PCB Material Categories

Normal Speeds and Normal Loss

They are the most commonly used PCB material–in the family of FR-4. The dielectric constant (Dk) against frequency response isn’t exactly smooth and they have more dielectric loss. They can be used for up to2GHz or more applications. One example can be found in Isola 370HR.

Medium Speed and Medium Loss

Materials that are medium-speed have the appearance of a flat Dk against frequency response curve and have an average dielectric loss of half of the regular speed material. They are ideal for up to 2GHz applications. Nelco N7000-2 HT is an example of this material.

Low Loss and High Speed

The materials have lower Dk and frequency response curves and have a very low loss of dielectric. They also produce less electrical noise when compared with other materials.

They are suitable for applications up to 20GHz. One example of this material is Isola I-Speed.

What Is PCB Laminates ?

Knowing the various kinds of laminates for printing circuit boards is essential for the development and design procedure your PCB maker will be through. The kind of laminate you pick will affect the quality and stability of your PCB.

The PCB’s laminate is the glue that holds the layers together. Typically it has four layers on this board: Substrate, Soldermask, Copper, and Silkscreen (from the bottom to the top). The laminates are developed by curing under pressure and temperature of cloth by using thermoset resins to form the final piece of uniform thickness.

If you notice a kind of laminate that is written out, it’s likely to appear like this The letters are”FR-4″ (with the FR-4 being the most commonly used material). These letters and numbers represent the features of the laminate that is produced. The most important attributes include the dielectric constant (DCE), loss factors shear strength, tensile strength and glass transition temperature and the extent to which thickness changes as the temperature (the Z-axis’s coefficient of expansion).

Types of PCB Laminate

PCB Laminates Materials

The following list consists of different kinds of PCB laminates as well as the PCB materials that are required, starting with the most commonly used types. The name of a laminate is derived from the resin that is used.


What can make FR-4 the most popular laminate is the way it performs across all aspects. It has a high strength-to-weight ratio and is also flame-resistant, which increases its durability, and when there is an increase in temperature its electrical, mechanical, and physical properties remain the same.

High-Performance FR-4

It is recommended to use a high-performance laminate called FR-4 when working with multiple-layered PCBs. It offers high reliability due to its higher Tg and is more suitable for circuits that operate at high frequencies due to its dielectric properties that are low.

High Tg Epoxy

For PCBs with multiple layers, the High Tg Epoxy will be the most appropriate. Tg is the term used to describe temperature. Similar to the melting point, the Tg is the vitrification temperature. The higher the number, the more rigid it will become. A material that has the highest TG (over 170o C) offers better temperature, moisture, and chemical resistance in addition to greater stability.

BT Epoxy

The best choice for lead-free PCBs This BT Epoxy Laminate is renowned for its exceptional mechanical, thermal and electrical qualities. Multilayer PCBs commonly use this laminate. It can also keep the bond strength even at extreme high temperatures.

Polyimide (PI), Dupont

This type of laminate has extreme stability in the environment. The Polyimide laminate works with rigid-flex, high-density circuit boards as well as multilayer PCBs. It also provides extremely high levels of the chemical, thermal and mechanical qualities. A polyimide laminate is perfect for applications that require advanced technology, such as automotive, aerospace, military as well as consumer electronics.

Copper Clad (CCL)

Copper Clad Laminated is comprised of glass fibers or wood pulp paper to reinforce the material. It is typical to use CCL laminate to build high-voltage circuits that are based on certain aspects like appearance, size, electrical, and physical chemicals in addition to environmental quality.

Teflon, Rogers And Many More Special PCB Laminate

The most widely utilized material for high-frequency applications. Teflon materials are available in a variety of varieties. The easiest materials to utilize for manufacturing are Teflon with woven glass. There are a variety of challenges to making Teflon PCBs which can create issues when working in a traditional shop for boards.

How to Choose PCB Laminates

FR4 PCB Copper Clad Laminates Materiales

When we discuss the PCBs in products, the discussion is bound to lead to a question–What PCB laminate materials do you employ? PCB laminate is a type of material that resembles a plate made by dipping electronic fiberglass or other reinforcing materials using resin and then coating with copper foil either on both sides and then hot laminating. The efficiency, cost, and durability of printed circuit boards are based on the type of PCB laminate chosen in large part.

So What Is Considered When Deciding on PCB Laminated ?

● The Glass Transition Temperature (Tg) is the temperature at which higher molecular weight substances change from their glassy state to the state of rubber and viscous. This is when the hard PCB laminate ceases to act at this temperature and begins to behave softer.

Tg isn’t the measurement of the working temperature that is the highest but rather the critical value. It is a crucial performance indicator for PCB laminates (Z-axis expansion is a crucial indicator to define the effect of Tg’s effect on the PCB laminate, and is an indicator of the reliability of plated through holes) for example, FR-4 materials are typically identified by various Tg values. The more Tg is higher is, the better the quality of the material.

The most common materials FR4 have Tgs at 130°C. (In PS Electronics the temperature can be 140°C ). One type of PCB laminate with a higher Tg of 250 or higher includes polyimides (PI).

Dupont Flexible Polyimides Raw Materials

● Thermal Decomposition Temperature (Td),This property varies greatly with the composition of materials, from a low of 300°C for many epoxy systems to over 400°C for some flexible PCB laminates.

● Dielectric Constant (Dk) and Loss Tangent (tanδ),the dielectric constant determines the speed at which an electrical signal will propagate. Higher dielectric constants will result in slower signal propagation. greater dielectric constants cause slower propagation speeds. Loss Tangent is an indicator of how much strength of a signal gets lost when it travels through a transmission line of the dielectric material.

To achieve high-speed transmission, high-frequency high-speed PCB boards need to employ laminates that have low Dk and tanδ, for instance, PTFE with very low Dk and tanδ. It is among the top applications that require high frequency.

● As a result of a change in temperature, matter changes its shape, area, and volume, which we call Thermal expansion. It’s a result of the durability of the material’s dimensions and influences the quality of soldering.

The majority of the time, FR-4 has a relatively good CTE (Coefficient of Thermal Expansion) between 14 and 17 ppm/C. However, it can increase dramatically when temperatures exceed its Tg value.

● The thermal conductivity (TC) of a material is its ability to conduct heat. It is often discussed in opposition to high-power devices like lighting equipment, and in that case, it is the most significant performance.

The PCB made of metal laminates, such as aluminum and copper have high thermal conductivity (m/wk).

● The “green” requirement is driven by market considerations and policies. RoHS compliance has become a consensus among electronics manufacturers across different countries and will be a future trend that should be considered when selecting PCB laminates.

A good example of this is one that is a non-halogen application meaning that PCB laminates don’t contain elements that are halogen, like bromine, chlorine, and so on. These elements are harmful to humans and to the environment. There is no definitive obligation that exists if you have relevant cases in your marketplace Please, make sure to prioritize this issue.

About Printed Circuit Boards Materials Classification

PCB Materials

Presently, the most widely used dual-sided substance is called FR-4 as well as CEM-3 substrate. Both are fire-repellants (UV 94-V0). The FR4 material is a copper-clad material comprised of electronic grade, alkali-free glass fiber cloth embedded with brominated epoxy resin that is flame-retardant and copper foil on either or both sides along with hot-pressing.

The CEM-3 type of material is an electronic grade, alkali-free glass non-aromatic cloth that has brominated epoxy resin that is flame-retardant inside the middle layer. The insulation layer. One sheet has a flame-retardant brominated epoxy on both sides of the fabric. Copper foil is located on either or both sides of Resin electronic-grade, alkali-free glass fiber cloth, and then is formed by pressing hot to form the laminate with copper cladding.

PCB Material Types

● FR-1:phenolic substrate for paper Breakdown voltage 787V/mm Surface resistance and volume resistance less than the FR2.
● FR-2:phenolic substrate for paper Breakdown voltage 1300V/mm
● FR-3:The epoxy paper substrate is FR-3.
● FR-4: Epoxy glass fiberboard
● CEM-1: epoxy glass cloth-paper composite board
● CEM-3 Glass Matboard
● HDI boards HDI board: High-density Interconnect

Copper-clad Laminate is also known as substrate. The reinforcing material is soaked in resin, and one or both of the sides is covered in copper foil, and the board material is made by pressing hot, which is known as copper-clad laminate. It is the fundamental component that makes up PCB which is often referred to as the substrate. When it is utilized to make multilayer PCB board manufacturing it is known as “core.”

The Most Common Copper-clad Laminates Include

● The phenolic cotton paper is FR-1 The kind of substrate is sometimes known as bakelite (more affordable than FR-2)
● FR-2 Phenolic cotton paper
● FR-3: Cotton paper epoxy resin
● FR-4: Glass fiber cloth and epoxy resin
● FR-5: glass fiber fabric and epoxy resin
● FR-6: matte glass, polyester
● G-10 Glass fiber cloth epoxy resin
● CEM-1: cotton paper, epoxy resin (flame retardant)
● CEM-3: cotton paper, epoxy resin (non-flame retardant)
● CEM-4: glass cloth epoxy resin
● CEM-5: glass cloth polyester
● AIN: aluminum nitride
● SIC: silicon carbide

Presently, the copper-clad laminates that are available on the market are classified as follows by base material:

● Paper substrate
● The glass fiber fabric substrate
● Fiber cloth made of synthetic fiber
● Non-woven substrate
● Composite substrate
● Other

Copper-clad laminate is a term used to describe substrates like paper and fiberglass cloth that are coated with resin to form bond sheets (adhesive tape and paper). After the bonding sheets are combined each side is covered by copper foil. The foil is then dried by heating and pressure to form the product into a plate.

Shielding board material is copper-clad laminate, which has an outer shielding layer or a patterned circuit within the layer that is inside. If the circuits on both sides are processed, they will become the multilayer board. This is also referred to as”a “copper clad laminate with a shielding layer.”

Multilayer materials are laminates with copper-clad and adhesive sheets (adhesive cloth) employed to construct Multilayer Circuit Boards. In recent times, these have been expanded to include copper foil that is grease-coated (RCC) and used for the production of multi-layer laminates. The term “multi-layer board” refers to a board for circuits having two layers of circuits that are patterned on both sides as well as the inside.

Special substrates are the laminates and steel cores, as well as other types of special substrates. utilized in the additive process that isn’t part of the types mentioned above of plates that are special.

Metal core substrates also comprise resin-coated substrates (FBC etc.) Other examples are:

● Aluminium core substrates for base.
● Copper core base substrate.
● Base substrate for ceramic core.
● The glass base material.

Basic Knowledge of PCB Materials

Copper-clad Laminate Is Also Called PCB Substrate

● A plate-shaped substance created from filling reinforcing materials (glass fiber cloth often referred to as glass fiber) using resin (PP sheet) that is covered on the entire surface with copper foil and hot pressing, referred to as a pressure plate with a copper-clad layer (Copper Clad Laminates [CCL(also known as copper-clad laminates, [CCL]).

● The primary PCB material is commonly referred to as the board.

● When it is employed in the manufacturing of multiple-layer boards it’s often referred to as”core board” (or the core).

Copper Foil

PCB Copper Foil Printed Circuit Board

Copper foil thickness is expressed in pounds (ounces) which is a unit of mass. is the standard unit for mass. The thickness of the copper foil is described in terms of “thickness” by mass. In general, copper foil thickness is measured in ounces, 1oz copper foil. One ounce of copper should be spread evenly over one square foot. The size of copper foils is known as 1oz copper thickness. its thickness is precisely 1.37mil (about 1.4mil).

The copper foil has a standard thickness of 12μm (1/3oz), 18μm (Hoz), 35μm (1oz), and 70μm (2oz).

Prepreg Principle As a Process (Prepreg or PP)

It is a sheet material that is made using treated fibers of glass filled with glue followed by heat treatment (pre-baking) to let the resin go through in stage B. The basic principle of this pressure plate is that it uses the leftovers from the B-stage to convert the C-stage process to connect the different circuit layers together into one.

Performance Indicators Common to All Substrates for Substrates

DK: It is the dielectric constant of the material. Only through reducing DK can a signal with a fast propagation speed be realized.

Df: Material’s dielectric loss angle. the smaller this angle the smaller the signal propagation loss.

Be aware that DK is mostly connected to the impedance of the signal network. It is also connected to the capacitance of the plates. Df is mostly connected to the depletion of signal networks. Among the factors affecting DK are:

● Resin (DK of epoxy resin is 3~4);
● Fiberglass cloth (DK between 6 ~7);
● Resin content (RC value).

Tg glass transition temperature has the most influence on the vias. Glass transition temperatures are the primary characteristic of the polymer. It is the term used to describe the transition of the resin that changes from hard (glassy) and the soft (rubbery). this is the temperature at which the shape changes.

Presently, the Tg of the FR-4 board is usually 130-140. However, when it comes to the production of the printed board, you will encounter a variety of issues that go beyond the range and could have a significant influence on the process effect and final quality of the finished product. So the increase in Tg is the primary way to increase the heat resistance of the FR-4. Its Tg definition is like this.

● Normal Tg sheets: 130-140℃.
● Medium Tg sheet: 140~150℃.
High Tg board: higher than 170degC (PCB boards that have greater than 8 layers are required to be used with High Tg board).
