What is an Epoxy Resin PCB?
You need to understand the two elements of this term, which are:
Epoxy Resin and Printed Circuit Boards.
Epoxy Resin is a raw material for Copper Clad Laminate
Printed circuit boards, using conductive lines, make electronic connections alive.
An Epoxy Resin PCB is then defined as a PCB that is made using epoxy resin.
There are many types of epoxy resin material,
So there are many types of this kind of PCB.
Where to Obtain Epoxy Resin Circuit Boards?
When using different types of epoxy resin for their corresponding PCB products,
There are guidelines that must be followed.
You have two options: you can handle the challenging work yourself,
Or you can let a qualified PCB manufacturer handle it.
Whatever your requirements, PCBTok is a reliable option for your company.
For all of your PCB needs, we provide you with tangible results!
Did you know that we can fabricate any layer of Build Up Multilayer board made of epoxy resin for a reasonable price?
Epoxy Resin PCB By Feature
With this sub-classification, the materials G-10, G-11 (glass composite), FR4, and FR5 are included, all flame retardant.
When using epoxy resin for power or high voltage applications, high Tg is important because it can withstand 180 degrees Celsius.
The flex PCB category, or FPC, uses polyimide epoxy resin. Polyimide is utilized because it is compatible with a variety of substrates.
Epoxy Resin used for HDI PCB must ultimately increase track density in accordance with prevailing semiconductor industry standards.
What is Epoxy Resin in Circuit Boards?
The main element of the copper clad laminate on PCBs is the epoxy resin material.
This material is used so that the board will be electrically conductive.
The epoxy resin material, whether fiberglass-based or paper-based is subject to lamination.
During the lamination process, the epoxy resin itself melts into the cladding.
The choice of epoxy resin is up to the PCB designer.
But in doing so, the designer must weigh price range vs. epoxy resin material characteristics.
Purpose of Using Epoxy Resin on PCB
The main answer is, epoxy resin is a form or protection.
Another way of saying it is the epoxy resin is a form of insulation on circuit boards.
But protection for what?
The following things can harm a PCB when the epoxy resin is weak or wrongly applied.:
- Excessive heat – can happen when the end device is in hot environs
- Vibration – when the end device is inside a gadget that has engine issues
- Shock – as in the case when the end device is dropped
- Temperature changes – e.g. fluctuating weather
What are the Types of Epoxy Resin PCB?
The types of epoxy resin material determine what type of Epoxy Resin PCB it is. There are numerous options for epoxy resin materials due to the large number of customers:
- Fiberglass-reinforced (i.e. FR4 or FR5)
- Paper-based epoxy resin
- Composite epoxy resin like CEM-1 or CEM-3
- High Tg, High CTI epoxy resin
- Lead-free options like ceramic variants
Even if there is an extensive choice, there is no doubt that the FR4 material will prevail.
It’s because it is flame-retardant, and strong due to its reinforced fiberglass content. It is most economical too.

Epoxy Resin PCB Fabrication
There is some clarification of the terms so that you are aware of the distinction:
- Another name for copper cladding laminate is CCL. This serves as the foundation for all PCBs.
- Copper cladding on its own will not suffice. Without reinforcement, which the epoxy resin can provide, it is weak.
- The epoxy resin acts as the strengthener, insulator and protector of the PCB base
You should know that the customer depends on the PCB raw materials to ensure that the board functions optimally.
There are some current trends in the application of this copper cladding raw material that are noteworthy:
- There is a market for lead-free compatible PCBs or lead-free PCB due to the directives by the EU and other nations for environmentally friendly PCB material.
- For radar or microstrip applications, many customers sporadically require PTFE or epoxy resin filled with ceramic.
- Additionally, mobile phones are in demand for BT (Bismaleimide Triazine) epoxy resin.
What is best for each customer depends on the device’s PCB schematic.
