Innovative Communications PCB Assembly Solutions
Among the fastest paced industries nowadays with rapid changes in technologies is the telecommunications industry. Quick and reliable services call for quick action and due to this factor PCBs have become a necessity in the telecommunications sector. From PCBs meant for wide range broadcasting of networks, to the PCBs required for seamless office communications, the printed circuit boards are the backbone behind all electronic communication equipment. Thus, it would be quite hard to imagine different ways of communication, all before advent of present day’s sophisticated communication technologies.
Due to the communication PCB assembly and equipment that is present within, we can easily connect with each other seamlessly, and clearly with more efficiency than ever before. Of course, for enjoying this faster, clear and efficient forms of communication, we would require the right type of printed circuit boards that are ideal for the job.
Some examples of the communications PCBs are:
- Broadband equipment
- Fiber optic multiplexers
- Cell transmission electronics
- Technology for information security
- PBX systems
- Systems for phone switching
- Satellite technology
- Video conferencing equipment
- Voice over internet protocol
- Technologies for space communications
- Signal amplification equipment, etc.
What to Select for communications PCB Assembly?
Applications such as communications and networking are dependent on high frequency Printed Circuit Boards (PCBs). When the organizations of all these sectors begin approaching the manufacturers of PCB for coming with solutions, the manufacturers also recommend vital solutions such as the Radio Frequency (RF) or the microwave PCBs. A lot of reasons are there as to why the PCB manufacturers suggest the PCB assemblies of the communications and networking applications.
Here let’s find a few basic points for the same!
Data and Communications PCB Assembly Solutions
Different corporations pcb manufacture and design the printed circuit board assembles to get dense RF based communication applications. A lot of materials are selected for meeting certain requirements of the equipment. Typically, the recommended specifications for communication PCB assembly are PTFE, fiberglass, higher grade fiber optics and polyimide amongst all others.
Manufacturers typically design micro as well as complex BGA PCB assemblies through plated and surface mounted technologies.
Customized telecommunications equipment requires SMOBC capabilities along with combination of PTH and SMT assemblies. Also, assemblers utilize selective process for wave soldering for ensuring manufacturing precision which is ideal for avoiding damage in components that are finely pitched.
Communications printed circuit board assemblies are produced with different processes such as:
- Soldering lead free
- Soldering that is lead based
- Processes that are RoHS compliant
For communication assemblies’ assemblers employ placement machine programs with effective utilization of different testing procedures for substantiating performance and quality of communication PCB assembly. Accelerated Assemblies are ideal for performing Automated Optical Inspection (AOI) along with In-Circuit and Functional Testing (ICT) for ensuring optimum quality in all communication equipment. The testing criteria can also include, but isn’t only limited to the analysis of DFM, thermal limits, signal integrity and power consistency.
Other services and abilities that are possible for communication PCB assemblies are:
- Box build assemblies
- Mechanical assembly
- Rework/Repair including QFP and BGA
- Vision systems and laser alignment for placement of SMT
- SMT lines auto-calibration
- Conformal coating and potting
- No-clean solder and aqueous chemistry
- Linked, multiple and continuous flowing production lines

Communication PCB Assembly Services by Manufacturers
PCB assemblers for telecommunication industries mainly have an expertise in PCB assembly along with prototyping services. Typically, telecom PCB assembly is available for both the ROHS and leaded specifications. Some specializations are:
Assembly of Surface Mount Technology (SMT): This is cost efficient way of producing lightweight and compact products. As an outcome, it would be suitable for different applications of telecom such as handheld radios, home networking equipment and a lot more.
Thru-hole technology assembly: Thru-hole PCB mounting can be said as older technology that can be time-consuming for completing. However, this leads to stronger bonds present between the circuit boards and components making this ideal for applications with higher durability.
Final assembly and build box: You can turn PCBs in the functioning of prototypes and product with the box build services.
Contract manufacturing: For telecom industry the contract manufacturing typically incudes Hdi PCB , box building, testing and later on final assembly along with drop shipment.
Understanding the Microwave and RF PCB Assemblies
These PCB types are designed for seamlessly operating on medium to extremely high frequencies (megahertz and gigahertz). These have to be constructed through the use of materials of:
- Rogers RO laminates
- FR-4 with High Performance
- Ceramic filled hydrocarbon
- PTFE having woven or the micro glass fibers
The materials are comprised with specific characteristics like low loss tangent, excellent Co-efficient of Thermal Expansion (CTE),= and less dielectric constant (Er).
Microwave and RF advantages for communication PCBs
Design of all such PCB assemblies are required for communications and networking with the use of higher frequency materials that offer a lot of benefits for GHz and MHz applications.
Stable Er and low loss tangent lets high frequency signals travel through PCBs with much faster rate and low impedance.
Materials are able to combine in multilayer board stack-up ensuring reduced costs of PCB assembly, in addition to optimal PCB performance.
PCB structure remains quite stable in environment with high temperatures. When this is used in the analog applications. All these PCBs are able to operate well at 40 GHz.
It is possible to place fine pitch components in the board in an effective way without getting a lot of trouble.
Because of the low use of CTE materials, PCB engineers are simply able to align multiple layers in the printed circuit boards even in complex types of layouts.
The design benefits and features make the RF and microwave PCBs quite ideal for different applications like the cellular phones, radars, military, telecommunications and other computer networking systems.
Hence, it would always be advisable for enquiring about these PCBs when contacting circuit boards manufacturer about PCB assembly for communication and networking applications.
Being involved in communication PCB assembly requires trained staff with years of expertise. Assembly with mixed technology are designed by manufacturers to form solutions for different applications where the combination of surface mount and through hole assemblies would be required. A lot of innovators are ensuring superior quality and value through ensuring ball grid array (BGA) assembly for integrated circuits and lead-free communications PCB assembly.
