FR4 PCB
Send your Gerber and drill files with the required layer count, board thickness, copper weight, surface finish, solder mask color, quantity and delivery target. YC PCB will check manufacturability, testing and optional PCBA requirements before providing a quotation.
What Is FR4 PCB?
FR4 PCB is a rigid circuit board made with fiberglass-reinforced epoxy laminate. It is widely used because it offers a practical balance of cost, mechanical strength, electrical insulation and manufacturability.
Choose FR4 when your product requires a rigid circuit board and does not depend on metal-core heat dissipation, repeated bending or a specialized low-loss RF material. Send the application, operating conditions and PCB files so the material route can be confirmed before production.
FR4 material structure
The finished board combines fiberglass reinforcement, epoxy insulation and copper circuit layers. Specify the layer count, finished thickness, copper weight, Tg requirement and any electrical or mechanical constraints in the RFQ.
FR4 Material PCB
For an accurate FR4 PCB quotation, confirm the finished thickness, copper weight, solder mask, surface finish, operating temperature, mechanical requirements and assembly method.
Fiberglass strength
Fiberglass reinforcement provides the rigidity and dimensional stability needed for drilling, routing, component assembly and service in the finished product.
- Helps reduce warping risk
- Supports routing and drilling
- Suitable for many rigid board shapes
Epoxy insulation
Epoxy resin electrically isolates the copper layers and supports standard rigid PCB manufacturing for general electronic applications.
- Good electrical insulation
- Common in rigid PCB fabrication
- Project review needed for thermal stress
Copper circuit layer
Copper foil is etched into the required circuit pattern. State the copper weight, current load and any high-current areas so trace width and manufacturability can be checked.
- 1 oz is common for many boards
- Custom copper weight can be reviewed
- Electrical testing checks open and short risks

Communication Series 4 Layer FR4 PCB with ENIG
Suitable for communication and control modules that require internal reference planes, higher routing density, stable SMT pads and ENIG surface finish.
FR4 PCB Applications
FR4 PCB is commonly used in lighting controls, industrial electronics, consumer products, power modules and communication equipment. Confirm heat load, current, routing density, operating environment and assembly method before finalizing the material.
LED Aydınlatma
Use FR4 for low-power LED strips, indicators and decorative lighting. For concentrated heat or high-power LEDs, compare aluminum and copper substrate options before approving the design.
Industrial FR4 PCB
Use this route for industrial controllers, drivers and power interfaces that require stable routing, reliable plated holes, electrical testing and repeatable production.
Tüketici Elektroniği
Use FR4 for compact control, connection and power functions where a rigid board, standard assembly process and controlled production cost are required.
Communication Modules
Use 4-layer FR4 when communication electronics require denser routing, dedicated reference planes, fine SMT pads or ENIG finish.
FR4 vs Other PCB Materials
FR4 is suitable for many rigid electronic products. Select another material when the design requires stronger heat transfer, repeated flexing, lower RF loss or specialized high-current construction.
