FR1 PCB By Feature
With full flexibility while having a robust, small form factor, low cost, and easy to use. A flame retardant and self-extinguishing material that can be used as interconnect and internal plane in your circuit boards.
Versatile, flexible and high quality PCB that is used widely in manufacturing and testing applications. FR1 is a one-sided, surface mountable and void-free PCB with excellent solderability of ENIG coating.
It has excellent electrical conductivity and corrosion resistance, as well as low thermal expansion rates, which make it a reliable product for use across many different applications.
Immersion Silver FR1 is a continuous, conductive layer of silver that results in a cost-effective performance and reliability solution for many mixed-signal applications like wireless connectivity, industrial controls, etc.
ENEPIG FR1 PCB also has fine thermal conductivity and can be used to dissipate quite perfectly heat from the circuit so that your components can work safely and with precision.
HASL FR1 is popular bare board material as one of the best PCB materials due to its electro-mechanical properties. HASL features a non-conductive coating that eliminates the need for a separate resin in the solder plating.
What is FR1 Printed Circuit Boards?
FR1 Printed Circuit Boards are a type of circuit board made from fiberglass-reinforced epoxy laminate. FR1 PCBs are hard, flat materials that consist of a thin layer of copper over a non-conductive phenolic resin.
FR1 boards are commonly used in electronics because they can be produced in large quantities quickly and easily. They are usually manufactured by stamping or etching the copper on a surface that has been chemically coated with an insulating material.
FR1 is most often used for applications where there is low demand for heat dissipation, but it is also commonly used in high-end consumer electronics such as smartphones and tablets.
Most Common Type of Copper PCB | FR1 PCB
FR1 PCBs are the most common type of copper PCB on the market. FR1 stands for “flame retardant 1,” and it’s exactly what it sounds like: a flame-retardant, fiberglass-reinforced printed circuit board that can be used for anything from audio equipment to small appliances.
FR1 PCBs are durable, lightweight, and easy to use. They’re also relatively inexpensive compared to other types of PCBs. If you’re looking for a way to make a project more durable or waterproof without breaking the bank, FR1 PCBs are an excellent option.
Difference and Variation of FR1 to other Fire-Resistant PCBs
FR1 is a fire-resistant PCB that has been developed by PCBTok in order to provide customers with an alternative to fire-resistant PCB and other commonly used materials in the manufacturing of printed circuit boards.
Compared to other fire-resistant PCBs, FR1 has several advantages:
- FR1 is more affordable than FR4, which means that it can be more readily substituted for FR4.
- FR1 is easier to process than other fire-resistant materials, making it easier for manufacturers who have never worked with these types of materials before.
- FR1 is lighter than other fire-resistant materials, making it easier for manufacturers who need to work with lightweight boards (such as those being used in smartphones).

FR1 PCB Fabrication
The FR1 PCB board is a material that is designed to be used in the production of environmentally friendly PCB boards. The FR1 is made from resin bonded paper, which is produced with a special binding process to make it more durable than other boards.
The FR1 PCB board is a revolutionary product that has been created by PCBTok to meet the needs of those who want to use environmentally friendly products in their daily lives.
The FR1 PCB has an excellent flame retardant rating, which means it can withstand extreme temperatures and high heat without catching fire. This is important for electronic devices that use heat to function, such as laptops and cellphones.
The FR1 PCBs we offer are manufactured with flame retardant materials. The FR1 PCBs we offer are also RoHS compliant, meaning they do not contain hazardous substances such as lead, mercury, and cadmium.
OEM & ODM FR1 PCB Applications
FR1 is a high-performance PCB for wearable applications. This can be used for IoT wearables, such as trackers, smart shoes, and smart clothing.
Our FR-1 boards are lead-free, ROHS compliant and are manufactured to meet or exceed all industry requirements, especially if they have robots.
The FR1 PCB is a high quality, easy to manufacture board that allows you to create a professional product using Arduino boards and other parts.
The FR1 is a flexible PCB which is used in mobile-phone display devices and other apparatuses that use touch functions.
The FR1 PCB is an ideal board to make your tablets. The FR1 PCB has everything you need to get started on manufacturing modular smart devices.
