What is FR-4?

FR4, also written as FR-4, is both a name and a standard rating. The name is applied to the fiberglass-reinforced epoxy-laminated sheets used in printed circuit board manufacturing. However, the name also functions as a grade used to rate epoxy laminate sheets. The designation essentially indicates the base quality of a laminate sheet, meaning a variety of sheet materials and designs fall under the FR4 rating. The “FR” in the name stands for flame retardant, while the 4 differentiates the material from others of the same class.

Types of FR-4 PCB Material

There are four different types of FR-4 material available in the market based on individual properties, they are listed:
Standard FR-4
Standard FR-4 refers to the normal material, with heat resistance ranging from 150-160 Celsius.
High CTI FR-4
The Comparative Tracking Index is the limit to which the FR-4 or any other insulating material can resist the unwanted current flowing between the tracks on the printed circuit board.  The CTI value indicates how resistive PCB base material is against unpleasant environmental and electrical conditions such as moisture and leakages on board.  The high CTI material with a maximum value of 600 voltages ensures that the base is more resistant and can withstand harsh environmental and electrical conditions.
High TG FR-4
High TG FR-4 stands for high glass transition temperature.        PCBs made with high glass transition temperature FR-4 material have the ability to resist and maintain their shape at a temperature of 170 ℃.        In this type of base material, Higher TG is achieved through extra-efficient lamination.        PCBs made with high TG FR-4 material have the ability to resist and maintain their shape at a temperature of 170 ℃.        The standard Fr-4 material is a great insulator and flame retardant, but still, it has some limits when exposed to high power, voltage, or heat.        If a certain limit exceeds, the materials insulating properties can get weakened.        It can start conducting electricity instead of insulating it.        Thereby high Tg FR-4 is used to avoid these unwanted circumstances.
FR-4 with no laminated Copper
This type of FR-4 is a little different with distinct functions.        As the name itself explain that this type of material has no copper lamination on it and, therefore, is used to insulate and support other boards, etc.
