BT PCB Features

Thermal Stability

You rely on BT PCB for its high thermal stability, which sets it apart from many other printed circuit boards. This high-performance substrate can withstand extreme temperatures, making it a top choice for high-reliability and heat resistance in advanced electronics. When you use BT PCB, you benefit from a material that resists thermal expansion and maintains its shape and function even during rapid temperature changes.

Here’s how BT PCB compares to other PCB materials:

You see that BT PCB offers a glass transition temperature much higher than standard FR-4, which means it can operate at temperatures up to ~200°C. This property ensures reliability under harsh conditions, especially in environments where thermal management is critical. You also notice that BT PCB absorbs less moisture, which helps maintain its performance over time.

Tip: BT PCB’s enhanced thermal conductivity and reduced dimensional expansion help you achieve better thermal management and stability in high-frequency applications.

When you choose BT PCB, you gain:

• Improved reliability in extreme environments

• Reduced dimensional expansion at high temperatures

• Enhanced stability of plated through holes

• Better thermal stress resistance in temperature cycling applications

These properties make BT PCB the preferred option for devices that demand high-reliability and heat resistance, such as automotive and aerospace electronics.

Electrical Properties

You need your PCB to deliver superior electrical performance, especially when working with high-speed signal transmission and high-frequency applications. BT PCB stands out because it maintains excellent electrical insulation, even under extreme conditions. This ensures that your circuits remain stable and efficient, reducing the risk of signal loss or interference.

Let’s compare some key electrical properties:

You benefit from BT PCB’s low dielectric constant (3.38–3.50 at 100 kHz) and low dielectric loss (0.0102–0.0107 at 100 kHz). These properties support high-speed signal transmission and minimize signal attenuation, which is essential for modern communication and computing devices.

When you design high-frequency circuits, you should:

• Keep trace lengths short and avoid sharp bends

• Minimize the number of vias to reduce capacitance and inductance

• Route differential pairs closely together for consistent impedance

• Use uniform trace width and spacing to control impedance

• Select low-loss materials for better signal integrity

BT PCB’s electrical properties make it ideal for high-frequency applications, where signal clarity and reliability matter most.

Mechanical Strength

You expect your PCB to handle physical stress without losing performance. BT PCB delivers outstanding mechanical strength, which is vital for devices exposed to vibration, shock, or repeated thermal cycling. This strength comes from its unique resin system, which provides both rigidity and flexibility where needed.

Here’s how BT PCB compares to other substrates:

You see that BT PCB offers a Young’s modulus of 4.06 GPa, which means it resists bending and deformation. This property, combined with its low moisture absorption, ensures reliability under harsh conditions and supports lead-free soldering processes.

Note: BT PCB’s mechanical durability and thermal stability make it a smart choice for applications that require both strength and long-term reliability.

You find BT PCB used in automotive, aerospace, and telecommunications because its mechanical and thermal stability and mechanical strength support demanding environments. Its properties ensure your devices last longer and perform better, even when exposed to challenging conditions.
