It works for rectifiers to filter out the AC component and only keep the DC components. This printed circuit board is a must-have for many electronic devices.
PCBMay is one of the largest manufacturing companies of PCBs situated in China. We strive to provide the best quality printed circuit boards with their best potential.
If you are eager to know all about filter printed circuit boards, this FAQ guide is for you. This ultimate FAQ guide contains all little information about these filter circuit boards.
What Is Filter PCB?
It is a kind of printed circuit board that is able to give control powers to the construct filters. The control power is provided through logical query creation. Filter printed boards are essential to the PCB industry.
You can apply a filter circuit board to an active PCB. This also allows you to select multiple objects at a time. You can as well as edit the objects, not to mention that the selection and editing are done with the best efficiency and accuracy.
What Are The Types Of Filter PCB?
Well, there are various types of filter printed circuit boards available. But there are some that are most commonly used. You need to choose the right type of filter circuit in order to get your work done.
There are four types of primary filter circuit boards that are most common. They are:
- Low pass filter PCB
- High pass filter
- Bandpass filter
- Bandstop filter
Low Pass Filter PCB
We can also categorize filter circuit boards into two categories. They two serve differently. The categories are named as:
- Active filter
- Passive filter
Watch the following video to get a more clear concept.
What Are The Capabilities Of Filter PCB?
In terms of the capabilities of filter printed circuit boards, there is actually a lot to mention. Nowadays the PCB industry widely depends on filter PCB because of what these PCBs are able to perform. There are a lot of services that are actually provided by filter PCB.
The capabilities of filter PCB are mentioned in the following.
- A filter circuit can eliminate unwanted components from any signal.
- Switching power supply is one of the major capabilities of the filter circuit.
- Filter boards can work in applications with high frequency as well as high voltage.
- Filter boards are also capable of maintaining a range of temperatures in the applications.
Envelope Filter PCB
How Do You Select The Components Of Filter PCB?
Selecting the components of a filter PCB is as important. The performance of the printed circuit board largely depends on the component it is made with. So the component selection should be considered wisely.
Capacitors are a very important part of power supply filters boards. The effectiveness of the filter PCB depends on the performance of the capacitor. Especially the ESL and the ESR of the components directly affect the performance of the filter.
If you are looking for general filter boards for applications of power supply, ceramic capacitors can be a good option for you. Ceramic capacitors have the minimum range of ESL and ESR. so it is able to provide the best ripple decrease. You can get these filters in a versatile range of temperatures as well as these capacitors have a long lifespan with the most stable effectiveness.
You may choose a film capacitor if you have a high current necessity in your applications of power supply. Film capacitors are also very small and low budget. But the ESL and ESR rates will be a bit higher, and if there is an over-voltage situation, these filters will be less tolerant to that in comparison to ceramic capacitors.
There is another capacitor which is aluminum electrolytic. They are small in size and cost less as well. They are actually the most used type of capacitor for filter PCBs.
But we need to mention that these capacitors come with higher ESR which may not work so well in high-frequency situations. The capacitor also does not provide a stable performance which means the effectiveness decreases over time. The life span is not as long.
The last type of component is Tantalum capacitors. They provide better services but are not so cost worthy. We even can not use them if we have a high voltage or high-frequency situation in the application which limits their use in power supply systems.
What Are The Applications Of Filter PCB?
There is a wide range of applications of filter PCB in the electronics field. The use of these PCBs is only increasing day by day as most of them are very practical. Some of the major applications of filter printed circuit boards are given below.
● DC Power Supply
We use filter circuits to filter out the unwanted high frequency from the AC line of input. For example, we can eliminate noise from an AC input line using this circuit board. Moreover, we may use these filter boards in order to decrease ripples from the output of a power supply.
● Radio Communication
If we use a filter circuit board in the radio communication system, it works to enable the radio receiver to receive only the wanted signals. It can also work to reject all other sorts of signals. Here it is assumed that the rejected signals have contents of different frequency levels.
● Converting Analog to Digital
Filter circuit boards are able to convert the analog system to a digital one. We place the filter boards before the input of ADC in order to decrease aliasing. It works completely fine.
● Audio Electronics
There is a wide range of uses of filter PCBs in the audio electronics industry. There is a network of filters called a crossover network. The network is able to channel mid-range frequencies and then convert them to midrange speakers, audio with low frequency to woofers as well as sounds with high frequency to tweeters.
Noise filter PCBs are very much useful in audio electronics.

What Are The Advantages Of Filter PCB?
If we want to talk about the advantages of the filter printed circuit boards, it is actually beyond description. The advantages these PCBs provide are mind-blowing. Nowadays the PCB electronics industry can not but serve without filter circuit boards.
The advantages are providing us as follows.
- They are able to detect and amplify certain frequencies. It helps us to work with a lot less hassle.
- The unwanted frequencies can easily be filtered out by filter circuit boards which makes the work a lot easier and a lot less time-consuming.
- We can set a minimum and maximum range of frequencies in a filter PCB as we work with it.
- Important frequencies can be extracted from receiving signals with the help of filter boards.
Filter Circuit Board Advantages
How Does A Filter PCB Work?
We generally need a rectifier to get the supply of pure DC in different electronic circuits. But the rectifier output can be either AC or DC. Generally, we do not need the AC component and it should be redacted in order to keep the process easy.
In that case, an envelope filter PCB can be used in order to filter out the unwanted AC components and only get the DC component in the process. The filter circuit erases the AC component from the output of the rectifier and gets the DC component in our application process. The capacitor and the inductor both work to reduce the AC component and get the DC components.
The filter circuit is placed between the frequency load and the rectifier. The circuit board is a setup of capacitors and inductors. Both of them do the filtering process with their basic principles.
Watch the following video about AC line filter:
How To Design A Filter PCB?
Designing an envelope filter PCB in the right way is very important. Because of the way you design the circuit board, the final output will come exactly like that.
There should be a predetermined layout of the filter circuit board. The design process follows some specific steps. The designing steps are as follows.
● Decide On Signal Bandwidth
Here you should select the minimum and maximum frequency range for the filter. The other except this range will be filtered out. You also need to decide on the dispersion while designing as it selects the dielectric constant.
● Stackup Selection
At this step, you need to figure out the stackup design to make sure the transmission line impedance and the PDN impedance requirement.
● Schematic Capture
When you are done with the schematic preparation, you can capture the design in a blank layout.
● Placing Components
Then you can select the components and the designer can begin to place the components.
● Antenna Placing
You should carefully design the printed elements like antenna structures. Once they are finalized, you can put them on the layout of the PCB. the antenna should have the required characteristics of the signal.
When you are done with the component placed in the layout of the filter PCB, you need to route the design. The routing should be done with consistent transmission line impedance.
● Documentation And Starting Manufacturing
The designing process should be finished with having a standardized deliverable set generated through the process.
What Softwares Can You Use To Design Filter PCB?
The designing process of the filter PCB can be easily done with differing design software. You can select the requirements of your PCB and get a layout and then get the design rules. The design rules must be followed.
Circuit Board Design
The designing software has made the work of the designers a lot easier. The designs can be customized in the software complying with the requirements of the applications.
Altium designers are one of the most used designing software for filter PCBs. It contains all the necessary tools, outlines, layouts in the software. Any designer can easily design the PCB with this software as well as customize it.
How Do You Create A Layout For Filter PCB?
When you are done with designing the stackup of the filter PCB and setting your application requirements, you may proceed with creating the layout for your printed circuit board. There are some specific rules to create the layout of filter PCBs which are as follows.
● Draw The Design
The design needs to be floor planned and the requirements should be put in place for creating the PCB layout. Make sure that any component does not overlap and is placed in the right place. Low pass filter PCB layout is not any exception.
● Use Small Traces
The traces between the printed elements and the components should be short. They should not work like transmission lines in the case of high-frequency PCBs. If you keep the traces long, there are chances that the signal can be sent back among the components.
● Take Care Of Parasitics
If there are parasitics in your PCB design, it may cause a large difference of impedance between the design impedance and the actual impedance. In this case, you need to use several techniques to realize the parasitics. You can use network parameter analysis.
The components should not have parasitics as well. Because it also may react to cause impedance difference at high-frequency conditions. To avoid these problems, you need to be very careful in selecting the inductor and the capacitor.
● Placing Components
The components of the printed circuit board should be placed above the ground plane to ensure isolation. The input impedance should be consistent as well as entering the filter circuit.
Low Pass Filter PCB Layout
What Is The Manufacturing Process Of Filter PCB?
After the designing process is complete and we have the layout of the filter PCB, it is time to start the manufacturing process. The manufacturing process is so important as the whole output depends on it.
The manufacturing process of this PCB is no other than other PCBs. It follows some specific steps which include:
- Printing the layout
- Printing the inner layer copper
- Etching copper from the interior layers
- Aligning layers
- Layers laminating

- Solder mask
- Applying silkscreen
- Finishing the process
- Testing electrical reliability
PCB Manufacturing Process
What Surface Finishes Are Used In Filter PCB?
Surface finish is necessary for filter PCBs as they protect the circuit boards. There are many different types of surface finishes used on filter PCBs. You may choose one of them as your requirement and preference.
PCB Surface Finishes
The most used types of surface finishes on filter PCBs are given below.
What Is The Electromagnetic Compatibility Of Filter PCB?
Well, the electromagnetic compatibility of filter printed circuit boards is great. It is a big concern as electromagnetic radiation works directly for the performance of the EMI filter PCB. The electromagnetic radiation controls the effectiveness of the printed circuit board directly.
EMI Filter PCB
The components of the EMI filter PCB produce and transfer signals which are intentional radiators. The electronic devices that use filter boards do need special attention in the case of high frequencies and high voltage PCBs. The radiator selection among many of them should be accurate in order to get the best electromagnetic compatibility.
How Do You Control Impedance Of Filter PCB?
We need to carefully route the traces of the PCB in between the PCB elements and components to control the impedance of the filter circuit in the layout. The routing is considered the best when they take the design of your PCB stackup. As you route the traces on the layout of the PCB, the tools will provide you with the same impedance profile.
The signal integrity’s main aspect is this in high frequency and high-speed designs. It also makes sure that the structure and circuit have the correct filtering behavior and bandwidth.
Controlling the impedance of filter PCB has a great aspect on filter printed circuit boards. The impedance from the design and the layout should be the same in order to keep the filtering process smooth. Impedance control PCBs are essential here.
You can calculate the PCB impedance control for your circuit board. There are some ways you can follow to control the impedance of the filter circuit board. The ways can be described as follows.
- When you route the traces in the design of your filter in the design software, you should check if the design software has an impedance control system in the designing process.
- The tools in the designing software should have unique techniques in the system. The filtering and the interconnecting structure like electromagnetic bandgap and substrate integrated waveguides structures should be present.
- If the filter PCB design needs to work in ultra high-frequency applications, you can alter the traditional waveguides with systems that provide high isolation and low loss. For example, there are systems like transmission lines that are mode selective.
How Much Does Filter PCB Cost?
Well, there is no fixed price of filter PCBs to be mentioned. The price differs from brand to brand and to different manufacturers. But we can say that the filter printed circuit boards are not that costly.
Cost-Effective Filter Circuit Board
You can customize your printed circuit board according to your requirements. As you customize the board, the cost changes regarding its characteristics. As you may want your printed circuit board, the costing will follow that.
Different manufacturers have different prices for their filter circuit boards as well. Manufacturers that are well trained and well experienced, tend to provide PCBs with better quality. So the price increases in that case.
The components affect the pricing as well. There are different components you can use on your filter circuit board. The different components have different prices so you may select the component according to your budget.
How To Choose The Right Manufacturer Of Filter PCB?
Choosing the right manufacturer for your filter printed circuit board is very necessary. As the whole output depends on how fine the manufacturer manufactures the PCB. Not choosing the right manufacturer can lead the whole project to go in vain.
You can follow some ways to choose the manufacturer that best fits your requirements for the filter board. Following them will help you to get the right one. You can consider the following ways while choosing the manufacturer for your printed circuit board project.
- They should have an expert group who will get the manufacturing done properly.
