Microwave PCB: The Ultimate FAQ Guide
Microwave PCBs are unlike standard PCBs because they operate on the Radio Frequency (RF). Do you want to know more about microwave PCB? You will read this guide.
This article lays out a number of recommendations and criteria to keep in mind while designing and selecting Microwave PCBs for certain purposes.
Microwave PCBs come in a variety of shapes and sizes. A full explanation is provided further down in this text. As a PCB hobbyist, we strive to provide you with accurate information.
PCB is the building block of almost all electronic devices.
A printed circuit board is used to mechanically support all the electronic components present on the board and connect them electronically using conductive pathways.
In a printed circuit, board all the electronic components and conductors are contained within a structure.
The printed circuit board is built by alternating conducting copper layers along with layers of insulation material.
Copper layers of the printed circuit board are etched leaving traces of copper to connect circuit components during its manufacturing.
The copper layers are laminated once they are etched, and then a printed circuit board is completed.
Printed circuit boards are most commonly present in computers but apart from that, they are present in other electric devices like TVs, remotes, digital cameras, cell phones, microwaves, medical devices, etc. There are many types of PCBs such as
A normal PCB
Microwave PCBs are a special and modern type of PCBs.
They contain components that are used to carry microwave signals. They are designed to operate on the signals of megahertz to gigahertz frequency ranges.
They are the best and most common PCBs in the electronic industry that are highly recognized for their ability to carry higher frequencies as compared to the other circuit boards.
Megahertz is a medium-range frequency whereas Gigahertz is an extremely high-range frequency.
These frequency ranges have vast usage ranging from smartphones to military radars.
Microwave Printed Circuit Boards are made of materials pressed and bonded together to make layers.
The top and bottom layers will have a majority of the electrical components mounted on them. Connections are made between components are trace using wire bonding.
The composition of the layers greatly affects the performance of the Microwave Printed Circuit Board.
Very specific materials and technology are used to make these PCBs. These technologies are not present in every industry.
A microwave Printed Circuit Board
A microwave printed circuit board design is creating a scheme or a layout as provided by the hardware team.
There are many things in creating a microwave printed circuit board design. From a basic printed board to a non-rigid PCB
- A layout is created on a bare board. In addition, make a list of the components of a microwave printed circuit board.
You need to learn that what components are required in your microwave printed circuit board. How you can connect them.
What is the relationship between different components of your scheme?
- When a scheme is ready, place the components as per the flow of the scheme.
- Insert the drill holes in a microwave printed circuit board
- Trace all the routes that are connecting between different components.
- Make sure to add tags and identifiers of different components.
- In the end, make files of your microwave printed circuit board design.
Microwave PCB Design
If you need to know more about microwave PCB, please have a look at this video:
There is a considerable difference between RF and microwave PCB. RF is a radio frequency, a signal with a very high frequency.
RF circuits’ high frequency creates sufficient PCB solutions in manufacturing and operations
The RF frequency range is typically from 500 MHZ to 2GHZ and designs above 100MHZ are considered RF. Which is quite understandable.
In electronic industries, there is a high demand for RF PCB.
They are widely using RF circuit boards to run their business operations, find smart solutions after completing their circuit board design.
Modern technologies are making maximal use of these RF printed circuit boards.
RF PCB is used in different applications like smartphones, TV, remote controls, digital cameras, sensors, etc.
Whereas the microwave frequency range is anything above 2 GHz. This means these circuits only work on high frequencies.
Most of the applications and communications systems use microwave-printed circuit boards.
They are used in radar systems, wireless base stations, and high-performance aerospace applications.
Microwave Printed circuit Boards are a very important part of modern electronic equipment and have exclusive benefits that include
- Extreme high stability:
These microwave PCBs have the ability to withstand high temperatures and show extreme stability.
Compact sized:
On a printed circuit board, a larger number of electric components are present. These components are connected to each other through copper tracks instead of using a large number of current-carrying wires.
These connections make the circuit board less messy.
A microwave circuit board makes it very easy to arrange many electric components on a board in a compressive and very efficient way.
Microwave PCB
These components are very small in size and it would not be possible to connect them through wires without using a printed circuit board.
Cost-effective:
These circuit boards are usually less costly since the components used are cheap and readily available. In addition, they cost even less when they are produced in bulk.
Resist movement:
As all the electric components are fixed on the printed circuit board, they are held in their place.
These microwave-printed circuit boards are very sensitive entities.
There can be many issues while designing a high-frequency microwave printed circuit board.
While designing printed circuit boards many things must be considered to avoid the risk of failure, signal disruption, and other distortions. These areas follow:
- While designing a microwave-printed circuit board, avoid using components that are not advised. Either they can be old or discontinued and replaced in near future.
- Components should be spaced and not jumbled up. This can avoid many future problems. Components that are too close to each other can cause assembly and repair problems.
- Avid using expensive components. So when there is a need to replace them, there are no budget problems.
- Avoid making any last-minute changes to the design of the oriented circuit board. It will not update your printed circuit board layout. Instead, it would change it into another design.
- Components must be placed wisely that produce a lot of heat. Chose a location that is best for airflow. Place them away from other components.
- Signal paths must be made properly. Traces that connect high-speed signals should be as short as possible.
- Microwave signals are extremely sensitive to noise. So you need to work to minimize noise and other distortions while you are treating the system with care
Fabrication of a microwave printed circuit board is certainly challenging for the electronic industry.
First, you need to collect all the components required for the assembly of PCB. These are
- Base laminate materials
- Copper foils
- Bond films
- Embedded resistors etc
After all the components are collected on the table, the connections are routed between them.
Once all the components correctly place, circuit simulation is done.
Moreover, it is made sure that the circuit works properly.
The circuit integrity is checked. Any error or fault present in the microwave printed circuit board is rectified.
In addition, it is recommended that you should not change components at the last moment, it might covert to PCB design into another.
Microwave PCB Fabrication
Impedance is the resistance of an electrical circuit or component to alternating current. It is generally measured in Ohms.
Impedance control of microwave printed circuit board is resistant to alternating current that could occur because of both resistance and reactance.
Printed circuit board impedance control has been one of the concerns and challenging problems in high-frequency PCB design.
Impedance affects the schedule on which the printed circuit board completes its function.
By alternating the physical features of the printed circuit board component can help in controlling impedance.
It gives impedance a particular value that helps a circuit work in a way in which it was designed to work.
As a printed circuit board impedance designer, you should know what affects the impedance of PCB. And how you can control and calculate it.
Impedance control is usually a design consideration in the case of high frequency and high-speed printed circuit boards.
A printed circuit board with a controlled impedance will neutralize any changes that are made in the voltage of the circuit.
Thermal conductivity is an important aspect in the case of printed circuit boards.
It is an important physical quantity that measures the rate at which the thermal energy flows from a high thermal region to cooler regions of the materials.
While designing a printed circuit board, thermal management methods should be adopted to keep the temperature of the printed circuit board in a safe range.
You need to use a substrate with lower thermal energy in case your board operates in higher thermal energy.
Safe temperature limits are important to avoid failure in the design of printed circuit boards.
The printed circuit board designers use different techniques through which they can control the thermal conductivity of printed circuit boards.
These include using heat sinks, thick copper traces, fans that keep the board cool, laminated heavy metals, thermally conductive adhesives, etc.
Printed circuit board designers use infrared cameras to detect any heart problems and identify issues that are not usually visible.
In case of the repair of the microwave printed circuit board, you first need to find out the faulty component.
Circuit board testing is a monotonous procedure that is usually done for short circuits.
First, you need to check the transistors of a printed circuit board. Then you should test resistors and inductors because they are less likely to get fail.
Many types of tests could be performed to check the working of microwave printed circuit board components.
The first one is In-circuit testing. It is one of the most important tests to exist.
It has probes that are almost similar to the design of PCB. It is used to check the integrity of
There are the access points in the board that allows the testing probes of in-circuit test to make connections.
When this connection is made, it puts pressure on the connection.
This test allows making sure that the circuit can withstand such pressure and stay put.
Some of the other tests that are used to check the components of microwave printed circuit board is:
Micro-sectioning analysis: It involves the detection of micro defects. Small defects, openings, and failures can be checked through this.
PCB Contamination test: This test detects that contaminants that can cause corrosion of the printed circuit board.
Choosing the right laminate material for microwave PCB is very important. It depends on many factors.
The laminate material holds the layers of printed circuit board together.
The laminate material you should choose must be strong and yet lightweight. So that when it is added to the board, it does not make the printed circuit board heavier in weight.
Microwave PCB
One of the major printed circuit board laminate materials is Polytetrafluoroethylene. It is a high-frequency material.
It is a synthetic thermoplastic fluoropolymer. It is a low-cost polymer with good dielectric properties, tensile strength, fire retardant, etc.
The most common type of microwave printed circuit board lamination is FR 4. It is used most frequently in the electronic industry.
Apart from that, the major printed circuit board laminate materials are
High-performance FR 4, these laminates are best for multilayer printed circuit boards.
Teflon laminate is used in high-frequency boards. And it is used for low-cost communications.
Isola high performance printed circuit board laminate is used in manufacturing copper-clad laminate products.
The environmental factors play a major role in the working of microwave printed circuit boards.
If a printed circuit board designer is making a PCB for outdoor use, he must keep in mind the environmental factors that can affect its normal working.
The major factor that should be kept in mind is the temperature range of the area in which it is installed.
You need to make sure it lies within the temperature range of the printed circuit board.
Dust particles, electric interference, vibrations should be kept in mind while designing a printed circuit board.
Other factors such as thunderstorms, rain, snow, and winds should also be considered and solutions should be made for them.
For such cases, the printed circuit boards used typically have a protective enclosure to protect them from environmental factors. And prevent damages in the design of printed circuit board.
A reliable microwave printed circuit board should possess certain qualities:
- It should resist environmental factors that can interfere with its working.
- The printed circuit board must provide physical and electrical characteristics when working
- Consistency and stability are two properties of a reliable microwave printed circuit board.
- The connections between different components should not be made with wiring, instead, copper traces are used in reliable microwave printed circuit boards.
- The reliable microwave printed circuit board has good thermal managing properties.
- A reliable microwave printed circuit board must have good electric insulating properties.
- It must have the strength to withstand the pressure produced by the connection between components of a printed circuit board
- The laminating material between the layers of a reliable printed circuit board is of good quality and has good properties of adhesion.
Finding a damaged component in your microwave printed circuit board could be tricky and will take a lot of your energy.
First thing first, you need to cut off the power supply to the circuit.
Then you need to look for circuit fuses. In the case of a fuse, you would see there is a broken filament. That shows the damaged location of the circuit.
After that look for physical damages of microwave printed circuit board. That could include the broken connections, broken probes, etc.
Connect the positive probe to the collector and the negative probe to the base of a transistor. The meter should read a few hundred volts in case of an intact microwave printed circuit board.
The microwave PCB thickness depends upon the number of layers of PCB.
The greater the number of layers, the greater the thickness, and the greater the tolerance.
It means that the single-layered PCB has the least thickness.
In comparison, a multi-layer PCB has maximum thickness.
However, the standard PCB thickness is 1.6mm according to the manufacturers.
While designing PCB thickness, there are a lot of factors you need to keep in mind
- Board material
- Number of layers
- Copper thickness
- Environment of PCB
- Type of signal used
All these factors help you design a microwave PCB of standard thickness.
Typically, the thickness is from 0.4mm to 4.0mm, depending on your projects.
The simple way to describe a microwave printed circuit board is that they contain microwave frequencies.
A microwave printed circuit board has a frequency of anything above 1 GHz.
These waves are the same that you use in your microwave oven to cook your food. These microwaves have a vast range of applications.
These are high-speed signals. In addition, they are used to communicate very high bandwidth signals.
Microwave printed circuit board is designed in such a way that they can withstand high temperatures.
So what if the temperature exceeds the temperature limit of the microwave-printed circuit board?
Firstly the material that is used for the designing of microwave PCB should bear high temperature.
It is recommended that you use thick boards. More thermal energy would be required in the case of thick boards to reach high temperatures. If the board is thin everything heats up real quick.
You can also prevent overheating of microwave printed circuit board by installing cooling components in the board such as a cooling fan.
Similarly, heat sinks are made in the microwave printed circuit board to flow the heat away from the circuit.
Normally, there are many microwave materials suppliers such as Rogers, Arlon, Nelco, and Taconic.
Rogers: TC350, 4350B, 4003C, 3003, Kappa 438, RT/duroid 5870, 5850, and 6002.
Taconic: RF-35, RF-53TC, TLX-8,TLX-9
