Product Description

What Is High TG PCB?

Glass Transition Temperature (Tg) is the critical temperature at which a resin substrate transforms from a hard "glassy state" to a soft "rubber-like state." Below this point, the material retains dimensional stability and mechanical strength; above it, properties decline sharply.

High Tg PCB: PCB substrates with a Tg value of ≥ 150°C are defined as high Tg materials. The Tg of a conventional FR-4 is generally around 130–140°C.

High TG PCB-11

Core Features

Super Heat Resistance

It can withstand the high temperature of lead-free welding (usually over 260°C), and the underlayment structure remains stable in high-temperature environments without delamination or deformation. High Tg PCBs can pass the 288°C tin furnace test without board explosion or copper foil peeling.

Stable Mechanical & Dimensional Properties

The coefficient of thermal expansion (CTE) is lower than conventional plates, reducing warping caused by temperature changes and preventing copper layer cracking at through holes. This is especially critical in multi-layer boards of 8 layers or more, ensuring the reliability of plated through-hole connections.

Outstanding Electrical & Chemical Properties

Most high Tg plates feature a low dielectric constant (e.g., 3.5±0.05 @1GHz) and low dielectric loss (as low as 0.002), reducing high-frequency signal attenuation and crosstalk. They also exhibit strong chemical resistance, remaining stable after wet treatment, chemical immersion, and humid environments.

Common Materials

High Tg PCB boards use high-performance resin substrates. Tg values vary significantly across materials, adapting to different application requirements. Common types are listed below:

Material Tg Value
Rogers RO4350B 280°C
Rogers RO4003C 280°C
Alon 85N 250°C
Isola FR408HR 180°C
Weichuang6 185°C

Key Application Scenarios

Automotive Electronics

BMS systems for new energy vehicles and ECUs in engine compartments generate significant heat. High Tg PCBs operate stably in these environments, ensuring driving safety.

5G & High-Performance Computing

5G base station antennas, optical modules, servers, and switches demand high-frequency signal integrity. The low-loss characteristics of high Tg boards ensure efficient data transmission.

Aerospace & Military

Satellite communication boards and polar radar control boards must withstand extreme temperature ranges from -40°C to 125°C. TG180 substrates enhance thermal cycling tolerance and reduce failure rates.

Medical Electronics

Ultrasound imaging devices and high-temperature sterilized medical equipment rely on high Tg PCB stability under sustained high temperatures to avoid equipment failure impacting diagnosis and treatment.

Key Points of Manufacturing Process

  • 1
    Lamination Process

    Using a precise temperature-pressure curve with vacuum lamination technology, boards are bonded at ~180°C under specific pressure to eliminate air bubbles, enhance Z-axis stability, and ensure inter-layer bonding strength.

  • 2
    Drilling & Impedance Control

    Laser drilling technology achieves hole diameter accuracy of ±25μm, suitable for micro-hole interconnection in multi-layer HDI boards. Impedance tolerances are strictly maintained within ±5% to ensure high-speed signal transmission.

  • 3
    Surface Treatment

    To prevent surface oxidation, tin plating and nickel-gold plating are preferred. Large solder mask windows are opened in pad areas to enhance adhesion between solder and the copper layer.

Frequently Asked Questions (FAQ)

Q What is the difference between High Tg PCB and standard FR-4 PCB?
Standard FR-4 PCBs have a glass transition temperature of approximately 130–140°C, which makes them unsuitable for high-temperature environments. High Tg PCBs have a Tg value of ≥150°C (with some materials reaching up to 280°C), offering superior heat resistance, dimensional stability, and electrical performance. They are designed for demanding applications where standard FR-4 would delaminate, warp, or fail.
Q Can High Tg PCBs be used with lead-free soldering processes?
Yes. High Tg PCBs are specifically designed to withstand the elevated temperatures of lead-free soldering, which typically exceeds 260°C. They can pass the 288°C tin furnace test without board explosion, delamination, or copper foil peeling, making them fully compatible with RoHS-compliant lead-free assembly processes.
Q Which High Tg material should I choose for my application?
Material selection depends on your operating temperature range and performance requirements. For the highest Tg (280°C), Rogers RO4350B or RO4003C are ideal for high-frequency RF applications. For mid-range requirements (180–185°C), Isola FR408HR or Weichuang6 are cost-effective options. For extreme environments, Alon 85N (250°C) provides excellent performance. Our engineering team can recommend the best material based on your specific design requirements.
Q Are High Tg PCBs suitable for multilayer board designs?
Absolutely. High Tg PCBs are especially beneficial for multilayer boards of 8 layers or more. Their lower coefficient of thermal expansion (CTE) reduces warping during thermal cycling and prevents the copper layer at plated through holes (PTH) from cracking — a common failure point in multilayer designs. This makes them the preferred choice for complex HDI multilayer PCB fabrication.
Q What surface finishes are available for High Tg PCBs?
To prevent oxidation and ensure reliable solderability, High Tg PCBs are typically processed with surface finishes such as ENIG (Electroless Nickel Immersion Gold), HASL with lead-free tin plating, or OSP (Organic Solderability Preservative). ENIG is the most commonly recommended option for high-reliability applications due to its flat surface and excellent oxidation resistance.
Q How do High Tg PCBs perform in high-frequency signal applications?
High Tg PCBs — particularly those made from Rogers or Isola materials — offer a low dielectric constant (as low as 3.5±0.05 @1GHz) and very low dielectric loss (as low as 0.002). These properties minimize signal attenuation and crosstalk, making High Tg PCBs ideal for 5G base stations, optical modules, high-speed servers, radar systems, and other applications requiring precise high-frequency signal integrity.
