the PCB more easily.

√ It can decrease the oxidization in a certain. Because the nitrogen is a kind of inert gas which is hard to produce chemical compound.

√ Reducing the rate of void. Because the rate of void decreases with oxidation.

√ Nowadays, some manufacturers also develop to put nitrogen in wave soldering oven. It is able to decrease the speed of oxidation of liquid tin in the bath. As the slag of tin will be formed when the liquid tin contacts with air. After that, the slag of tin will adhere on the printed circuit board. If it happens to the connect between two spots of tin, it will cause short circuit.

√ It can increase the rate of tin feeding of pin components and then they will combine with the printed circuit board firmly.

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.

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.
