High-Tg PCB

High-Tg PCB

FR4 High-TG PCBs are necessary when you need to subject your PCBs to high temperatures. TG is the glass transition temperature of a PCB, and this is the temperature where the PCB transforms from a solid condition to a liquid condition. When PCBs have a glass transition temperature (TG) of more than 170 degrees Celsius, they are called High TG PCBs. The TG value is based on the substrate of the PCB, and if the operating temperature exceeds the TG value, the board will change its state, reducing the functionality of the PCB. High-TG PCBs maintain stability at higher temperatures, and they maintain better chemical and mechanical stability.

Our Experience

We at MKTPCB have more than 10 years of experience fabricating and assembling PCBs for all types of applications and devices. We have an in-house quality assurance team that guarantees that every PCB is made with the highest of standards and capabilities. As a result, we fabricate reliable, high-quality PCBs of all types, including High-TG PCBs. We fabricate High-TG PCBs with FR-4 or other high-quality heat and high temperature resistant TG materials. We know how to find the best solution for the demands of specific applications.

When to Use High-TG PCB Service

You need to use High-TG PCB service when you have components and devices that operate at high temperatures. The TG value of the PCB should be at least 20 to 25 degrees Celsius higher than the anticipated operating temperature of the device. For example, multilayer or HDI PCBs are more compact and have dense circuits, which can lead to high levels of heat dissipation. You will often find High-TG PCBs used in these types to ensure reliability. Increasing the TG of a PCB substrate will also increase heat resistance, moisture resistance, chemical resistance, and the stability of the device. High-TG PCBs are a great solution in any application that has high operating temperatures.

Features of High-TG PCB Service

High-TG PCBs are able to withstand higher operating temperatures inside devices. There are specific materials that increase the heat resistance of the PCB. We use FR4 and FR5 High-TG boards that withstand temperatures up to 180 degrees Celsius. We are able to customize all PCBs to meet the requirements of any designs, including those for the automotive industry and other high temperature electronics applications.

We provide High-TG PCBs and have the following capabilities:

  • Standard IPC2 quality grade
  • Two to 40 layers
  • Quantities of one to 10,000 or more pieces
  • Build time of two days to five weeks

We also have a variety of board thicknesses, sizes, and weights to ensure customizability for any application.
