WiFi PCB | The Ultimate FAQ Guide

A WiFi PCB is has a vital role in powering WiFi technology. To power up WiFi-enabled IoT devices, you need WiFi PCBs inside them. Printed Circuit Boards or PCBs are the powerhouses of electronics. Hence, circuit boards that enable WiFi tech are called WiFi PCBs.

Here are the core facts about WiFi PCBs.

We will deck this FAQ article with many questions and corresponding answers to enlighten you about the topic.

You may have a lot of questions about this type of PCB. So let’s go answer them.

What Is WiFi PCB?

WiFi is a wireless communication technology that allows devices to communicate across short distances. Wireless Fidelity (WiFi) is an evolution of the WiFi standard.

Printed circuit boards (PCBs) are boards that provide mechanical and electrical support for electronic devices. PCBs are equipped with circuitry to develop and use circuits on the board.

As a result, WiFi PCBs are those that have WiFi technology to guarantee the wireless connection between devices.

A WiFi PCB

PCBs use many components, such as capacitors, inductors, resistors, transformers, and etc. PCBs use these parts to achieve various functions. Additionally, the WiFi PCB also utilizes antennae to receive the radiofrequency.

Lastly, WiFi PCBs carry energy from the power supply to the components via the conductive traces spread over the circuit board.

How Does WiFi Work?

Primarily, the WiFi technology works based on the use of radio frequency. Radiofrequency emitted by electronic devices enables the transmission of signals among the devices.  We can say that the devices talk to each other using radiofrequency.

The other vital parts of WiFi communication are the antenna and router.

The radiofrequency is the signal, while the antenna is the receiver of the signals on the routers. Then, routers then pass the signal to the devices to connect them to each other.

A Hertz is the unit of the frequency. Unlike conventional wireless communications, WiFi uses Gigahertz (GHz) range of frequency instead of KHz and MHz.

WiFi Distributes Connections Wirelessly

Consider the motion of the waves on the ocean. Wave after wave follows one another, and you might think of them as having the same frequency. In the case of radio frequency, the waves go through billions of cycles in a single second.

This is the rationale why you must configure the WiFi receiver to a particular frequency to receive the frequency.

The WiFi network operates at frequencies ranging from 2.4GHz to 5GHz. To be more exact, the WiFi Router  PCB broadcast data in a frequency ranging from 2.412 GHz to 2.472 GHz.

Here is an elaboration on how WiFi works. Watch the following video.

WiFi PCB Implements Wireless Connections

What Are the WiFi Transmitter & the WiFi Receiver?

WiFi Transmitter

The WiFI PCB’s purpose is to transfer data to WiFi-enabled devices. The WiFi transmitter is in charge of sending WiFi signals to your devices.

The radio waves are passed via the antenna by the WiFi transmitter. The transmitter has a transmitting antenna built-in.

A transmitter’s primary function is to create a carrier wave. The WiFi router’s adaptor converts the data into an electrical pulse. The pulse has a waveform as well. The combined data is now sent via the WiFi network to the receiver.

Wireless Receiver & Transmitter Pair

WiFi Receiver

Simply, the WiFi receivers get the radio signal from the router’s transmitter in your device. The radiofrequency passes through the built-in antenna to the receiving apparatus.

The metal conductor of the receiver then receives the electronic pulse waveform from the transmitter. Then the receiver adapter converts the electronic pulses into data and serves them to the devices as WiFi internet.

What is WiFi PCB Antenna? What Are WiFi PCB Antenna Types?

WiFi PCB antennas are among the most critical parts of the wireless network. The antenna transmits the receivers’ audio, video, voice, and texts. The receivers might be routers or smart devices.

Mainly, the wireless antenna facilitates the wireless network. All WiFi devices have built-in antennae inside them to receive the radio signals.

In terms of directions, antennae are mainly two types: directional and omnidirectional.

WiFi PCB Antenna

Directional Antenna

The term refers to the directional antenna’s function. For point-to-point networks, this type of antenna is applicable. It just works by transmitting signals in one direction. Directional antennas operate in a narrow, limited region.

Its action can be compared to a flashlight, exposing one small area at a time. Yagi, mini panel, panel, and parabolic grid antenna are different directional antennas.

Omnidirectional Antenna

The omnidirectional antenna, unlike the directional antennae, has a 360-degree range of operation. This type of antenna covers a wider range of applications and offer single- to multi-direction networks.

The omnidirectional antenna functions similarly to a light bulb in your home, emitting light in all directions. Outdoor Omni-antennas, ceiling dome antennas, and rubber duck antennas are the three omnidirectional antennas.

How Do You Make a WiFi Circuit Board?

Anything in electronics starts with a diagram. And then, the rest of the procedures take place. We will be showing you the step-by-step process of making a WiFi PCB for the rest of the FAQ sections.

Drawing the Schematic

Before, we mentioned that the diagram is the first step of making a WiFi circuit board. The next step is the PCB schematic diagram. You draw it or design it with software such as Eagle or Kicad. This diagram will provide visualization of placing components, conductive traces, and necessary orientations.

Designing The PCB Layout

After drawing the schematic of your WiFi PCB, you have the basic shape of your PCB in your hand. Now, the time is to design the PCB layout. You need to import the SchDoc file into your designing tool and create the main layout of your PCB.

You will need to do this based on the schematic of the PCB.

PCB Layout Design in Computer Software

Printing The Layout On The Board

After designing the PCB layout, the next step is to print the PCB design on the physical printed circuit board. Before this, you have to make the PCB board from suitable PCB materials based on your needs.

Etching Conductive Traces

Now your printed board is ready for the next process. The following procedure is to etch the conductive traces on the board. The conductive traces will conduct and flow the electric current to the components you use on your WiFi PCB.

Etching traces have different techniques. You can use chemical etching, or you can use 3D printing or laser printing on your PCB to etch the traces.

Let’s check how a laser prints and etches a PCB.

Coating The Board

After etching the traces, you need to apply conformal coating on your PCBs. Conformal coating is the process of encapsulation of the board, which will protect your PCB from corrosion.

Also, surface finish and other types of laminations are among the protective steps of PCB production.

Before coating the boards, you need to complete the drilling and routing process.

Placing the Components

Now, the WiFi PCB board is ready for assembly. Place all necessary components on the right place of your PCB board adequately based on the layout design. Solder them with the highest care so that no soldering accidents happen.

Maintain a safe distance between analog and digital components. You may also utilize SMT technology or Press-fit PCB technology to assemble the parts in addition to through-hole soldering.

Finally, your WiFi PCB is now ready for real-world usage!

What Is the Dielectric Loss Tangent in WiFi PCB?

In the WiFi PCBs, the dielectric loss tangent(tan (δ) is the measurement of the loss of the signals. The loss tangent is not dimensional. It is also known as the dissipation factor, loss angle, tan, and loss factor.

Loss Tangent Factor

Dielectric loss tangent is proportional to the PCB material used in the WiFi PCBs. If the loss tangent remains low, the PCB material’s power loss will likewise be minimal.

Typically, the dielectric loss tangent has a range of 0.02 to 0.001. The loss tangent has a direct effect on analog signals.

What Is the Importance of Impedance Matching in WiFi PCB?

When high-frequency current travels through the WiFi PCB traces, the combination of capacitance and inductance is called the impedance. Impedance matching is the process of matching the capacitance and inductance parameters. The matched or controlled impedance ensures that radio signals pass through the traces without interruption.

The object of the matching impedance is to transmit the signal device from the transmitting device to the receiving device. So, the impedance must be matched to ensure uninterrupted signal flows.

You must take special care during the PCB layout design to ensure the controlled impedance.

How Do Thermal States Impact WiFi PCB Material Selection?

The thermal characteristics of the WiFi PCB materials play the most vital role when the PCBs perform. The following thermal states play different roles for the PCB substrate.

Glass Transition Temperature – Tg

Your WiFi PCB substrate will be softened in a specific range of temperature. It will go back to its previous condition when you remove the temperature from the PCB. This is called the glass transition temperature of the PCB material.

PCB building materials used for WiFi PCB should accommodate High Tg.

Decomposition Temperature

In decomposition temperature, the WiFi PCB materials get softened, and the impact is permanent. You will see that the PCB materials lose around 5% of the total mass during this process. The temperature when this occurs is the decomposition temperature.

The decomposition temperature range for the FR4 substrate is above 250° Celsius, and the Tg is between 250° Celsius.

How Can Overheat Harm Your WiFi PCB?

We already know about the role of temperatures in WiFi PCBs. So, heat has a significant role on the WiFi PCBs in terms of physical and performance states. High heat is always harmful to PCB substrates. The consequences of the high heat might be as follows:

• An inconsistent coefficient of thermal expansion happens due to high heat. The excessive heat causes structural loss of the WiFi PCB board. It damages the PCB’s physical integrity.
• High heat causes circuit damage to the WiFi PCBs. Once it happens, the circuit will be unable to transmit frequencies.
• The layers of multilayer WiFi PCBs will warp due to high heat. This will disrupt the PCB thickness, width, and length.
• High temperature causes oxidation to WiFi PCB materials. Lastly, the exposed material loses its preventive oxidation capability too.

Proper Coefficient of Thermal Expansion Essential for PCB Physical Structure Sustainability

What Steps Should You Take to Prevent High Heat on Your WiFi PCB?

You should take the following steps to protect your WiFi PCBs from the high heat.

• Use a heatsink. Place the heatsink properly.
• Use proper conformal coating.
