What Is FR4?

Standard FR4 Properties

You see fr4 used in lots of pcb designs. Fr4 means "Flame Retardant 4." It is made from fiberglass cloth and epoxy resin. This makes a strong and steady base for your pcb. Fr4 can handle heat and does not soak up water. It also keeps electricity from leaking. A standard fr4 pcb has a glass transition temperature (TG) of about 130°C to 140°C. This lets your pcb work at normal heat levels without bending or breaking.

Tip: Fr4 gives your pcb good strength, trust, and saves money. You can use it for most regular electronics.

Common Uses

You find fr4 in many pcb projects. Most home electronics use standard fr4 for strength and good work. You see fr4 in computers, TVs, and phones. Many machines in factories use fr4 for their control boards. If your project does not need to handle high heat, standard fr4 is a good pick. You can use this material for simple gadgets, toys, and some car electronics. Fr4 is the top choice for pcb making because it works well and does not cost too much.

What Are High TG PCBs?

High TG PCB Definition

You may wonder what makes high tg pcb different from regular pcb materials. High tg pcb stands for "high glass transition temperature printed circuit board." This means the pcb can handle much higher heat before it starts to soften or lose shape. In most cases, a high tg pcb has a glass transition temperature above 170°C. You use high tg pcbs when your project needs to work in places with a lot of heat or when the pcb faces heavy electrical loads. These boards keep their strength and shape even when the temperature rises. You get better thermal stability with high tg pcb, so your electronics stay safe and reliable.

Key Features

High tg pcbs offer several important features that help your project succeed:

• Higher Heat Resistance: High tg pcb can work in hot environments without breaking down.

• Improved Thermal Conductivity: You get better heat flow through the pcb, which helps prevent overheating.

• Strong Mechanical Strength: High tg pcbs do not warp or crack easily, even under stress.

• Reliable Performance: These boards keep working well, even if you use them for a long time or in tough conditions.

Note: You should choose high tg pcbs if your design needs extra protection from heat or if you use high-power parts. These boards give you peace of mind because they offer both thermal stability and strong thermal conductivity.

Key Differences

Thermal Performance

You want your pcb to handle heat well. Standard FR4 works for most projects, but it starts to soften when the temperature gets close to 130°C.
