High TG PCB Series


FR-4 refers to a grade of epoxy fiberglass material where the FR stands for “flame retarding”. The TG130 refers to the glass transition temperature and indicates that this material will begin to deform at 130 ℃. FR-4 is the most common substrate material for rigid PCBs, particularly prototypes. In the PCB, the pre-preg and core will be made of this material.


The general median Tg is greater than 150-160 centigrade, As a general rule the higher the Tg, the more stable the material is during the PCB manufacturing process and assembly. If you are not sure about what material you should specify, ask your PCB manufacturer. They know their process and they know what they are capable of.

FR4 High TG170 PCB

FR-4 materials with higher glass transition temperatures are available in the Advanced PCB service. High TG FR-4 (TG170) boards can withstand deformation at higher temperatures of up to 170 ℃ and are suitable for extreme temperature applications. If you want to make multi-layers (more than 10 layers) with blind & buried via.

High TG175 PCB

The typical FR4 TG175 material is Nelco N4000-6, which is a high-Tg epoxy laminate and prepreg system that provides a wide range of performance versatility and ease of processing for demanding high-layer count applications. It has excellent electrical properties for a standard loss material, supporting advanced technology PWB designs, and is suitable for high-layer count, sophisticated PWB designs.

High TG180 PCB

PCBMay manufactures PCBs with Tg value of up to 180°C. Normally the High TG180 PCB is ITEQ 180 and 370HR. When you need high class items, use ITEQ IT180A (TG 180) which is also RoHS compliant. ITEQ IT180A (TG 180) is comparable in quality and to Isola 370HR (TG 180), which are made using a patented high performance 180°C Tg FR-4 multi-functional epoxy resin system.


PTFE materials are suited for high-frequency applications. At RF and Microwave frequencies, the dielectric constant of standard FR-4 Material (approx. 4.5) is often too high, resulting in significant signal loss during transmission across the PCB. Fortunately, PTFE materials boast dielectric constant values as low as 3.5 or below, ideal for overcoming high-speed FR-4 limits.

High TG PCB By Type (5)

  • Rigid-Flex High TG PCB

    We create Rigid-Flex PCBs with all moisture eliminated because the material must be exposed to high temperatures. Rigid-flex PCBs can be used in smartphones, military equipment, and aeronautics.
