> Single-sided PCB / Single-layer PCB

> Double-sided PCB / Double-layer PCB

> Multilayer PCB

> High glass flow temperature value (Tg)

> High temperature durability

> Long delamination durability

> Low Z axis expansion (CTE)

> High temperature resistance: High Tg PCBs have a glass transition temperature greater than 170°C, which is significantly higher than standard FR-4 PCBs, which have a Tg of around 130-140°C. For example, a study conducted by a PCB manufacturer showed that 

High Tg PCBs maintained their mechanical strength and electrical properties after being subjected to temperatures up to 200°C for 1000 hours.

> High reliability: High Tg PCBs have excellent dimensional stability, which means they are less likely to warp or deform under stress. In a study conducted by a PCB manufacturer, High Tg PCBs showed no signs of delamination, warping, or cracking after thermal stress testing, which involves subjecting the PCB to high temperatures.

> Reduced signal distortion: High Tg PCBs have a lower coefficient of thermal expansion (CTE) than standard FR-4 PCBs. For example, a study conducted by a PCB manufacturer showed that the CTE of High Tg PCBs was around 10-15 ppm/°C, compared to around 16-18 ppm/°C for standard FR-4 PCBs. This means that High Tg PCBs are less likely to experience changes in dimensions or shape when exposed to temperature fluctuations, which can cause signal distortion.

> Improved performance at high frequencies: High Tg PCBs have a lower dielectric constant and loss tangent than standard FR-4 PCBs. For example, a study conducted by a PCB manufacturer showed that the dielectric constant of High Tg PCBs was around 3.9, compared to around 4.4 for standard FR-4 PCBs. This means that High Tg PCBs can maintain signal integrity at higher frequencies, which is important for applications that require high-speed data transmission.

> Suitable for specialized industries: High Tg PCBs are often used in specialized industries that require high-temperature resistance, such as automotive electronics, aerospace, and medical devices. High Tg PCBs are also suitable for applications that require high-reliability, such as military and defense.

> Environmentally friendly: High Tg PCBs are often manufactured with lead-free materials, which makes them more environmentally friendly than standard FR-4 PCBs. For example, a study conducted by a PCB manufacturer showed that High Tg PCBs can meet RoHS and WEEE directives, which regulate the use of hazardous substances in electronic products.

> Automotive electronics: High Tg PCBs are used in automotive electronics, such as engine control units, transmission control units, and ABS systems. These systems operate in high-temperature environments and require PCBs that can withstand extreme temperatures without losing their mechanical or electrical properties.

> Aerospace: High Tg PCBs are used in aerospace applications, such as satellites, avionics, and communication systems. These applications require PCBs that can withstand the harsh conditions of space and high-altitude environments, including extreme temperatures and radiation exposure.

> Medical devices: High Tg PCBs are used in medical devices, such as pacemakers, implantable defibrillators, and medical imaging equipment. These devices require PCBs that are reliable and can withstand the heat generated by the components.

> Industrial automation: High Tg PCBs are used in industrial automation applications, such as robotics, machine control, and motor drives. These applications require PCBs that can withstand high temperatures and provide excellent electrical performance.

> Military and defense: High Tg PCBs are used in military and defense applications, such as weapons systems, radar, and communication equipment. These applications require PCBs that are reliable and can withstand harsh environments, including extreme temperatures and vibration.

> Consumer electronics: High Tg PCBs are also used in consumer electronics, such as smartphones, tablets, and laptops. These applications require PCBs that can provide high performance and reliability while minimizing the size and weight of the device.

> FR-4 High Tg: This is a modified version of standard FR-4 laminates, which are made from woven glass fabric impregnated with an epoxy resin. FR-4 High Tg has a higher Tg (typically around 170-180°C) than standard FR-4 (typically around 130-140°C) due to the addition of a high-Tg resin system.

> Polyimide (PI): Polyimide is a high-temperature resistant material that can withstand temperatures up to 260°C. It is commonly used in aerospace and military applications where high-temperature resistance is critical.

> BT Epoxy: BT (Bismaleimide Triazine) epoxy is a thermoset resin system that has a Tg of around 200°C. It is commonly used in high-temperature applications, such as automotive electronics and aerospace.

> PTFE: PTFE (Polytetrafluoroethylene) is a high-performance polymer that has a low dielectric constant and loss tangent. It is commonly used in high-frequency applications, such as radar and communication systems.

> Ceramic filled materials: Some High Tg PCB materials are filled with ceramic particles to enhance their thermal conductivity and improve their thermal stability. These materials are commonly used in LED lighting, power electronics, and high-current applications.

> Material selection: The choice of high-Tg materials is critical for producing high-performance circuit boards. High-Tg materials have a higher glass transition temperature than standard FR-4 laminates, which makes them more resistant to heat and helps to maintain their mechanical and electrical properties at high temperatures.

> Increased copper thickness: Increasing the thickness of the copper layers in a PCB can help to dissipate heat and reduce thermal stress on the board. This is especially important in high-power applications where the board is exposed to high temperatures and current densities.

> Controlled impedance: Impedance control is crucial for high-speed digital circuits and high-frequency analog circuits. By controlling the impedance of the PCB traces, designers can minimize signal reflections and ensure reliable signal transmission.

> Via-in-pad technology: Via-in-pad technology is a technique where vias are placed directly under surface-mount components. This allows for better heat dissipation and improves the electrical performance of the board by reducing signal delay and crosstalk.

> Thermal management techniques: To mitigate the effects of high temperatures on the board, thermal management techniques such as heat sinks, thermal vias, and thermal pads can be used to dissipate heat and maintain a stable operating temperature.
