The Ultra-wide Band 5G FPC

5G FPC

Since the invention of 5G, the future of high-speed communication and connection has never looked brighter. Moreover, manufacturers are trying their best to utilize this technology in the best way possible by finding multiple application areas of 5G in various industries. One industry hit by the 5G trend recently is the PCB industry via 5G flexible printed circuits.

5G flexible printed circuits promise impeccable speeds and more efficiency. However, are these reasons sufficient to encourage a switch to this technology? And if so, are there more advantages of utilizing 5G FPC in your projects?

FPCs in a Nutshell

Flexible Printed Circuits which also go by the terms flex circuit and flexible PCBs are simply PCBs that can bend. FPCs are typically made of a slim insulating polymer encompassing traces of conductive components that create the board’s circuit. Flexible printed circuit boards have been around since the 2nd world war. And even though these circuit boards have been around for a long time, they are still prevalent in the tech industry.

FPCs are most popular due to their folding, bending, thin thickness, and lightweight properties, making them great for multiple applications. Moreover, with the growth in the electronics industry, technicians are finding more ways to make the board design of FPCs more efficient and high precision. Moreover, they are also incorporating new technology (5G) to make these circuit boards more efficient and reliable.

Types of Flexible Printed Circuit Boards

Flexible Printed Circuits come in many different variations according to their design. However, here are the main types of FPC that you can find in the market today:

Single Sided FPCs

Single Sided FPCs are typically the most popular flex circuit boards in the market today. These circuits encompass one layer of copper traces present on the dielectric layer. Moreover, the dielectric that technicians utilize on these circuit boards is typically polyimide. They also add a single polyimide overlay onto the circuit for insulation purposes. Moreover, the polyimide overlay also shields the circuit board from external environment degradation.

Double Sided FPCs

Double-sided FPCs are simply flexible circuit boards that have multiple layers on either side of the dielectric layer. To make a connection, technicians simply plate the layers by metalizing them through holes.

Multi-layer FPCs

Multi-layer FPCs have a couple of copper layers effectively separated by multiple dielectric layers. However, these copper layers are then connected via through holes.

These FPCs bear incredibly complex interconnections and layer designs. Therefore, they are the most challenging FPC to produce.

Rigid Flex FPCs

Rigid-flexible circuits are simply PCBs that contain many circuit layers which are connected via a pre-preg bonding film. Generally, from their physical appearance, these circuit boards are a combo of flexible circuits and rigid PCBs.

Rigid-flexible PCBs have a higher element density.

5G Flexible Printed Circuits

Full PCB Manufacturing

5G is simply the 5th gen tech of mobile broadband. Moreover, this technology exists in three different variations:

  • High band
  • Mid band
  • Low band

5G hasn’t been in the industry for long; however, it has been a force to reckon with since it hit the industry.

Technically, 5G utilizes cell sites divided into several units that send encoded information in the form of radio waves via wireless and wired connections.

When compared to 4th Gen tech, 5G offers:

High Speed

Since 5G has a more significant channel, it tends to transmit information much faster when compared to 4G. Moreover, instead of using 4G’s 1GBps to share information, 5G can reach a peak speed of up to 20GBps.

Lower Latency

5th gen networks, as of now, are mmWave or sub-6 GHz, which makes them more efficient and responsive when compared to 4G. Moreover, this feature improves the UX (user experience) immensely and permits this tech to be utilized in applications and sectors with more robust demands.

Increased Connectivity

The reduced latency and increased speed of 5G generate a more prominent connection which ultimately opens fifth gen-enabled gadgets to enhanced cloud software, sensors and intelligent devices, and machine learning tools.

Better Reach

5G technology offers enhanced reach of cellular to WIFI roaming and communication. Moreover, this tech can reach even remote areas that do not have digital connections, bringing critical tech to various communities.

5G Flexible Printed Circuit Boards

The connection improvements that come with 5G technology alter the landscape design of 5G FPCs. As fifth gen tech becomes more popular, demand for this tech in the PCB industry increases, raising the standards for adaptable FPC designs.

While 4G FCPs utilize baseband units, fiber optics, copper wires, remote radio units, and antennas, 5G FCPs have decentralized and centralized units with mobile edge computing and broadband control units.

Moreover, 5G FPCs need increased base stations since more antennas and coverage are necessary.

Flexible printed circuit board manufacturers and designers cannot afford to ignore fifth-generation tech since it is gaining popularity quickly. Moreover, experts expect this technology to affect all areas of the manufacturing process, i.e.:

Customer Awareness

 With the growing popularity of 5G in the PCB industries, clients are bound to know about this technology. Therefore, manufacturers without this type of FCP or the technology to build them might lose customers.

Therefore, to stay caught up, manufacturers are adapting processes and technologies that lead to the development of 5G FPCs.

Data Traffic

By 2024, experts predict that 5G will be handling up to a quarter of mobile data traffic worldwide due to its :

  • Reliability
  • Versatility
  • Low latency
  • Speed

Therefore, not adapting 5G technology into your FPC production process could lead to you gaining immense losses in the coming years.

How does 5G Affect FPC Production?

Since the emergence of 5G technology, FPC manufacturers have been trying their best to incorporate this tech into their production process by adjusting their FPC designs and production process. However, using 5G tech has led these manufacturers to make the following alterations:

  • Produce smaller design – flexible 5G circuit boards provide impeccable reliability and fit into innovations such as foldable phones.
  • Thinner traces – manufacturers can utilize mSAP (semi-additive fabrication process) on 5G FPCs to generate straighter, more accurate traces for impeccable circuit density.

Conclusion

Flexible Printed circuit boards are, without a doubt, a marvel of engineering. Their ability to fold helps manufacturers produce more compact and efficient gadgets without compromising the device’s efficiency. However, with the addition of 5G functionalities to these circuit boards, their efficiency has increased, and now they are more powerful and efficient. And since 5G is just being realized, you can expect to encounter more advances in this tech. We hope that this article has provided you with all the answers that you were looking for regarding 5G FPCs.
