You can operate any device without a PCB. PCB would be the main source of any electrical device so that it will work properly. A PCB consists of further different components, and BGA is one of them. You design a PCB according to the size of the electronic device. For smaller devices, BGA PCB works perfectly because of its small size.

You will learn more about BGA PCB in further detail.

An insight into working of BGA PCB

A very small circuit that gets mounted on the PCB and helps connect other electrical components on the PCB is known as BGA. BGA stands for Ball Grid Array, an integrated circuit, or you can call it a surface mount device component that comes with no leads.

It further helps in making connections between the PCB and other electronic components that get mounted on it. A BGA consists of solder balls but doesn’t have any lead. A variety of BGAs available so that you can choose one of them according to your need and budget.

Every BGA will have a different number of soldering balls on the circuit and have different features.

Type of BGA PCB to know about

Different types of BGA are available in the market, and the manufacturer will choose the one according to their requirements and the size of the PCB. Let’s talk about the types of BGA in detail now:

Plastic BGA

You might have gotten a hint that this PGA comes with plastic packaging. Yes, the body of this BGA is made up of plastic. If you are looking for a cost-effective BGA, you can consider this option as it has high density but is quite affordable. A plastic BGA consists of OMPAC and GTPAC. The ball counts on a plastic BGA range between 208 to 976 balls.

Tape BGA

If the manufacturer requires a thinner BGA for their PCB, they prefer to get Tape BGA. It is one of the thinnest versions of BGA, but it will provide you with optimum thermal and electrical performance.

Ceramic BGA

A ceramic BGA becomes necessary if the device in which you are going to install it gets operated at extreme temperatures. Yes, a ceramic BGA can handle high temperatures without getting melted. The most common use of ceramic BGA is computer microprocessor chip technology.

Thermally enhanced BGA

The name of the BGA hints at the type and feature you will have if you get a thermally enhanced BGA. Surely it comes with enhanced thermal efficiency.

Flip chip BGA

A flip chip BGA will have solder bumps, and the main use of these chips is to use control chip collapse on the PCB.

Micro BGA

The size of a typical micro BGA would be 0.4mm, but you can get this technology between the size of 0.25mm to 0.3mm. A micro BGA will undoubtedly have an ultra-fine pitch, but it will become a challenge for the engineer working on the PCB design. It is obvious that doing the routing on such a small size BGA will not be a piece of cake for the person working on the project.


Metal BGA

If the substrate base material of a BGA is copper or metal, then it is a metal BGA. This BGA will have more electrical conduction features, and it would be a good option if the device you install it in has higher frequencies above 500 MHz.

Benefits of BGA PCB in the industry

We have talked about the types of BGA above. All of them have got their unique features and properties. There is a long list of reasons you need a BGA on your PCB. Let’s talk about the benefits of BGA PCB now so you will understand its importance in your electronic devices:

Requires less space on PCB

As we have said above that you cannot operate any electronic device without PCB being installed in it. A PCB connects everything so you can use the device. For the small size of devices, a smaller size of PCB would be required, just like a BGA PCB. It doesn’t require much space to get installed on your electronic device.

A BGA will help connect other electronic components to the PCB, and it will not require much space on your PCB, but it is an essential component of your PCB. So the number one of using a BGA on your PCB would be its small size and connecting features.

Higher inter-connectivity between components

To prepare a single PCB, you will have to install a variety of electronic components to it. You will have to connect those components with the PCB; if you don’t connect them perfectly, your PCB won’t work. A BGA will help in connecting those components with your PCB. Yes, high connectivity is a feature of a BGA.

Every type of BGA will have its inter-connectivity level, but surely it will run the current between the components on the PCB smoothly. Therefore, you will have to install it on your PCB if you want all the other electronic components to connect.

Easy soldering on PCB

We have already talked about the construction of a BGA that comes with solder balls on it and no leads. Now the solder balls of the BGA with stencils will get self-aligned and helps the technicians in the soldering process.

BGA will make the work easier for people working on the PCB soldering process. During the BGA ICs soldering process, the solder balls will self-align, and they won’t make the task any harder for them but a little easier and more convenient.

Thermal resistance is low

A BGA IC will have a low thermal resistance because the heat will transfer efficiently from the heat sinks. A thermal paste would be used to dissipate heat even more efficiently. There will be wide spaces between the pads, allowing the technicians to do the soldering easily.

Improved electrical conductivity

The interconnection between the PCB and the BGA will help make a better connection. The electrical conductivity feature of a BGA is quite appealing because it will have good electrical conductivity, and the current will flow without facing any fluctuation.

No broken pins and they don’t bend

The pins of the BGA will not break because of their micro size, and they won’t be bent. So, you won’t have to worry that you might have to replace the BGA on the PCB if their pins bend or break. It won’t be the case, which is why PCB manufacturers prefer using BGAs instead of QFN.

High reliability and functionality

The performance of any device depends on the components that have been installed inside the device. A BGA PCB will have higher reliability because it helps in easy PCB traces routing and layout. It has a higher level of functionality. So, these are the two features that make a BGA PCB even more interesting.

It will reduce the number of PCB layers because you can connect various electronic components on the same PCB. So, getting a BGA PCB will provide you with more efficiency, reliability, and functionality than you won’t get in any other PCB.

Economical BGAs for PCBs with a limited budget

If you have a limited budget but don’t want to compromise on product quality, you can consider BGA PCB. Instead of manufacturing a multilayer PCB, you can manufacture a BGA PCB. As we have mentioned above, using a BGA on a PCB will help decrease the PCB layers. Therefore, it is a considerable option for your limited budget situation.

You also get the option of choosing the BGA according to your budget. There will be some options that are going to be expensive. You need the one that would make your PCB work perfectly without causing budget issues.

You can even cut down more costs by getting a 100-ball BGA. You get the same functionality and reliability but at quite an economical cost. It will also decrease PCB tracing routing and designing costs. So BGA PCB is an economical option when facing budget problems.

Perfect for industry-grade devices

Last but not least benefit of BGA PCB would be that it is a perfect option for industry-grade devices where the temperature might get a little extreme. Yes, an ordinary PCB won’t work in industries because it might melt. This won’t be the case with a BGA PCB.

A BGA PCB will have more resistance against harsh conditions and extreme temperatures. They don’t melt easily but handle the heat. So, most industry-grade device manufacturers prefer to get BGA PCBs for their devices because of their amazing features.

Final Words:

Now you know the types of benefits of BGA PCB. Every larger or smaller electronic device consists of PCB. BGA gets mounted on the PCB so that you can operate your device. BGA will connect other electronic components to the PCB. As a beginner, you might want to get started with a BGA PCB.
