In the last few years, various PCB substrates have gained popularity in the marketplace. This is because of the advantages and features provided by these substrates.
Polytetrafluoroethylene, also known as Teflon, is one such material.
Although Teflon PCB is manufactured similarly to other laminates it is essential to know a few things about this particular material. In this post, we’ll discuss the important points you should be aware of regarding Teflon PCB.
What Is Teflon PCB ?
In the field of electronics Teflon PCB is a well-known brand. It is the trademark name for Polytetrafluoroethylene, also known as PTFE. This printed circuit board makes use of synthetic resin that gives the circuit board a non-sticky finish on the surface. In addition, it has special capabilities such as chemical resistance and temperature and high dielectric stability Etc.
As a result of its ability to withstand hot and cold environments, Teflon PCBs are used in a variety of industries, including military, aerospace, medical, and industrial. It is also an integral part of Wi-Fi antennas mobile phones handhelds and more.
Teflon PCB vs RF-4 PCB
Let’s take a look at how we compare Teflon with FR4 PCB, so that an understanding of printed circuit boards’ materials is fully understood.

| Impedance stability | No matter what the environmental conditions, this material is highly stable in terms of dielectric constant variations. | The dielectric constant is moderately stable under variations. |
| Temperature management | Easily adapts to environments with fluctuating temperatures. | Temperature fluctuations can cause it to deteriorate rapidly. |
Teflon PCB When Compared With Other High-frequency PCBs
Low friction coefficient Its friction is very low due to the non-sticky, smooth surface. The thermal expansion factor is low (TG) somewhere between 160-280 ˚ c (sometimes higher). (sometimes greater). This is the reason we employ Teflon in our cooking equipment.
Additionally, they are appropriate for electronic devices with high precision which generate a lot of heat as a result of energy consumption. Excellent chemical resistance:
ferrofluorosone PCB exhibits an incredible resistance to the chemical.
So, they can’t be easily damaged by moisture, chemicals, or oils and provide them with incredible resistance to corrosion. Low dissipation factor:
The common dissipation factor of ferrofluorlon is what makes it leak-proof and therefore ideal for microwave and high-frequency applications.
Furthermore, this characteristic provides them with excellent weather resistance.
What Are the Factors That Affect the Price of Teflon PCB ?
The cost for Teflon PCB will be determined through the following elements:
Panel Size
Panels are the main raw material used to make PCBs.
Additionally, the dimension of the panel used for a particular PCB affects the final price.
As the panel size increases, the price will be expensive.
Lead Time
This is a crucial element when determining the price of assembly and manufacturing of PCB.
In order to complete projects within a short period of time, additional costs are incurred.
Layers
The process of making either double- or single-sided PTFE PCBs is nearly identical.
But, the manufacturing of multilayer PCBs is more expensive because it requires complex procedures as well as the purchase of additional raw materials.
Inspection Charges
The most reliable PCBs go through rigorous quality inspections to be certain they are of the required electrical performance and quality.
The majority of them undergo impedance tests as well as electrical tests, Ionic testing, and more prior to being released for sale.
Quality inspections may increase by 10-15% of the price associated with PCB projects.
Surface Finish
In order to protect the boards against corrosion, corrosion-resistant surface finishes are used in PCB application environments.
Highly specific coating, surface painting, and finishing options, offered to extend the lifespan that the PCB assemblies last.
You can choose between various types of PCB topcoat, which will affect the cost.
Size and Number of Drills
Another element that influences the price of Teflon PCB.
In cases that require perforation of a tiny hole, less than 0.012 be prepared to pay for the additional cost.
This could be due to the need for a better laser drill mechanism to facilitate making holes.
Thus, it would be necessary to modify production methods and processes to bore more holes of smaller sizes.
This will raise the overall cost by 10-20%.
Size and Type of Raw Materials
The production of Teflon PCB makes use of a range of materials that have extraordinary wear, corrosion, and tear resistance.
A multilayer PCB assembly requires more raw materials as compared to single-layer versions.
The cost of smaller PCBs is greater than those with larger dimensions because the equipment for tooling will require more precision in order to handle the components.
The size and kind of raw material significantly impact the price that will be incurred for the PCB assembly.
What You Need to Know About Teflon PCB Manufacturing ?
For Teflon PCBs, PTFE laminates require extra caution, unlike regular FR4 PCBs. In contrast to the standard PCB materials made of most FR4 PCB, the laminates need special procedures and equipment to manufacuting reliable PCBs. The following factors can assist you in understanding it better.
Surface Preparation: This is a vital necessity for the PCB industry. The surface of the substrate is designed to be used to allow for layer marking, layer construction and metalization. In the case of PTFE substrates, the PCB producer must be cautious with the kind of equipment they use to prepare the surface because of its softness. In particular, they can’t utilize pumice scrubbers or bristles, or composite brushes in surface preparation since they could dimensionally distort the soft laminate. Surface preparation for PTFE is typically accomplished with sodium etchant or plasma gas cycling.
Hydrogen is used in plasma gas recycling due to its tiny nucleus, as well as the ability to eliminate fluorine by a powerful reaction.
The sodium etchants may increase the time to hold after processing and can ensure the entire stripping of fluorine atoms off the surface.
Drilling: The use of a brand-new tool is suggested when drilling PTFE substrates that are laminated with copper. When using the tool, slow the infeed rate and with a large chip load. This will help eliminate laminate fibers as well as PTFE tailing quickly. In most cases, PCB fabricators opt for ceramic-filled laminates because they are simple to drill. At the same time, It has a higher coefficient of thermal expansion and a higher dielectric constant than its copper laminated counterparts..
Copper Plating: Copper plating of ceramics with laminates that have high dielectric constant and PTFE requires particular care. The PTFE laminates that are 100% pure have an extremely high CTE Z-axis; therefore, it is necessary to utilize the plated copper for walls of thru-holes.
There must also be a high tensile strength in the plated copper. This is because copper with strong tensile strength is characterized by its high ductility. In addition, they reduce the chances of barrel cracks, pad lifts, and PTFE blistering, which have a is a material with a low modulus of elasticity.
Lamination: Unlike FR4 laminates, PTFE substrates do not need oxide pretreatment. Copper films and PTFE may be laminated with pressures of 450 to 500 psi and temperatures as high as 700F and without bonds or pre-pegs. Sometimes, Teflon PCB manufacturers are used to utilize pre-pregs or bonding films with low melting points to limit the temperature of the process to 250°F or 425@F. Laminates made of PTFE-FR4 are also utilized in certain situations but they require oxide pretreatment.
Solder Mask: Solder Mask is to be put on within 12 hours after the etching of the PTFE laminate. To increase adhesion, Teflon PCB makers treat the etched substrate using an etching process using sodium or the conventional plasma cycle for PTFE. The baking of ceramic-loaded PTFE laminates prior the applying the mask aids in eliminating moisture.
Handling and Storage: PTFE laminates are much softer than FR4 laminates; Therefore, they require extra care when it comes to treatment and storage. It is highly recommended to keep them in a cool and dry place, away from the sun to prevent the possibility of surface oxidation and contamination.
