Classification of Rogers PCB Material
Rogers material belongs to high frequency and high-speed material. According to the dielectric constant, Rogers material can be divided into high dielectric constant material and low dielectric constant material, details as below. These are very important in Rogers PCB fabrication.
The Grade and Type of PCB Material
A, Tier 1: Normal-Tg FR-4 (like S1141) , Mid-Tg FR-4 (like TU-662 / R-1566WN), High-Tg FR-4 ( like S1000-2 / TU-752), Halogen-Free FR-4 (like TU-865).
B, Tier 2: FR-4 (like FR408HR, Megtron 4), PPO/PPE (like N4000-13 /EPSI, TU-872SLK/SP), Hydrocarbon (like NH9350).
C, Tier 3: Rogers ( like RO4350B PCB material), Panasonic ( like Megtron 6 PCB material), TUC ( like TU-883 PCB material), Taconic (like TLG-34/35).
D, Tier 4: RO4000 PCB material , RO3000 PCB material, RF-35, EZIO.
E, Tier 5: PTFE PCB material Note: The Df of the above materials are: Tier 1 > 0.010, Tier 2: 0.005–0.010, Tier 3: 0.003–0.005, Tier 4: ≤ 0.003.
A, Electronic/high-speed materials: Polyimide (PI), Polyphenylene oxide composites, Modified epoxy composites, Epoxy BT resin, Phenolic polyester fiberboard.
B, Microwave PCB materials: Liquid crystalline polymer (LCP), Hydrocarbon, Polytetrafluoroethylene polymer board (PTEF), PTEF glass-fibre fabric substrate, PTEF substrate.
C, Resin: PTEF (Dk@1MHz: 2.1; Df@1MHz: 0.0001) , PPE (Dk@1MHz: 2.5; Df@1MHz: 0.0007), Cyanate Ester (Dk@1MHz: 2.8; Df@1MHz: 0.005), Epoxy (Dk@1MHz: 3.9; Df@1MHz: 0.025).
D, Reinforced material: E-glass (Dk@1MHz: 6.6; Df@1MHz: 0.0012), D-glass (Dk@1MHz: 4.1; Df@1MHz: 0.0008), NE-glass (Dk@1MHz: 4.4; Df@1MHz: 0.0006), Aramid fiber (Dk@1MHz: 4.0; Df@1MHz: 0.02), PTFE fiber (Dk@1MHz: 2.1; Df@1MHz: 0.0001).
Note: Dk means Dielectric constant, and Df means: Dissipation factor. The Electrical performance difference of PCB material is mainly decided by the combination of resin system and Reinforcement material.
The Main Characteristic Parameter of PCB Materials:
The ratio of the capacitance obtained by filling the charging medium with the electrode with the specified shape to the capacitance when the same electrode is in a vacuum. The dielectric constant decides the electrical signal transmission speed in the medium. The lower Dielectric Constant, the faster the signal transmission speed, so when your products need fast signal transmission speed, you can refer to the Dielectric Constant of the material such as Rogers PCB materials which have very low Dk usually. The PCB material selection according to Dielectric Constant will be:
A, Dielectric Constant: 2.17–2.2 Select material types: PTFE Applied range: Microstrip, high frequency: 300MHz~40GHz.:
B, Dielectric Constant: 2.5–3.5 Select material types: PTFE + Ceramics Applied range: Microstrip, high frequency: 300MHz~40GHz.:
C, Dielectric Constant: 3.4–3.8 Select material types: PPO / Modified FR4 Applied range: Normal: 1MHz~10GHz.:
D, Dielectric Constant: 4.2–5.2 Select material types: FR4 Applied range: Normal: 1MHz~1GHz.:
E, Dielectric Constant: 10.2 Select material types: Ceramics Applied range: High voltage, high frequency: 800MHz~12GHz.
Dissipation factor generally can be defined as Insulating material or Dielectric in the alternating electric field, because the hysteresis effect of dielectric conductance and dielectric polarization, make a certain phase difference between the current phasor and the voltage phasor flowing in the dielectric, that will form a certain phase angle, the tangent value of this phase angle are Dissipation factor, and energy loss caused by that called dielectric loss, it is the physical quantity characterizing the power loss ability of dielectric and the signal loss ability of insulating materials. Such as Rogers PCB materials which have very low Df usually.
Nonpolar molecule material like PTFE, will not be affected by electromagnetic field change, the loss is relatively small. Normally the higher the frequency, the loss are bigger.
Expansion and contraction phenomenon of objects due to temperature changes. Unit is: ppm/℃
Grade of flame retardant characteristics can divide into 94V-0, 94V-1, 94V-2, and 94-HB. The most commonly used material is RF4 material normally which meets the 94V-0 standard.
TG is short for glass transition, it means the temperature of base substrate/laminates melting from solid state to fluid, namely melting point.
The normal TG value is over 130°. High TG is normally over 170°. Medium TG is approximately greater than 150°. The higher the TG value, the better the heat resistance of the material.
If the working environment temperature long term exceeds the TG value of the material, it will cause softening, deformation, melting, etc. and also there will be those problems if sharp decline in mechanical and electrical characteristics.
The maximum voltage value that the material surface withstands 50 drops of electrolyte without the formation of leakage traces. The unit is V. Normal FR-4 materials are around 175 V. But some materials can be 600V or more.
It refers to applying DC voltage to the printed circuit board and placing it in a high-temperature and wet environment, with the positive voltage between lines or holes. The electrochemistry of an electrical short circuit can be caused by the conductive substance growing along the glass fiber from the pole side to the cathode side by the products of the corrosion process.
Usually, it radiates from the anode in the circuit and migrates towards the cathode along the interface surface between glass fiber and epoxy resin, forming conductive filaments.
Via spacing of different networks: it is positively correlated with CAF results, that is, the larger the spacing, the better the caf performance
Through the accelerated aging test results of 6000 to 20000 hours, this index infers the maximum temperature that the material can withstand in 100000 hours, which is what we usually call the long-term use temperature of the plastic. RTI temperature also called UL temperature or electrical temperature is the long-term use temperature.
Normal FR4 VS Rogers PCB Material
1. The substrate of FR4 material is epoxy resin. The material is slightly hard; The substrate of Rogers material is hydrocarbon materials. Rogers is mainly used for high-frequency material. The material is a little soft. In the mixed pressure PCB, FR4 and Rogers are combined use.
2. Rogers materials are mainly high-frequency PCB materials. They are different from PTEF microwave PCB material. RO4000 series material does not need any special treatment for the through-hole process, and does not need to add any extra technology process; FR-4 epoxy glass cloth laminate, the main technical features are stable electrical insulation, good flatness, smooth surface, and not having pit. Thickness tolerance is standard. Very suitable to use in products with high-performance electronic insulation requirements, such as FPC stiffener, Backing boards for PCB drilling process, Glass fiber meson, Potentiometer carbon film printed fiberglass board, Precision planetary gear, Precision test plate, Insulating backing plate, Transformer insulation board, Motor insulator, Insulating board of electronic switch, etc.
3. The cost is also a very important factor. Customers are always looking for a manufacturer that can provide the best performance of the most economical PCB. People familiar with the PCB industry know that using FR4 material to manufacture PCB can save costs. FR4 material is suitable for products with low frequency and rated temperature settings. However, if your application is requiring high speed or operating at extreme temperatures, Rogers material should be used to produce PCBs, even if it is more expensive
4. The two materials require different impedance stability. There is no high-stability impedance without a high dielectric constant. Generally speaking, FR4 material has a maximum dielectric constant of 4.5. Compared to this, Rogers material with a dielectric constant value of 6.5-11 is preferred for high thermal applications. There is no high-stability impedance without a high dielectric constant.
5. The two materials have different abilities to handle the heat. For applications running at high speed, the thermal capacity of the PCB should be improved. Otherwise, the PCB becomes overheated and can cause quality problems in electronic products. This is also able to withstand high temperatures. Rogers PCBs rather than FR4 PCBs become the best choice for high frequency and high-speed applications.
6. The two materials have different signal loss dispersion coefficients. the dissipation factor of FR4 material PCB is 0.02%, while the dissipation factor of Rogers material PCB is 0.004%, therefore, compared with FR4 material PCB, Rogers material PCB can provide the most reliable results with minimal electronic signal loss.
7. The moisture absorption performance of these two materials is different. The moisture absorption performance of PCBs manufactured with Rogers material is better than FR4 PCBs.
8. There are also many differences between these two materials in terms of application areas as well as performance. On the one hand, FR4 PCBs are suitable for medium and low-frequency applications in normal environments. Rogers PCBs, on the other hand, are a favorite for space applications.
Should I choose FR4 or Rogers PCB Material?
Supplier customers may be confused should they choose FR4 material or Rogers PCB material for special projects. Here I want to take the example of radar PCB to talk about the manufacturing problems of FR4 material and Rogers material PCBs such as radar PCB will have more strict impedance control, which is a very important factor for radar equipment, and the matching impedance can produce cleaner signal transmission. Previously, the tolerance of signal bearing routing standard was ± 8-10%. This index for today’s high-frequency and high-speed circuits is not good enough. Today, the required tolerance is ± 6-8%. In some circumstances, the tolerance even reaches ± 5% or smaller.
This parameter change will help the manufacturing of these radar PCBs with particularly strict impedance control, and also will limit the number of manufacturers that can manufacture them since less than 5% tolerance is difficult to produce. But here in Viasion, we can supply high-frequency PCBs with less than 5% impedance tolerance.
Using Rogers’ super high-frequency PCB material makes the stack up, the tolerance of the dielectric constant is kept at ± 2%, and some products even can reach ± 1%. In comparison, the FR4 stack-up dielectric constant is up to 10%. Therefore, comparing these two materials, you also can find that Rogers’ material has a very low insertion loss may less than 0.001. And transmission loss and insertion loss of Rogers laminates are almost 50-80% lower than traditional FR4 material. So Rogers PCB products are normally used in microwave and RF applications.
Rogers 4000 series material has excellent dimensional stability of coefficient of thermal expansion (CTE) than normal FR4 material. Compared with normal FR4 material, when PCB experiences a cold environment, hot environment, and multiple reflow cycles, the thermal expansion and dimensions of the circuit board still can be maintained at a stable limit under higher frequency and higher temperature cycles, so when you need high dimensional stability on your products, you mean consider to use Rogers material.
In the case of mixed stack-up in PCB manufacturing, Rogers PCB materials can be easily mixed with high-performance FR4 using general manufacturing technology to produce. Therefore, it is not hard to achieve high manufacturing quality. At the same time, Rogers’ stack-up does not need a special through-hole preparation process.
Normal FR4 material always has a TG of 135 to 150 which can not meet the very reliable electrical performance, but high-performance FR4 materials have good reliability, such as high TG material with TG170 or above, such as SHENGYI S1170 and S1000-2 which we normally used. Even S1190 has a TG of 200.
