5G PCB: The Ultimate FAQ Guide

With the deployment of 5G technology, probably many companies are in search of high quality and reliable 5G PCBs.

It is for this reason that this guide explores everything you need to know about 5G PCB – from features, specification, properties to structure, just to mention a few.

What Are The Design Considerations For 5G PCB?

 5G PCB

5G PCB

  • Automatic Inspection: the 5G PCB can be termed as a high frequency application and therefore needs to undergo automatic inspection procedures.

The two procedures are the perforated procedure through the Automatic Test Equipment and the optical procedure.

Which enable the product quality to be increased tremendously.

These tests tend to expose the inefficiencies and the possible errors that the 5G PCB may encounter.

They also save time and the lower the costs that come with manual testing and verification.

  • Settle for Low dielectric constant materials (Dk): An increase in the frequency of a 5G PCB leads to dielectric constant losses, it is advisable to use materials containing the lowest dielectric constants.
  • Signal Integrity: High frequencies in the 5G PCBs are a very big challenge.

Thinner tracks can be used to maximize input and output of the PCB though it leads to signal degradation thus more losses.

Such losses impact the Radio Frequency signal transmission eventually disrupting the general signal transmission chain.

These limitations can be addressed by applying Semi-Additive Fabrication Process (mSAP) which enables creation of high precision traces.

  • Using little Solder mask: A large number of solder masks in use have the capacity to absorb a very huge amount of moisture.

This circuit will experience extremely high losses in the event that this happens.

  • Copper traces and plans should be smooth: the 5G PCB frequency is inversely proportional to the skin depth of the current.

This means that it is shallow on high frequency PCB boards.

The current experiences an irregular path if the copper surface is irregular. This raises the resistive losses.

What Are The EMI Challenges In 5G PCBs?

Some of the main complications experienced in 5G PCB boards are Electro-Magnetic Induction (EMI) and cross talk.

An immediate solution is separating the traces in order to address the EMI and cross talk that analog and digital frequencies will bring about on the board.

Versatility can be achieved by using multilayer boards to place high speed traces.

This will ensure that digital and analogue return signals don’t meet while also separating AC and DC circuits.

The natural EMI can also be reduced by including shielding and filters during components layout.

Advanced Automated Optical Inspection systems (AOIs) and 2D metrology are used to ensure that the copper surface contains no flaws, opens or shorts.

Such technological tests assist in identifying risks brought about by signal degradation during fabrication.

What Is A 5G PCB?

This is PCB that uses the 5G technology to transmits signals at very high speeds and extremely high frequencies.

These PCBs operate at frequencies as high as 26GHz, 30GHz and 77GHz determined by PCB application.

This makes 5G PCB almost 10 times faster than 4G PCBs.

The aim is to attain transmission rates of 10-20 times higher than this with a data capacity 100 times higher with a latency of 1 millisecond.

How Does A 5G PCB Compare To 4G PCB?

Compared to 4G PCBs, the 5G PCB offers:

  • Increased Connectivity: the low latency and the very fast speeds of 5G PCBs build up a very solid connection.

This enables devices using 5G PCBs to cloud software, sensors and tools that assist in machine-learning.

  • High Speeds: 5G PCB technology contains more channels than 4G PCB therefore making it faster in user request response.

Unlike the 4Gs 1Gbps peak speed, the 5G PCB at maximum speed can attain an estimated 20Gbps.

  • Better Reach: compared to 4G, it has a very improved connectivity reach in terms of cellular to Wi-Fi roaming and general communication.

Remote areas previously unreachable by digital connections can be accessed by 5G networks.

  • Lower Latency: the fact that 5G networks under 6 mm Wave makes them more responsive than 4G networks.

The user experience is greatly improved and reliability is assured in industries using the network.

What Are The PCB Manufacturing Changes Due To 5G PCB?

The few changes that the 5G PCB has brought in manufacturing and need to accounted for by the manufacturer include:

  • Thinner Traces: most devices using 5G need high-density interconnect PCBs (HDI). This is because they can avert delays in transmission and lost signals due to their thinner traces.

Regular PCB boards tend to have crossed tracks on them that would normally affect performance of 5G PCB.

This can be averted by applying the semi-additive fabrication process (mSAP) to attain accurate and straighter traces resulting in very high circuit density.

  • Smaller Designs: electronic devices and gadgets are constantly changing due to increasing innovations and valiant design choices.

Conventional PCBs are too rigid and bulk for powerful more detailed and compact designs thus 5G PCB boards come in handy.

They are thinner and smaller and don’t compromise performance even with improved features.

  • AOI Systems: Automated Optical Inspection Systems are an advanced way of scrutinizing the 5G PCB board for design and manufacturing flaws.

This is done before mass production and is preferred over manual inspection because of its accuracy and to save both time and labor costs.

5G PCBs need more refined AOI systems because of their compact nature to capture very small misalignments.

 What Is An MM Wave In 5G PCB?

This is a wave spectrum found in the 5G PCB that can be classified under a frequency wave of 30-300 GHz.

Its wavelength ranges from 1-10mm.

The mm wave can also be called Very High Frequency (VHF) or Extremely High Frequency (EHF).

The signal strength of the mm wave is heavily susceptible to interference from rain droplets.

This happens when the raindrop size matches that of the mm wave, usually a few inches leading to severe attenuation of the 5G PCB.

Satellite communication is hindered in Geostationary Earth Orbit (GEO), Low Earth Orbit (LEO) and Medium Earth Orbit (MEO).

This occurrence also affects the GPS signals of devices using the 5G PCB with a high bandwidth.

What Are The Thermal Management Challenges In 5G PCBs?

A large amount of heat is generated by the current passing through the 5G PCB when the signal speeds are very high.

The substrate layers together with dielectric materials used in the PCB manufacturing should be able to sufficiently handle the 5G PCB demands for high speed signals.

The effect of excess heat on the board includes warping, peeling of the copper traces and delamination.

Such flaws tend to cause rapid deterioration of the 5G PCB.

Dealing with such temperatures will require a selection of materials that cater for thermal conductivity and coefficients.

A PCB material with efficient ability to transfer heat, a high thermal conductivity and a stable dielectric constant is the most suitable for 5G PCB manufacture.

How Is 5G PCB Board Optimized?

There are certain vital issues that are looked into to minimize signal losses and optimize the 5G PCB board.

They include:

Exploit Proper Keep Outs For Antenna:

For efficient reception and total transmission of power, the traces must be correctly matched with the antenna impedance.

Controlled impedance is provided by the keep outs which also supply the essential clearance for EMI concerns.

ntrolled impedance PCB

Controlled impedance PCB

Material Selection Based On Impedance

The impedance of of the 5G PCB board relies on the layout of the PCB material.

The materials should be properly selected based on the impedance control.

TX/RX Devices Should Have Channel Pads Synchronized

The Transmit and Receive (TX/RX) chips found in 5G PCB boards are very unique because the channel pads contained in them must be aligned with precision for efficient operations.

Tight footprint tolerances ensure are used to manufacture the chips to ensure this.

Method for Calculation of PCB Impedance Should be Accurate

Impedance matching is a very important parameter when it comes to high speed 5G PCB.

The accuracy criteria for the PCB will depend on the impedance calculation of the PCB.

High Pin Components Should Have Ball Grid Arrays (BGA)

Since many 5G PCB boards are very compact and small, BGAs are used to reduce the fan out in them.

Routing guidelines should be strictly observed to achieve this.

What Are The Challenges Of 5G PCB Technology?

There are two major challenges faced by 5G PCB board designs:

Thermal Management

Improved thermal management is required by the 5G PCB boards because of their reduced latency and the power dissipated at high speeds.

Materials used to manufacture the 5G PCB should be able to promote discharge of heat without compromising the performance.

Materials containing low dielectric constant and containing structures for heat dissipation are preferred.

They assist in averting signal loss and prevent breakdowns.

Antenna Box

Extremely High Frequencies (EHF) are used to operate 5G PCB devices meaning an increased number of array antennas and base stations.

A big antenna box is needed to accommodate the several antenna array units (AAU).

Extremely High Frequency

5G PCB designers face a major challenge when Extremely High Frequency has to be applied.

The millimeter waves from the 5G PCB board have motion via line of sight therefore attenuation occurs during bad weather and physical obstructions.

This can be addressed by setting up more base stations to support the 5G Systems. Multiple phased array antennas will have to be set up to aid in beamforming.

High Bandwidth per Channel

For frequencies under 6 GHz, the 5G PCB network would need frequencies of 100MHz and for 6 GHz and beyond, the frequencies will be 400MHz.

Such parameters would materials that contain a high thermal conductivity and low dielectric transmission loss.

The major reason for this is that the Radio Frequency (RF) end has to be mounted on the 5G PCB Board directly.

Applications using 6 GHz and above will require material that will align well with mmW frequency band substrate of the PCB.

What Are The Applications Of 5G PCBs?

Entertainment And Multimedia

Due to its very high frequency speeds, it is now possible to watch live shows and downloads movies faster in devices containing 5G PCBs.

The download speeds can go up to 10Gbps.

Autonomous Driving

Autonomous cars have already been introduced on our roads using the 5G PCBs in their technology.

Such cars can remotely link to traffic signal and interact with other cars using links from the 5G PCB technology.

Objects in proximity can be detected in a fraction of a second and accidents avoided. This is the latency of 5G.

Farming

RFID are smart chips that can be used to monitor the activities and positions of various farm and wild animals.

Smart and advanced technological machines used in the farms can be controlled via 5G PCB links which are very speedy.

Logistics

The routes used in logistics can be optimized giving better track location using the 5G PCB technology.

An efficient geo-location technology enables better visibility into shortcomings experienced on track therefore improving the location intelligence.

Medical Surgery

The 5G PCB technology has enabled doctors to remotely performs surgeries while being miles away from the theatre room.

Telemedicine is gaining popularity in modern hospitals but subject to the network capacity.

Smart Home

Mobile devices use 5G PCB technology to link with smart devices used for control purposes and monitoring in homes.

The 5G fast speed enables live streaming of CCTV footages to remote mobile devices.

How Does The Demand For High-Frequency Boards Increase With 5G PCBs?

The high frequency 5G PCBs efficiently comply with the requirements of material damage prevention.

That is why designers are warming up to it in the manufacture of devices that sustain electromagnetic waves containing a frequency band of more than 1GHz.

Some of the fields already using the high frequency 5G PCBs include:

  • Smart phone antennas
  • Bluetooth terminals
  • Wireless LAN device
  • Servers

There is currently a roll out of futuristic 5G PCB board high-frequency applications in fields of Advanced Driver Assistance Systems (ADAS) and 5G satellite communications.

These fields are expected to have electromagnetic waves containing very high frequency bands.

That is, between 10GHz to 100GHz and shorter electromagnetic wavelengths of 0.001 to 0.01m frequency band.

Technological innovations have increased with the introduction of 5G mobile technology

What Are The 5G PCB Design Challenges?

The design of the 5G PCB boards comes with a variety of challenges including:

EMI Shielding

Parasitic capacitance paired with Electromagnetic Induction and crosstalk are a major design challenge for 5G PCB boards.

The best way to counter these challenges is to have the traces on the board separated by manufacturing using multilayer PCBs.

This ensures a physical distinct separation of the analog and digital signal routes. The AC and DC circuits are also physically separated.

High Bandwidth Per Channel

A normal 4G network uses a bandwidth of 20MHz per channel.

Unlike the 5G PCB devices which need 100MHz frequencies for bandwidths less than 6MHz and 400MHz for anything beyond that.

Such challenges require fabrication using materials that contain a very high thermal conductivity and with reduced dielectric transmission losses.

Thermal Management Challenges

Improved thermal management is required by the 5G PCB boards because of their reduced latency and the power dissipated at high speeds.

Materials used to manufacture the 5G PCB should be able to promote discharge of heat without compromising the performance.

Materials containing low dielectric constant and containing structures for heat dissipation are preferred.

They assist in averting signal loss and prevent breakdowns.

What Are The Frequency Filters Applied In 5G PCBs?

Filters

Filter

Different filter types are applied in 5G PCB technology in order to achieve the required frequencies and signals.

Such filters include but are not limited to:

  • High-pass filters
  • Low-pass filter
  • Band pass filters
  • Band-stop filters

Based on the fact that 5G PCB operate in very high frequency bands, frequency filters require new resonating structures.

This is a very big challenge in the 5G PCB manufacturing industry.

The 5G PCB filter require certain crucial criteria to operate under a wide temperature range that included:

  • Reliability
  • High bandwidth percent
  • Increased rejection
  • High selectivity
  • Small form factor
  • Low insertion loss

Acoustic wave filters are the most widespread structure which includes both bulk acoustic wave and surface acoustic wave.

These filters can however only be used in bandwidths ranging from 2.5 GHz to 6 GHz.

What Is A High-Layer Count (HLC) 5G PCB?

High Layer Count 5G PCB board are PCBs containing 12 or more layers.

They are thicker than conventional PCBs with an extensive panel size and a tiny hole back drilled.

Insertion loss and impedance control are very critical for HLC 5G PCB boards for maximum performance.

Due to their ability to reduce losses, work at high speeds with faster transmission rates, they are considered the best approach for satisfying the 5G PCB demands.

Their size is a constraint thus methods of manufacturing like reliable vias and accurate registration are a major setback.

Types of vias

 However, their signal integrity is well enhanced with proper implementation of raw high frequency.

How Does Subtractive Manufacturing Compare To Additive Manufacturing Of 5G PCBs?

Subtractive (etching) Manufacturing

This method make use of the etch-resist coating found on the copper layer.

It map forms an image using the process of photolithography on the areas of copper that are essential to retain while the unwanted copper is chemically etched away.

This normally results in irregular cross-sections of the traces thus affecting their impedance the 5G PCB signals.

Since they are high in frequency, they will have a higher loss of signal.

Additive (mSAP) Manufacturing

In this manufacturing method, a thin layer of copper is plated on the laminate then the photolithography process done.

After this, plating is done in places where the resist is not available by addition of more copper.

That is the part that makes the process called additive.

After the desired copper thickness is reached, the resist is removed while remnants of thin copper layer between traces is chemically etched away.

Additive vs Subtractive

Trace geometries in subtractive manufacturing of 5G PCBs is defined during etching while the photolithography process defines them in additive manufacturing.

This allows the traces in additive manufacturing to be more precise having straight vertical lines on the sides.

Closer traces are formed because the rectangular cross-sections are very consistent leading to maximum circuit density.

It also enhances the signal integrity, precise impedance control and reduced signal losses.

What Are The Benefits Of Manufacturing 5G PCB In Multilayers?

The several advantages of manufacturing PCBs in multilayers include:

  • Multilayer PCB allows the AC and DC circuits to be physically separated while also separating the high-speed traces on the board.
  • They enable an effective distribution of power on the 5G PCB Board.
  • They allow precise thermal management capabilities on the 5G PCB.
  • The enable 5G PCB boards to operate at extremely high speeds and at full capacity.
  • They enable the supply of high levels of power to 5G devices.

What Is The Importance Of MSAP Process In 5G PCB Manufacture?

Modified Semi Additive Process is a manufacturing technique (also called Additive Process).

Whereby a thin layer of copper is plated on the laminate then a photolithography process done.

The photolithography process ensures that images of the copper area are map-formed.

After this, plating is done in places where the resist is not available by addition of more copper. That is the part that makes the process called additive.

After the desired copper thickness is reached, the resist is removed while remnants of thin copper layer between traces is chemically etched away.

This allows the traces to be more precise having straight vertical lines on the sides.

Closer traces are formed because the rectangular cross-sections are very consistent leading to maximum circuit density.

It also enhances the signal integrity, precise impedance control and reduced signal losses.

How Do Copper Foil Substrates Impact The 5G PCB?

The largest effect on a 5G PCB board is brought by the copper foil substrates.

It has the ability to sustain the functions of insulation and conduction making it very vital in the manufacture of 5G PCB boards.

It contributes around 40-60% of the total 5G PCB manufacturing cost.

They are normally made from various substrates like wood pulp, copper foil and resin.

The major raw material used in the manufacture of the copper foil substrates is copper foil which take up about 30-50 of the total cost.

This means that copper foil prices directly impact the copper foil prices.

Subsequently, changes in prices of copper also affect the price of copper foils. This is highly dependent on the international copper prices.

What Are The Design Considerations For High-Layer Count (HLC) 5G PCB?

To achieve maximum performance levels of 5G PCBs, a few design considerations have to be considered on the high Layer Count PCB:

Skip Vias

One main design challenge during High Layer Count 5G PCB manufacture is to effectively make interconnects within the multiple layers.

Skip vias effectively solve this problem because they can go through the various layers and not make an electrical contact with the layers.

These vias require the highest level of precision and they are therefore laser drilled.

Upgraded Raw Materials

Upgraded raw materials are a requirement for 5G PCB boards because of the high speeds and data rates involved.

Such high speed materials include E-glass fabric and TU862 which is a component of epoxy resin.

The E-glass fabric is often used in 14 layer PCBs because it is a mid-loss material. Another low loss material is the S7439 which is applied in a 10-layer 5G PCB.

In the event that a high-frequency material is required, hydro-carbon based materials such as Aerowave 300 are used.

Layer To Layer Registration

The tolerance of tight layer registration in High Layer Count 5G PCB is very important.

Extreme factors like humidity and temperature can alter the alignment and registration during manufacturing.

The accuracy with which the registration hole is placed also affects the registration and alignment.

Tight registration tolerances can be achieved by calibrating vital equipment and carefully evaluating the process used in the manufacture,

Impedance Control

Traces can easily be converted to transmission lines when signal traces of the 5G PCB propagate high frequency signals.

The signal is always distorted because a specific impedance exists on every point of the signal trace with an impedance difference from one point to another.

Impedance control has to be included in the 5G PCB design in order to maintain the integrity of the signal.

VIPPO/VIA

The 5G PCB board area is often reduced using the VIPPO (Via In Plate Over) process.

Where the hole spacing’s and the holes are narrowed and the wiring density is increased.

The result is a lighter board and reduced board footprint without altering it performance.

This process is very efficient when skip vias are used.

This process is very complicated during manufacturing but produces very accurate and reliable High Layer Count 5G PCBs.
