Epoxy Resin PCB – The Ultimate FAQ Guide

Are you wondering about getting the best insulators for circuit boards to cope with the aggressive environment?

Or do you demand a PCB that can protect your circuit board against moisture or vibration?

Don’t worry! Epoxy resin PCB can be your best choice in this case.

Here, the following guide will extensively be taught you about Epoxy Resin PCB.

Let’s get deep into this:

What is Epoxy Resin PCB?

The printed board circuits which are laminated by epoxy resin are called Epoxy Resins PCB.

These are highly insulated circuit boards protected against harsh and aggressive environments by the epoxy resin material.

Since the material is an insulator, you can ensure the circuit is completely protected from any mechanical and thermal shocks.

If we talk about the Epoxy Resin printed circuit board, they are made up of non-conductive substrate material, and the copper layers are buried beneath or externally.

There may be one or two layers in the normal PCBs, but if you want to apply high density, you should have a PCB with sixty or more layers.

Unlike all other types of PCBs epoxy resin PCB is a polymer that is highly viscous, synthetic, and a mixture of organic compounds and commonly used as adhesives.

However, due to the perfect mechanical and thermal resistance properties, they are mostly used to make insulated printed board circuits.

What are the Properties of Epoxy Resin PCB?

Epoxy Resin PCB are the longest lasting printed boards of this decade and have lots of stunning properties, which includes:

• High Strength: They are strong and can bear more weight as compared to the other boards.
• Low Shrinkage: Epoxy Resins have flexible nature. That’s why their printed boards have low shrinkage risks.
• Excellent Adhesion to Substrate: The material used in these boards has sticky nature due to which Epoxy Resin boards have excellent adhesion between their substrate.
• Insulation: These printed boards are insulated and resist electrical shocks due to the resistive properties of Epoxy Resin.
• Thermal Resistance: Epoxy Resin PCB provides resistance against thermal and electrical conductivity to avoid any shock at the end.
• Cost-Effective: These printed boards are cost you a bit high due to their more effective properties and long-term valuation.

Properties of Epoxy Resin PCB

What is the Substrate Material of Epoxy Resin PCB?

FR-4(modified epoxy resin) is the substrate material of Epoxy Resin PCB, which is responsible for the structure and overall shape of the board.

FR-4 is the fiberglass-epoxy laminate material that is flame-retardant and provides electrical insulation between the conductive parts.

This substrate is famous for its excellent strength to weight ratios and high-pressure resistance.

While it has been approved that FR-4 has water absorption near to zero, that’s why it has higher mechanical strengths with unique insulation qualities.

Additionally, whenever FR-4 is used in making Epoxy Resin PCB, a thin layer of copper foil is necessary to be laminated on both sides of the panel.

Substrate Material of Epoxy Resin PCB

Do the Materials in Epoxy Resin PCB Impact Its Structure and Performance?

Yes, the materials in Epoxy Resin PCB highly impact its overall structure and performance.

These printed boards are material sensitive, and their structure is completely dependent upon the nature of substrate and material.

A printed board requires a point to which it holds all of its other components. Here, the substrate performs this job, and that’s how the overall structure is dependent upon the substrate.

The performance of the printed board will be increased or decreased based on the nature of the substrate.

For example, if the substrate is flexible, then you’ll have more design options, but if the substrate is rigid, you couldn’t design much although, it may add durability and strength to the Epoxy Resin PCB.

Moreover, choosing the right materials is the first step towards building a high-quality Epoxy Resin PCB because it truly decides the overall performance of the board.

Materials in Epoxy Resin PCB

What is the Impact of Sunlight on the Epoxy Resin PCB Substrate?

Sunlight badly impacts Epoxy Resin PCB Substrate because FR-4 is not defensive against harmful ultraviolet radiations of the sun.

Consistent UV radiations have been observed to deteriorate fiberglass, thus leading to weakening and fading (discoloration).

Although fiberglass is one of the most durable materials in Epoxy Resin and unlike wood, it won’t decay from exposure to moisture, UV radiations can bloom this material.

FR-4 itself can bear higher Celsius temperatures other materials of the printed board are unable to bear heat shocks, or you can say these materials do not even operate safely up to 120 Celsius.

This is the only disadvantage of Epoxy Resin PCBs is recorded till now. Most of the leaded solder paste of PCBs is melted at around 160 degrees Celsius.

Impact of Sunlight on the Epoxy Resin PCB Substrate

Why is Epoxy Resin PCB Uses in Circuit Boards?

Epoxy Resin PCBs are used in circuit boards to connect the electronic components electrically.

These components are joined through conductive pathways where the current passing copper sheets are laminated with the non-conductive substrate.

In addition to the Aluminum PCB, breadboard circuits are also used instead of PCB/ Epoxy Resin PCB.

Still, due to their limited current carrying capacity, experts start using Epoxy Resin PCB Substrate, which gives them appreciating results.

Another reason behind the use of Epoxy Resin PCB in the circuit boards is that it has wide traces along with the terminals, so more current can run through the wider traces, or external connections can be developed through the terminals.

Furthermore, some other reasons why Epoxy Resin PCB is used in circuit boards are given below:

• Costs you low (in terms of overall circuit board expenses)
• Epoxy Resin PCB is re-workable and widely used
• They produce low electronic noise in circuit boards with an excellent shelf life
• They save extra wire with their compact size
• The Epoxy Resin PCB takes less time in assembling a circuit as compared to the conventional methods
• Short circuit proved
• If you use Epoxy Resin PCB in your circuit, it would be very easy for you to replace particularly failed components
• Brings reliability to the performance of the circuit

What Appliances Contain Epoxy Resin PCB?

Appliances contain Epoxy Resin PCB and heavy copper PCB, so they become efficient and avoid bulky wiring. The main purpose of the manufacturers is to fix all of the electronic components in a compact space, and that’s what Epoxy Resin PCB provides them.

The manufacturers of PCBs need to give a warranty of their product to the customers so that they won’t compromise on the authenticity of the electrical components used inside the product.

Epoxy Resin PCB gives mechanical support to their components and helps to avoid any electrical shock.

The most prominent reason behind using Epoxy Resin PCB in appliances is that the substrate used in these PCBs provides insulation and resistance against mechanical, chemical, and thermal conductivities, which directly means that your appliances can avoid short circuits. That’s what provides reliability to customers.

Appliances of Epoxy Resin PCB

Is Epoxy Resin PCB Cost-Effective?

Yes, Epoxy Resin PCB is cost-effective, but the larger a PCB is, the more it will cost you.

Generally, the normal sizes of Epoxy Resin PCBs are 18″ × 24″, 18″ × 12″, 9″ × 24″, and 9″ × 12″, which costs you low. But, above that, it’ll cost you high.

If you want to design a big-sized PCB, you need to have more material as compared to the normal one. That’s what makes PCBs costly.

Here, if you were doing duplication of the whole circuit designing process and placed the components on either of the sides of the circuit, it will cost you high.

The reason behind this is, the PCB assembly is costly due to the leadless components and fine pitch.

This would require a unique assembly process and special inspection techniques.

Cost-Effective Epoxy Resin PCB

Does the Epoxy Resin PCB Insulate the Boards?

Yes, Epoxy Resin PCB insulates the boards because Epoxy Resin is itself insulators, so they help the whole of the circuit board to become an insulating board.

As compared to the Rogers PCB, Epoxy Resin is famous for its excellent adhesion, good strength, and moisture resistance.

And that’s why these are widely used in industries to provide mechanical support to their electrical components.

The experts have suggested that instead of using a rubber sheet, you can use these insulation materials to avoid electrical resistance and to make your board insulator.

Furthermore, the Epoxy Resin PCB is also appreciated and used to insulate the boards due to the low shrinkage property along with the strong adhesion.

Epoxy Resin PCB Insulate the Boards

What are the Properties of Epoxy Resin in PCBs?

Epoxy Resin efficiently protects the PCB’s electrical components against moisture, dust, and short circuits.

They provide resistance against mechanical, chemical, and thermal conductivities, so the performance of the circuit board cannot be affected.

According to the mechanical experts, the main reason to use Epoxy Resin PCBs is that they are compatible with fiberglass (FR-4), which is the leading substrate of Epoxy Resin PCB.

The Epoxy Resin is the low cost that a person can easily afford and to make a circuit board for his use.

While the manufactured printed circuit boards are quite costly. The printed circuit boards need to be insulated, and that’s what epoxy resin does.

These will provide strength to all of the electrical components of a circuit board, so any inconveniences should be easily avoided.

Properties of Epoxy Resin in PCB

Is Polyurethane Present in Epoxy Resin PCB?

Polyurethane is a plastic-type material and can exist in various types. Epoxy Resin PCB is often a type of polyurethane and belongs to a polymer class containing epoxy functional groups.

It couldn’t be wrong if we say polyurethane is present in Epoxy Resin PCB.

It surely provides elasticity and flexibility, while Epoxy Resin PCB provides strength to the various electric components.

The polyurethane is elastic because its floor coating is highly flexible and elastic, while the floor coatings of Epoxy are harder and brittle.

Epoxy Resins contains four ingredients in which a plasticizer and a hardener are included, which directly indicates the polyurethane.

That’s the evidence of the presence of polyurethane in Epoxy Resin PCB.

Polyurethane Present in Epoxy Resin PCB

Is Epoxy Resin PCB Used in the Potting and Encapsulation?

Yes, Epoxy Resin is used in potting and encapsulation of an electric component in a printed circuit. Basically, both terms potting and encapsulation are used interchangeably, having the same meaning.

This is the process in which the shell or pot is filled into the circuit with the help of Epoxy Resin. In the end, it becomes part of the particular electrical component.

At the same time, encapsulation is often a process in which the hardened resin used in potting is removed with the electrical component to be placed in the assembly.

In these processes, the Epoxy Resin protects the assembly and insulates the board circuit permanently. That’s how the electrical components, devices, circuits, and assembly avoid harmful attacks.

Epoxy Resin PCB Used in the Potting and Encapsulation

Uses of Electrical Epoxy Resin PCB

What are the Advantages of Conformal Coating in Epoxy Resin PCB?

In Conformal Coating, a thin polymeric film is applied to the printed circuit board in order to protect all of the electrical components in assembly from an aggressive environment and corrosion.

This conformal coating has lots of benefits to printed board circuits. Let’s have a deep look at these benefits below:

• Increase the resistance power and promotes the insulation
• It can help to eliminate unwanted spaces
• Light-weighted (does not affect you, circuit board)
• With the conformal coating, the assembly will be protected against corrosive attack and chemicals
• Degradation of potential performance has been eliminated
• Conformal coating can eliminate the environmental stress of a PCB’s assembly

There are five types of conformal coating includes Acrylic (Type AR), Silicone (Type SR), Polyurethane (Type UR), Epoxy (Type ER), and Parylene.

What are the Different Materials in the EpoxyResin Circuit Board?

There are six components used as a material to design an Epoxy Resin PCB Circuit Board. These are Prepreg, Laminate, Solder mask, Copper foil, Nomenclature, Final Finish.

The prepreg is the thinnest glass fabric that is smoothly coated with resin, and a special machine called prepreg treaters is used to dry.

Here, the glass is the substrate that holds the resin in place, and the FR-4 Epoxy coated onto the fabric while starting as a liquid.

As the prepreg moves in the machine, it enters into the oven section, where it begins to fry. When it exits the machine, it is dry to touch.

Laminates are also called copper clad. The prepreg sheets play an important role in their production.

They are laminated together with the pressure and heat and with the sheets of copper foil on one or both sides.

Once the filled resin becomes harder, the PCB laminates are like plastic composite, and the sheets of copper foil are embedded on both sides.

The solder mask is used to cover the printed board circuit from the outer layers, which has a green epoxy coating.

Here, the internal circuits are buried under prepreg layers because they have no need to be protected.

But if the external layers wouldn’t be protected, these will cause the problem and corrode over time.

Solder mask is the most useful material there, which highly provides protection to the conductors there outside of the printed board circuit.

Silkscreen or nomenclature are the white letters on the top of the solder mask coating on a printed board circuit.

The lettering of nomenclature will show that every component goes on the board, and sometimes it’ll provide the component orientation as well.

There are variations of colors in solder masks and nomenclature.

Here, green and white color is present while those are most popular and are also suggested by the experts for better efficiency.

Is China a Good Place to Purchase Epoxy Resin PCB?
