• High TG PCBs cost more at first. But they save money later by needing less fixing and fewer new parts.

High TG PCB Properties

What Is Glass Transition Temperature?

You should know about glass transition temperature, or Tg, when using fr-4 boards. Tg is the temperature where fr-4 changes from hard to soft. If the heat goes above Tg, fr-4 can bend or twist. This might cause problems like layers coming apart or cracks in your pcb. High tg pcb means the Tg is much higher than normal. Most regular fr-4 boards have a Tg between 130°C and 140°C. High tg fr-4 pcb types have Tg values of 170°C, 180°C, or even more. Some very high-temperature pcbs can have Tg values over 190°C.

Here is a table that shows the Tg ranges for different pcb types:

You can also see the difference in Tg values in this chart:

When you use high tg fr-4 pcb, it works better in high heat. The fr-4 stays strong and does not get soft or lose its shape, even when it is hot.

• Dashboards show info to the driver.

You pick high tg pcb for these jobs because it can take big heat changes and strong shaking. High tg materials have a Tg of 170°C or more. This keeps your board steady during heat cycles. The board does not bend or break when the heat goes up and down.

High tg materials also help your pcb stay cool. They keep the board working at least 25°C below the glass transition temperature. This stops the board from getting soft or failing when the engine or other parts get hot.

Performance Benefits

When you use high tg pcb in cars, you get better results and longer life. These boards have strong heat stability and keep their shape under stress. Here is a table that compares high tg pcb with regular boards:

High tg pcb lowers the chance of bending and insulation problems. You avoid cracks and material wear, especially in engine controllers where heat can go over 125°C. Regular boards often fail here because they cannot take the heat.

You get more reliable electronics in your car. Using high tg pcb helps you lower breakdowns and save on repairs. Your car works better, and you spend less time fixing things.

Tip: Always pick high tg pcb for engine controllers and other tough car systems. This gives you the best mix of safety, performance, and value.

Selecting High TG PCB

Temperature and Reliability

You need to check some features if you want your pcb to last in tough places. Look for these important things:

• Glass Transition Temperature (Tg): This shows when the resin gets soft. A higher Tg keeps your board safer from heat.

• Coefficient of Thermal Expansion (CTE): Low and steady CTE keeps your vias strong. It helps your board stay reliable.

• Decomposition Temperature (Td): This stops the board from breaking during hot soldering.

• T288: This tells you how well the laminate stays together at high heat.

• Conductive Anodic Filament (CAF) Resistance: This protects your circuits from inside problems.

• Dielectric Constant and Loss Tangent: These keep your signals clear, even when the board is hot.

• Moisture Absorption: Low moisture means less risk of layers coming apart during soldering.

Tip: Always match the board’s Tg and Td to your highest working temperature. This helps your pcb stay strong and safe.

Cost and Supplier Choice

High-performance boards cost more than regular ones. The price is higher because the materials are better and last longer. When you pick a supplier, ask if they have experience with tough boards. Make sure they follow safety rules and can show test results. Some suppliers use safer materials for the planet, like polyimide or LCP. These do not have harmful flame retardants. These boards also use less energy to make and create less waste.
