FR4 Material Types

FR-4 has many different variations depending on the thickness of the material and chemical properties, such as the standard FR-4 and G10. The following list shows some common designations for FR4 PCB materials.

Standard FR4: This is the most common type of FR4. It provides good mechanical and moisture resistance, with heat resistance of about 140℃ to 150℃.

FR4 With High Tg: FR4 with high Tg is suitable for applications requiring high thermal cycling and temperatures greater than 150℃. Standard FR4 is limited to around 150℃, while FR4 with high Tg can withstand much higher temperatures.

FR4 With High CTI: FR4 with high CTI (Chemical Thermal Interaction) has better thermal conductivity than regular FR4 material. It has a comparative tracking index higher than 600 Volts.

FR4 without copper laminate: FR4 without copper laminate is a non-conductive material with excellent mechanical strength. It is mainly suitable for insulating boards and board supports.

FR4 G10: FR-4 G10 is a solid core material with excellent mechanical properties, high thermal shock resistance, excellent dielectric properties, and good electrical insulation properties.

The requirements of high frequency pcb material:

(1) the dielectric constant (Dk) must be very stable

(2) Dielectric loss (Df) must be small, which mainly affects the quality of signal transmission, the smaller the dielectric loss so that the signal loss is also smaller.

(3) and copper foil thermal expansion coefficient as far as possible, because inconsistencies in the change in the cold and heat caused by copper foil separation.

(4) low water absorption, high water absorption will be affected in the damp when the dielectric constant and dielectric loss.

(5) Other heat resistance, chemical resistance, impact strength, peel strength, etc. must also be good.
