Product Details Data Sheet

WHAT IS PCB TG

When the temperature gets high enough, the PCB substrate that consists of glass fiber turns soft. The critICal temperature at which the PCB substrate turns from the solid-state to the liquid state is the PCB TG (glass transition temperature). In other words, PCB TG is the highest temperature at which the PCB FR4 substrate keeps rigid.

According to the different TG values, we classify FR4 PCBs into normal TG PCBs, medium TG PCBs, and High TG PCBs: (DSC)

PCB TG Types
TG Values (DSC)
Applications
Normal TG PCBs
130℃, 135℃, 140℃
Computer, communication equipment, instrumentation, game player, TV, VCR, LCD, etc.
Medium TG PCBs
150℃, 155℃
Computer, communication equipment, automotive, consumer electronics, electronic game machine, heavy copper applications, etc.
High TG PCBs
170℃, 180℃, 185℃
Automotive, medical, aerOSPace & defense, industrial control, routers, servers, workstations, precision instruments, power supply, CPU, consumer electronics, etc.

The higher TG of the PCB laminates, the higher the temperature range that the FR4 PCB can properly work in. When the PCB temperature goes beyond the glass transition point, the PCB turns soft and deforms. In this case, the PCB mechanical and electrical performances worsen, and the circuit board becomes unreliable.

Note
When the temperature is higher than the TG value, the PCB material gets soft gradually. If the resin in the PCB doesn't decompose, when the temperature gets lower than the TG value, the PCB goes back without changing.

TG 180 PCB VS TG 150 PCB VS TG 140 PCB

The PCB HERO editor chooses Ventec's three laminates to make a comparison between TG 180 PCB, TG 150 PCB, and TG 140 PCB.

  • The high TG FR4 laminate VT-47: TG 180℃, 5% weight loss Td 355℃, total expansion Z-axis CTE 2.3%

  • The medium TG FR4 laminate VT-42S: TG 150℃, 5% weight loss Td 315℃, total expansion Z-axis CTE 3.75%

  • The normal TG FR4 laminate VT-42: TG 140℃, 5% weight loss Td 310℃, total expansion Z-axis CTE 3.75%
