The efficiency of the dielectric material will improve with decreasing dielectric loss.

Nevertheless, it will begin to conduct current when the voltage or electrostatic field through the material is too high.

This phenomenon is referred to as dielectric breakdown.

What are the Features to Consider when Choosing Rogers PCB?

Here are the key features to consider when selecting Rogers PCB material:

Rogers printed circuit board

 Rogers printed circuit board

· Decomposition Temperature (T D)

Most PCB materials decompose when subjected to conditions beyond a specific temperature threshold, where the PCB loses around 5 percent of its general mass.

Therefore, it is important to use a Rogers PCB that can withstand your operating temperature, typically ranging from 200 ᵒC to 350 ᵒC.

In principle, the decomposition temperature needs to be above the operating temperature under which you will do the soldering.

· Co-efficient of Thermal Expansion

This is the rate of expansion of the PCB material when subjected to a temperature exceeding glass transition temperature (Tg).

It is an important factor to consider because there should not be a mismatch between the CTE of substrate and copper.

If the CTE of Rogers PCB substrate is greater than that of copper, the substrate expansion will be greater than copper.

This will result in the failure of solder joint or de-lamination.

Therefore, the recommended CTE for PCB is 70 ppm or lower.

· Dielectric Constant (Dk)

Also referred to as permittivity of PCB material, dielectric constant describes the quantity of charge the PCB material store.

The higher the Dk value, the higher will the capacitance is thus a higher the amount of stored charge. This leads to higher voltage appearance across the printed circuit board.

The dielectric constant of PCB depends on the frequency and normally reduce with increasing frequency.

PCB materials having higher dielectric constant gives smaller circuitry for a specific working frequency and vice versa.

For high-frequency applications, the Rogers PCB material must sustain a constant Dk over the operating scope of frequencies employed in that application.

· Moisture Absorption

In principle, the best Rogers PCB must be a type with nearly absorbs no moisture when immersed in a liquid.

Most materials have an absorption value ranging from 0.01 percent to 0.20 percent.

The higher the percentage of absorption, the greater will be the effect on the electrical and thermal characteristics of the PCB material.

What is the Differences Between Rogers PCB and other PCB Materials?

The main difference between Rogers PCB and traditional PCBs originate is their application.

Rogers PCBs are commonly employed in high frequencies applications, whereas you cannot use traditional PCBs for uses involving high frequencies.

Furthermore, Rogers PCBs boasts of the lowest water absorption in comparison to any other type of printed circuit board.

You can as well use Rogers PCBs in an unstable environment and harsh conditions, such as defense and aerospace.

On the other hand, ordinary PCBs are not suitable for low exhaust conditions like in standard switchboards.

Finally, the two PCBs also differ in terms of cost. Rogers PCB is more costly thanks to its high quality.

What is Pre-preg in Rogers PCB?

Pre-preg is a short form for pre-impregnated composite fibers, which helps in influencing the performance traits of the PCB.

Moreover, it is also a term used in the PCB manufacturing sector to define the bonding ply materials utilized to bond a multilayer Rogers printed circuit board together.

Which are the Methods of Testing Dissipation Factor and Dielectric constant of Rogers PCB?

There are a number of techniques for measuring dissipation factor and dielectric constant of Rogers PCB including:

  • Stripline Resonator Method
  • Long Stripline (LSL) method
  • Full Sheet Resonance (FSR) method
  • Cavity Resonator method

Stripline Resonator Method is the commonly applied technique for quality control testing of PCB laminates.

It is regarded as the standard test technique for majority of high-frequency Rogers PCBs.

This is because of its potential to conduct fast measurements using a similar test set-up.

The stripline circuit comprises of a resonator pattern card in the middle of two laminate samples engraved to eliminate cladding.

This method offers the advantages of being operator-independent, unsophisticated procedure, and swift measurements.

What is RO3000 Series Laminates in Rogers PCB?

RO3000 Series Laminates

RO3000 series laminates

RO3000 Series laminates are printed circu9t board materials with uniform mechanical features, irrespective of the chosen dielectric constant.

This enables the development of multilayer Rogers PCB designs that utilize different dielectric materials for independent layers, without experiencing reliability or war-page issues.

In addition, the dielectric constant of the RO3000 series is uniform over a broad range of temperatures.

Some of the advantages of RO3000 Series laminates include:

  • Come in a wide scope of dielectric constant (3.0 to 10.2)
  • Low Z-axis offers plated through-hole dependability
  • Available in varieties having and lacking woven glass reinforcements
  • Least loss commercial laminates

Why is it Important to Consider Temperature change when Designing Rogers PCB?

Changes in temperature can significantly influence the dielectric constant characteristic based on the dielectric material utilized in the laminate.

Alterations in the dielectric constant can impact on signal integrity and result in unstable operation within the design of the Rogers PCB.

Which are the Factors that Affect the Dielectric Strength of Rogers PCB?

Dielectric strength is defined as the voltage gradient that can be ensured by an insulating material before the occurrence of dielectric breakdown.

Dielectric breakdown is the stage at which there is sudden excitement of large quantities of electrons to energies in the conduction band.

That is, the point at which the insulating material fails to withstand current flow.

There is permanent degradation of the insulation after the occurrence of the breakdown.

The dielectric strength value stands for the size of an electric field needed to cause the dielectric breakdown.

Therefore, it is important to make sure that the potential exerted never exceeds the dielectric strength when designing a Rogers PCB.

When it surpasses, the dielectric materials turn conductive and there may be localized heating.

With the above in mind, here are the three key factors that influence the dielectric strength of Rogers PCB:

  • The thickness of the board;
  • Frequency and
  • Environment (especially absorbed moisture).

What is Impedance in Rogers PCB Materials?

Impedance is the measurement of the opposition or obstruction of an electric current to energy flow when you apply some voltage.

An ideal example of impedance is a resistance line on an electric current.

Balanced impedance is critical in most designs of PCB, and this is an aspect where Rogers PCB materials and FR-4 PCB materials differ.

In terms of impedance stability, PCB materials by Rogers feature a wide scope of dielectric constant in comparison to FR-4 types.

Though the cost of FR-4 materials is lower, they experience extensive dielectric constant and temperature variations.

The variation occurs across the length and breadth of the PCB substrate.

High-frequency PCB laminates are a perfect option in case a circuit ought to function with minimal variations across wide temperature changes.

In this case, Rogers PCB is the better choice, specifically when most of your applications entail operating in high-temperature conditions.

What is the Recommended Flammability Rating of Rogers PCB?

High frequency Rogers PCB

High-frequency Rogers PCB

Some of the uses of Rogers PCB designs need a self-extinguishing material because of the environment.

UL 94V-0 rating is among the categories of self-extinguishing substrate.

PCB materials with this flammability rating have the capacity to self-extinguish in 10 seconds and do not drip flame or resin while burning.

However, materials with burn time exceeding 10 seconds may obtain ratings like V-1 and V-2 depending on their burn duration.

What are the Benefits of using Rogers RO4000 PCB Materials?

Rogers RO4000 pre-pregs and hydrocarbon ceramic laminates are the leading in PCB industry.

They are commonly applied in millimeter-wave and microwave frequencies.

This low loss type of Rogers PCB material provides easier use in printed circuit board manufacturing and streamlined features over conventional PTFE materials.

The main benefits of rogers RO4000 series materials include:

  • Feasible with FR-4 PCB fabrication processes
  • Well regulated dielectric constants (Dk)
  • Thermally versatile – lead-free soldering compatibility
  • Above-average thermal conductivity (.6-.8)
  • Low Z-axis CTE for dependable plated through-hole quality
  • Available in broad dielectric constant range (2.55-6.15)
  • Optimized cost and microwave/radio frequencies performance
  • UL 94 V-0 flame-resistant varieties available

How does the Cost of Rogers PCB compare to FR-4 PCB?

When it gets to the fabrication of printed circuit boards, the kind of PCB material utilized and cost matter significantly. There is big difference in terms of the cost of Rogers PCB and FR-4 PCB.

The price of Roger materials is higher than that of FR-4 materials.

FR-4 is among the low-cost materials applied in the fabrication of printed circuit boards.

They are preferred due to their reduced costs of processing.

Nonetheless, FR-4 PCB are recognized for their low performance.

Therefore, FR-4 PCB is the better option if cost of materials and processing requirements is of great concern to you.

Nevertheless, if you require a high-performing printed circuit board and cost of materials is not an issue, then Rogers PCB the best option.

Even though the cost of Rogers materials may be relatively high, the resultant PCBs are high-performance products suitable for a variety of applications.

Moreover, selecting Rogers PCB is the right choice due to the reality that cheap is always expensive in the long run.

How is Dispersion Important in Rogers PCB?

Dispersion is a characteristic of printed circuit board materials that is closely linked to dielectric constant.

All PCB materials display certain degree of dispersion, which represents the change in dielectric constant as a frequency function.

Rogers PCB with minimal dielectric constant changes with frequency will display minimal dispersion, which a good feature of high-speed digital PCBs.

Several characteristics of PCB materials can cause dispersion, including the dielectric material polarity and loss of the material.

Moreover, roughness of the copper conductor surface equally influences the loss of the PCB material at higher frequencies.

When Rogers PCB material displays varying Dk values for varying harmonic signal constituents making a high-frequency digital signal, it will result in losses.

This can as well lead to frequency shifts for those harmonics, causing high-speed digital signal degradation.

How do you Ensure Impedance Matching in Rogers PCB?

Impedance matching of microwave or radiofrequency Rogers PCBs can be a challenging task.

It can be difficult without managing unexpected changes in material parameters, like inconsistent dielectric thickness and copper cladding.

The main parameters of PCB laminates are strictly regulated to help to ensure that impedance matching is easier.

The control also ensures that the process is based on the anticipated impedances of PCB dimensions for a distinct efficient dielectric constant.

In general, the properties of Rogers PCB material that are crucial to impedance matching and sustaining a desired impedance comprise of:

  • Tight regulation of dielectric constant;
  • Regulation of conductor thickness, and
  • Regulation of dielectric thickness.

For instance, to achieve impedance matched Rogers PCB, the dielectric material should maintain ±10% or better thickness tolerance.

This helps to attain impedance matches that are constant and predictable.
