WHAT IS FR4 PCB?

FR4 PCB refers to a type of printed circuit board (PCB) made from a specific grade of fiberglass-reinforced epoxy laminate material known as FR4. FR4 is the most widely used PCB material due to its excellent electrical and mechanical properties.

The term "FR4" is derived from the NEMA grade designation for the material, where "FR" stands for "fire retardant" and "4" refers to the specific resin system used. The resin in FR4 is flame retardant, making it self-extinguishing and offering a certain level of fire resistance.

WHEN TO USE FR4

WHEN TO USE FR4 Many electronics applications choose to use the epoxy-based FR4 board. Their strength, reliability and relatively low cost make FR4 epoxy substrates a logical default choice for electronics engineers. However, FR4 isn’t ideal for all situations, especially high-frequency designs. For these designs, high-frequency laminates tend to be a more common choice.Cost: FR4 Will Be Cheaper
FR4 material is a very common PCB base, primarily for its relatively low cost.   High-frequency laminates, on the other hand, are considerably higher in price, which is a significant drawback for cost-concerned designers and manufacturers.   This is the primary limiting factor for companies when choosing between FR4 and high-frequency laminates.
Signal Loss: Lower Df Leads to Lower Signal Loss
Signal loss is, in many cases, a critical part of a PCB design, especially in high-frequency situations where signal loss is more of a problem.   For these designs, FR4 is not an ideal choice — FR4 has a higher Df, or dissipation factor, than high-frequency laminates.   This means FR4 circuits will suffer more signal loss than an identical circuit on a high-frequency laminate.
The Df of FR4 is around 0.020, while the Df of most high-frequency laminates is around 0.004, a fourth of FR4’s Df.   The lower the Df, the less signal loss overall.   The other issue is the Df of FR4 increases as a signal’s frequency increases, meaning as the frequency of the signal increases, more signal loss occurs.   Since high-frequency laminates have more stable Df characteristics, they experience less loss at higher frequencies.
Impedance Stability: Dk Stability Matters
Stable impedance is another important factor for many designs, as it often means more predictable performance, especially for larger circuits or high-frequency designs.   Again in this area, FR4 and high-frequency laminates offer different results.   Maintaining stable impedance requires a material to maintain a stable Dk, or dielectric constant, across the entire material as the temperature of the material changes.
