    PTFE PCB: The Ultimate FAQ guide

    PCBs are used to allow electrical functionalities of electrical components. You will find different PCB categories. PTFE PCBs are generally high-frequency and high-speed PCBs. Teflon is used to form the PTFE PCBs.

    Teflon is a high-grade PCB material. Generally, PTFE PCBs ensure the flawless signal passes with a constant dielectric constant.

    In regard to PTFE PCBs, we have found some basic questions. It is essential to understand the facts of PTFE PCB laminates when you are producing Teflon PCBs.

    In today’s FAQ guide, we will be discussing and answering several questions on PTFE PCBs. You may go through the entire post to get cleared about the PTFE Teflon PCBs.

    What Is PTFE PCB?

    PTFE, also known as polytetrafluoroethylene, is a synthetic substance that is very resistant to corrosion. Its high-grade qualities, which include hydrophobicity, non-wetting, high strength, and resilience to high temperatures, make it very advantageous for electrical applications.



    Its non-stickiness is perhaps its most well-known and noteworthy characteristic. Teflon is a brand that is based on PTFE. It is extensively utilized in the production of PTFE PCBs. It is made by polymerizing Teflon, which is a synthetic rubber.

    The PCBs that use PTFE as their base material are known as PTFE PCBs.

    Teflon is a material that has several advantageous qualities, including a low thermal coefficient of expansion, good chemical resistance, and low heat dissipation coefficients, among others.

    Additionally, it has a high level of cold resistance. High-frequency printed circuit boards (PCBs) take advantage of it because of these qualities. These characteristics help to guarantee that the PCBs function to their maximum potential.

    Furthermore, PTFE is well-known for its great resistance to oil, grease, chemicals, and moisture, which results in excellent lubrication. PTFE PCBs are ideal for this application since they are weather-resistant, very insulative, and need no glue.

    How To Make A PTFE PCB?

    Designing a PTFE PCB needs some essential steps. Generally, a PCB design starts with a schematic drawing.

    However, we have compiled gradual steps on making a PCB step by step. So, let’s explore the entire PCB manufacturing process.

    Schematic Drawing

    The schematic diagram is the most basic drawing for a PCB. It shows the shape and size of the PCBs. Schematic shows which components you are going to use, how you design the stack-up of the PCBs, how you connect the components.

    PTFE PCB Schematic Diagram Looks Like This

    PTFE PCB Schematic Diagram Looks Like This

    Also, the schematic determines the relationship among the component groups. In simple words, like your home design, the PTFE Teflon PCB schematic is the blueprint of your PCBs.

    Layout Design

    After drawing the schematic, you need to implement this as the PCB layout. The layout is the virtual design of the PCBs. For this, you have to import the schematic file of your PCB. You have to do this with a schematic capture tool in your PCB designing software.

    Designing PTFE PCB Stackup

    PCB stack-up organization is the next step of designing the PCB. For multilayers PCBs, you need to organize the different layers. The most common multilayer PCB starts with 4 layers and 6 layers. You can use the stack-up library to organize the layer stack up.

    Making PCB Board

    After designing the virtual parts, you need to make the PCB board with Teflon. Though you are making PTFE PCBs, the base material here is Teflon.

    Printing The PCB

    After the layout and the board is ready, now the time is to print the PCBs on the baseboard. You have different options to print a PCB on the boards. 3D printing, laser printing, etc., are among the available options.

    Placing Components

    After printing the PCBs on your PCB boards, now you need to place the components to function up the PCB. Be careful during placing the analog and digital components. Keep them separated from each other. You can use SMT or through-hole component placing technologies.


    After the placement of the components, your PCB components are ready for routing. Route your traces with proper routing lines.

    After routing the components, go through a PCB testing phase. The testing phase will ensure the functionalities of the PCBs.

    What Are The Properties Of PTFE Teflon PCBs?

    PTFE PCBs are great in some tolerances and resistance. Because Teflon has significant thermal, electrical, and mechanical characteristics. Because of the high-grade properties, high-frequency PCBs use Teflon.

    PTFE Is A High-Grade Material

    PTFE Is A High-Grade Material

    The following are some of the significant characteristics that PTFE holds.

    • They have great chemical resistance. When they come to different chemicals such as grease, oil, or other things, they do withstand their character.
    • Temperature resistance is one of the most significant characteristics of Teflon. Low or high temperature, it can withstand excessive temperature. Teflon can withstand even at -196° C.
    • The low dissipation factor makes the Teflon PCBs more insulating. For good insulating properties, PTFE Teflon PCBs are used in high-frequency PCB applications.
    • PTFE is a combination of carbon atoms and fluorine atoms. There is no stickiness and adhesive characteristics of Teflon.
    • It can operate in humid weather since it absorbs low water.
    • PTFE has a low dielectric constant and low-loss tangent make it high performing in high-frequency.

    What Are The Applications Of PTFE Teflon PCBs?

    What Are The Associated Materials Used In PTFE PCB?

    Along with PTFE Teflon, there are some other materials used in PTFE PCBs. They are as follows.


    Copper is the most important material for PCBs for its current conductivity. Generally, it is one of the main materials of PCBs. because conductive traces on PCBs are made of conductive copper. All current passes towards the components through the conductive copper layers of the PCBs.

    Copper Is A Highly Conductive Material

    Copper Is A Highly Conductive Material


    Solidadermask is a liquid protective substance that prevents oxidation of the external circuit of printed circuit boards. Soldermask also prevents liquid solders from escaping from the surface of printed circuit boards (PCBs).

    Glue Or Adhesive

    Glue or adhesive is used to attach the different layers of PTFE PCBs.


    Prepreg is a thin glass coating used with Teflon. It is the mechanical foundation that retains the Teflon in the appropriate spot. Prepreg begins as a liquid, and once dried, it becomes rigid.

    What Are The Differences Between PTFE Substrate And FR4?

    FR4 is one of the most popular PCB base materials. You will find most of the PCBs use FR4 as their base material. But, this is because most PCBs are for general uses. For example, low-layer count PCBs use FR4. It is also the cheapest PCB material.



    On the other hand, Teflon is an expensive material used in high-frequency PCBs. So, there are basic differences between FR4 and PTFE Teflon. From the following comparison table, you can differentiate both.

    StrengthGood thermal, electrical, and mechanical propertiesMore strength regarding mechanical, thermal, and electrical properties
    LayersUsed for lower layer-count PCBsUsed for higher-layer count PCBs
    ProcessingStandard procedures are Enough to work with FR4High-level skills, engineering, and machinery are required to work with Teflon
    ApplicationsStandard PCB applications in consumer, industrial, and othersHigh-speed, high-frequency applications in sophisticated applications such as aerospace, radar system, medical, industrial, etc.


    What Factors Should Be Considered During Manufacturing A PTFE PCB?

    Unlike FR4 PCBs, PTFE PCBs need special working skills, specialized equipment, and processing. So, you have to consider some facts during processing PCBs. They are as follows.

    Preparation for Surface

    When working with Teflon as a surface, you must exercise extreme caution and use specialized tools for surface preparation. You are not permitted to use harsh and difficult equipment such as abrasive filtration systems, composite brushes, or other similar items.


    You need to be of utmost care when drilling the Teflon substrate with copper. Do it easily and firmly. The firm drilling helps to eliminate PTFE leftovers.

    Copper plating

    The walls of through-holes must be plated copper to prevent corrosion. Copper with a high strength must be used to avoid the possibility of barrel fractures and pad lifts.

    Solder Mask

    You must apply the solder mask to the PTFE PCB boards within 24 hours after etching the boards. It is due to the improvement of the Teflon PCB plasma cycle production method.

    Solder Mask On PCB Holes

    Solder Mask On PCB Holes


    Because PTFE PCBs are softer than FR4 materials, you must exercise additional caution while handling and storing them. Maintain a cool and dry environment for them. Additionally, keep them away from direct sunlight to avoid oxidation.

    What Are The Types Of PTFE Teflon PCBs?

    You will find different types of PTFE PCBs. The following are some examples of Teflon PCBs.

    Single-Sided Teflon PCBs

    The most common type of Teflon PCBs is the single-sided one. A single conductive layer is used in a single-sided board. You will find all components on the other side of the PCBs. Most consumer and small electronics use single-sided PCBs.

    Double-Sided PCBs

    In the double-sided PCBs, there are two conductive laters are there. The insulating Teflon layer lays in the middle of the conductive layers. Conductive vias are used to link the two conductive layers.

    Double-Sided PTFE PCB

    Double-Sided PTFE PCB

    Multilayer PCBs

    Multilayer PCBs consist of at least three conductive layers. Besides this, a multilayer PCB can be formed with up to 100 or more layers. Multilayers stack up helps to minimize the size of the PCBs.

    High-Frequency PCB

    The PCBs with a high-frequency and small dielectric constant are known as high-frequency PCBs. High-frequency PCBs are used in high-power applications such as satellite, cellular phone base stations, and so on.

    These different types of PCBs are3 found in rigid, flexible, and rigid-flex forms.

    How To Test PTFE PCBs?

    Do you think about the consequences of the failure of an entire PCB lot? Like, you ordered a lot, and got faulty PCBs in the whole lot. Your total investment will go to disaster. To avoid this type of situation, you need to test the PCBs during the manufacturing phase.

    There are several testing methods available for PCB testing. Some popular testing methods are as follows.

    In-Circuit Testing (ICT)

    In-circuit testing is the most common type of PCB testing method. In this method, every single circuitry is powered by testing. ICT is also known as the bed of nails test. Fixed probes of testing check the solder connections of the circuitry that they all are okay.

    ICT is mainly performed after the manufacturing is completed.

    In-Circuit Testing

    In-Circuit Testing

    Automated Optical Inspection (AOI)

    In AOI, a single 2D camera or two 3D cameras take photos of the circuitries of the PTFE PCBs. Every photo then goes for a comparison with the schematic of the PCBs. If everything is matched with the schematic, the PCBs are okay. Otherwise, they are sent for fixing to the technicians.

    X-Ray Inspection

    In x-ray inspection, x-rays are able to test every single angle of the PCBs and find tiny faults. With x-ray testing, you can check the solder connections, internal traces, and barrels of the vias.

    Functional Testing

    Functional testing is exactly what it is named. You can test the functionalities as per the requirements. If the PCB functions correctly, the manufacturing is okay then.

    What Is Electromagnetic Interference In PTFE PCBs?

    Electromagnetic Interference refers to the disruption of electrical signals in PTFE PCBs. It happens because of radiation or induction. Electromagnetic interference may occur for different reasons.

    EMI Can Cause Different Signal Issues on PCBs

    EMI Can Cause Different Signal Issues on PCBs

    • Electronic circuits to occur EMI due to human-made reasons. On the other hand, you may see EMI occur due to lighting and cosmic noise.
    • Sometimes, the background noise of electronics causes EMI. In this case, EMI prevents the constant signal passing. Usually, switching systems cause these types of EMIs.
    • The communication system can face EMI from oscillators and transmitters.

    How To Prevent Electromagnetic Interference In PTFE PCBs?

    You can prevent EMI on your PTFE PCBs by following the following techniques. You can employ the techniques in three categories: Ground Plane, Trace Layout, and EMI Shielding.

    Ground Plane

    • Use more area for the ground plane. The signal can dissipate in a vast area, so the signal can avoid the crosstalk, noises, and emissions.
    • Ensure a solid ground plane for multilayer PCBs.
    • Make sure you connect each component correctly.
    • If you use a bypass or decoupling capacitors, connect them to the ground plane.

    Traces Layout

    • Keep analog and digital signals separated.
    • Keep signal traces short.
    • Ensure proper spaces among the traces.
    • Use vias correctly.

    Keep Digital And Analog Traces Separated

    Keep Digital And Analog Traces Separated

    EMI Shielding

    • Ensure physical shielding for components of the PTFE PCBs. You can use a Faraday Cage for doing this.
    • Make sure shielding for the cables that pass analog and digital current signals. Because they are a great source of creating EMIs.

    How Does 3D Printing Work For PTFE PCBs?

    3D printing is the method of creating a three-dimensional item via the use of a computer-based software procedure.

    PCB 3D Printing

    PCB 3D Printing

    When generating PCBs, you must ensure that the PCB boards are adequately supported by the 3D printing machine and that the digital file for the PCBs is appropriately established. Following your instructions, the 3D printing machine will produce the PCB in accordance with the design.

    Despite the fact that 3D PCB printing was only utilized for prototypes until the early twenty-first century, technology is currently being used commercially for mass manufacture.

    3D Printing Working Principle

    3D printing works based on two different methods: Using conductive filament, and creating hollow traces.

    Conductive Filament

    Using conductive filament is the most common type of 3D printing. The conductive filament is used to create a pattern of lines in the circuit board.

    Hollow Traces

    In hollow tracing, a 3D printer will create hollow traces on the PCB. Later on, the manufacturers will fill the hollow traces with conductive substances. See how 3D PCB printing works.


    What Is PTFE PCB Grounding?

    Consider your own home. You built a home but neglected to provide a sufficient foundation for it. It may come crashing down at any moment. Grounding is the basis of electrical equipment, and it protects them from being destroyed.

    The return channel of electricity for your PTFE PCBs that are linked to the earth is called grounding. Through the ground channel, any surplus or undesired power is securely returned to the earth.

    Ensure Proper Grounding For Your PTFE PCBs

    Ensure Proper Grounding For Your PTFE PCBs

    Grounding protects electronics from damage if there is a breakdown in the wiring system or if there is any unwanted electrical flow.

    The following are some of the most important reasons why you should ground your PCBs.

    • Grounding protects your PCBs from electrical overload.
    • Allows direct current to flow through the devices safely.
    • Ensure the stabilization of electric voltage.
    • Prevent damages of PCBs. Also, an uneven current flowing may cause fire which may cause physical injury. Grounding prevents all of them.

    What Is Impedance Matching In PTFE PCB?

    Impedance Matching

    Impedance matching, also known as controlled impedance matching, is the matching of printed circuit board substrates to enable continuous signal transmission across the conductive traces on the board. In order for the signal to pass, it must travel across a defined range.

    When it comes to high-frequency applications, impedance matching is critical in order to maintain continuous transmissions.

    The primary purpose of conductive traces on a printed circuit board is to transfer signals from one circuit to another. You must verify that the signals are in a certain condition in order to ensure that the needed signal propagation occurs.

    Consequently, in order to maintain signal integrity and clarity, you must provide regulated impedance. If this is not done, the components that the traces link to will act incorrectly. When this happens, signal mistakes ensue.

    What Is Surface Mount Technology In PTFE PCBs?

    Surface Mounting Technology (SMT) is a method of attaching components on printed circuit boards (PCBs). Components are put directly on the PCB surface in SMT. In the PCB sector, SMT has mostly supplanted the previous through-hole mounting method.

    It’s because SMT is both cost-effective and automated. Surface mounting components are the components that are employed in surface mounting technology (SMD). Because SMDs need fewer leads, they are smaller than through-hole components.

    Pick And Place Machine Placing SMDs On PCBs

    Pick And Place Machine Placing SMDs On PCBs

    Components are soldered onto solder pads that do not have any holes on a flat surface of a PCB in SMT. To begin, use a screen printing procedure to add solder paste to the solder pads.

    The PCBs are then put on a conveyor belt using pick and place equipment once they have been applied to all of them. SMDs are packaged in plastic tubes and must be soldered. The pick and place machine removes the packing tapes off SMDs before placing them on the PCB surface.

    In the following video, you may see how SMT technology works on a PCB.


    Why Should You Monitor PTFE PCB Temperature?

    You must monitor the temperature on your PTFE PCBs because high heat can alter the structure of your PCBs. Because of this, the PCBs lose their performance, even they can be destroyed.

    So, how high heat can harm your PCBs? Let’s check them.

    • Due to the high heat, PCBs generally lose their structural integrity. The layers are highly sensitive to heat, and different substances are used for conductive and insulating layers. So, the coefficient of thermal expansions is not the same for all materials. Because of this, uneven expansion happens for different materials.
    • Due to excessive heat, electrical circuits get damaged. Circuit lines change in an uneven way. Because of this, signal loss happens. Controlled impedance also fails to sustain.
    • Oxidation is the reaction of metals with the exposed environmental oxygen. It harms and destroys the components.

    How To Prevent Excessive Temperature In PTFE PCBs?

    As you know the consequences of excessive heat on PCBs, you must ensure that high heat does not rise in your PCBs. There are several ways you can prevent high heat on your PTFE PCBs. They are as follows.

    PCB Heatsink Absorbs The Excessive Heat Of PCBs

    PCB Heatsink Absorbs The Excessive Heat Of PCBs

    • The heatsink is the most efficient way of preventing high heat on PCBs. A properly placed and aligned heatsink can absorb most of the heat from your PCBs.
    • Cooling fans are another way of dissipating high heat from the PCBs.
    • Before producing PCBs, think about the materials and components you need to use on your PCBs. Make sure you are going to use high-grade materials and components.
    • Try to keep the PCB thickness at the highest point.
    • Applying lamination is a must for PCBs to prevent high heat.
    • Ensure proper spacing for the components.
    • Keep conductive traces short in length.

    How Can You Extend The Lifespan Of PTFE PCBs?

    Properly using and storing may significantly extend the lifespan of the PCBs. There are several steps to take to get the highest lifespan of PCBs. You can follow the following tips.

    • Keep clean the surrounding environment of the PCBs storing area. Do this regularly.
    • Regularly check your PCB components if they are in mint condition, or any damage happened.
    • Store the PCBs in a moisture-free storage house. You can use a Moisture Vapor Barrier to store them.
    • Keep the PCBs at a constant temperature level which maybe 60 to 70° F.
    • Keep your storage house away from dust, and extreme temperature.

    How To Choose The Best PTFE PCB Manufacturer?

    Choosing the right PCB manufacturer is a must when you want a successful production of your PTFE PCBs. So, how may you determine that a PCB manufacturer is fit for you? You should check the following criteria on them.

    • If they have proper certification.
    • If they facilitate a top-notch working environment and technology.
    • If they employed skilled staff.
    • If they are experienced in the PCB manufacturing industry.
