These days, almost all electronic devices, gadgets, and equipment are exclusively using compact, mini-size PCBs along with small variations. These PCBs incorporate various mini-size SMT components all around the surface of a PCB. Moreover, the BGA technology utilizes an under-side package of IC or pin-outs for connection rather than using the corners of an IC package.
Thus produced an HDI Printed Circuit Board, small size and lightweight dimensions product. The HD interconnects arrange in an array pattern directly under the package, which forms the pin grid. This enables the IC of a BGA to take less area over the surface of a PCB, enhances the performance, and gives more functional features in a PCB.
CTBGA stands for Thin Chip Array BGA. It refers to a type of IC package which is used in many consumer electronic devices. These devices include smartphones, tablets, and portable and wearable miniature devices. This article gives you a detailed insight into the advantages and features of CTBGA, along with its usage and applications.
CTBGA serves as an IC package that helps in making portable consumer devices lightweight and compact. It works similarly to a typical BGA package but has the size of the package and thinner chips. The package of CTBGA generally consists of copper traces, ceramic material, and a solder balls layer over the bottom of a package.
Benefits Of CTBGA (Thin Chip Array Ball Grid Array)
BGA offers various significant benefits which enable it as a popular choice in the electronic industry. Some of those advantages include:
· High Density
Today, various consumer electronic devices require tiny packages with various pins. Because of this feature, engineers invented surface-mount Dual-in-line packages and Pin Grid Arrays that give track lower density. However, manufacturers of PCBs face many challenges. Pin bridging is among them. BGA, however, allows us to overcome this problem as the BGA solder balls provide the appropriate soldering needed for placing the package. Therefore, they place solder balls close to each other. This provides strength to the interconnects and minimizes the PCB footprint. BGA components create high-density interconnections which use the surface of a PCB effectively.
· Reliable Construction
The pins of the PGA package have a fragile and thin structure. Thus, resulting in the bending and damaging of these pins. Whereas, this is not the case with the package of BGA. In the BGA package, the solder balls are incorporated over the solder pads, which enables the network to be more reliable.
· Excellent Performance At High Speeds
In the BGA package, all the soldering balls are placed close to one another, which creates a close connection between components, minimizes signal distortion, and strengthens the interconnections during high-speed tasks. This shows that the network provides greater electrical conduction over high speed.
· Less Component Damage
Unlike PGA, the heating process melts BGA solder balls which enables them to connect with the Print circuit board. This, however, aids in minimizing the risk of component breakdown or damage.
· Reduce Overheating
The packages of BGA contain various thermal networks that dissipate the heat from the ICs. Thus, this effectively minimizes the risk of overheating.
Cons Of CTBGA (Thin Chip Array Ball Grid Array)
BGA also comes with drawbacks, like all other electronic devices. However, the drawbacks include:
· Difficult To Inspect
BGA is basically a tiny material piece that allows the manufacturer to place the die of an IC over it. Because of the tiny size of BGAs, the inspection of soldering joints becomes difficult through visual inspection. However, X-ray machines and advanced microscopes may help in solving this problem.
· Prone To Stress
Circuit boards give flexural stress, which further affects BGA. Though, this stress causes reliability issues.
· Excessively Expensive
The soldering process of BGA packages requires highly expensive equipment. This, however, makes the BGA packages more expensive. Furthermore, manual soldering is used in packaging but in extremely lesser numbers.
All the above-mentioned advantages and features add up in the usage and application of BGAs. Thus, increasing the demand for Ball Grid Array packages. Though BGA devices use advanced types of technologies, they are skeptical of failures. Therefore, inspection of every joint on the board minimizes the process of rework. If you are thinking of incorporating BGA into your device. Then choose trustworthy, reliable, and industry-leading manufacturers. Various companies offer a vast range of customizable BGA packages.
Applications of CTBGA (Thin Chip Array Ball Grid Array)
Various consumer electronic devices use CTBGA technology. These consumer devices include smartphones, wearable devices, and tablets. Some common usage and applications of CTBGA technology include:
· Mobile Devices
Because of the higher pin count and small size of CTBGA, manufacturers tend to use them in devices like tablets and smartphones. Moreover, applications like memory, processing, and connectivity also employ this technology.
· Wearable Devices
Wearable devices like fitness trackers and smartwatches use a wide range of CT BGA packages because of their low consumption of power and compact size.
· Consumer Electronics
Consumer Electronics like digital cameras, gaming consoles, and MP3 use CTBGA packages in them. This happens because of their cost-effectiveness and higher pin count.
· Automotive Electronics
Automotive electronics like infotainment systems and engine control systems also employ CTBGA advanced packages. This, however, happens because of their high thermal conduction and high-reliability features.
· Medical Devices
Because of the higher pin count and small size, many manufacturers use CTBGA in medical devices. However, these devices include diagnostic equipment and portable medical devices.
Conclusion
CTBGA stands for Thin Chip Array BGA acts as an advanced IC packaging. It is widely used in consumer electronic devices, which include tablets, smartphones, and mini-portable devices. Additionally, it offers various benefits and features.
These features include high thermal conduction, higher pin count, high reliability, small size, and low cost of manufacturing. Generally, The advanced CTBGA packaging is commonly utilized in wearable devices, medical devices, automotive electronics, and consumer electronics.
