Manufacturing Printed Circuit Boards for Telecommunications
Printed circuit boards play a critical role in our advanced age of information technology, and telecommunications has become nearly synonymous with the PCBs that power them.
The world has come a long way since the age of telephone operators where people would line rows of desks connecting one call to another. Today, the Bureau of Labor Statistics estimates that just 5,000 workers in the United States are still classified as telephone operators, with many of these jobs expected to disappear in the coming decades.
The functionality of massive switchboards has followed the trend of virtually all consumer electronics: miniaturization. Calls and communications can now be placed across the world with little delay thanks to cell towers, satellites, and servers latticing the globe. Yet the speed at which we can communicate takes a tremendous amount of processing power – thus, the PCBs that power telecommunications must be reliable, durable, and above all else, functional.
Printed Circuit Boards and Telecommunications
With the diverse methods with which we stay in communication with one another, printed circuit boards play a critical part in our day-to-day lives. Some of the many applications of telecommunications PCBs include:
Voice over Internet Protocol (VoIP) Devices
Electronic Data Storage Devices
PBX Systems
Wireless Communication Systems
Mobile Phone Tower Systems
Satellite Systems
Digital and Analog Broadcast Systems
High-Speed Servers & Routers
With so many different applications, it might seem impossible to summarize the similarities that telecommunications PCBs share.
However, some generalizations can be made.
First, many telecommunications printed circuit boards need to operate in extreme temperatures. Cell towers and satellites are often subject to extreme fluctuations in temperature, and printed circuit boards for these applications must account for these conditions or risk operational failure.
Second, these boards need to be able to deliver signals without distortion. Telecommunications printed circuit boards are subject to a higher degree of noise influences and conflicting signals, and as boards continue to grow smaller, signals have a greater likelihood of distortion.
Finally, these printed circuit boards often must fit in unconventional spaces. From satellites to wearable technology, the shapes that these boards must fit within may not be a traditional square that you might typically find. They may also be subject to heavy vibrations, and cannot rely on rigid forms.
With these constraints in mind, we now turn to how printed circuit board designers and manufacturers go about solving these issues to ensure a clear, fast, and reliable signal in the devices that connect the world.
Problems Printed Circuit Boards Must Address in Telecommunications
How does a printed circuit board in telecommunications go from design to execution? PCB experts generally start with the end in mind. What conditions will a printed circuit board operate in? By considering the most extreme applications that a board must handle, the design can expand outward from there.
Software vs. Hardware
One initial consideration that needs to be made when manufacturing printed circuit boards for telecommunications is the amount of hardware you want to include in a design. Weight is critical in PCB manufacturing as miniaturization has taken over the field.
Overreliance on software to fulfill components that can be accomplished through hardware can make networks more susceptible to security risks. Hardware components are easier to debug, work with analog signals, and crucially, are less likely to fail. However, hardware can’t be updated, is harder to troubleshoot when it fails, can cost more materially, and take up more space.
As we will see, the conditions that printed circuit boards need to tolerate can often be extreme, and many PCBs for telecommunications need to be placed in small or oddly shaped compartments. The PCB design is thus constrained not only by its ability to operate but by the space and conditions of its operating environment.
Material Selection
Most boards are manufactured using a standard FR-4 material consisting of glass fiber and epoxy, which is laminated with copper foil. While these boards have good heat resistance and nearly no water absorption, they aren’t designed for the high-temperature PCB applications that many telecom PCBs need to operate properly.
