                How to ensure that the PCB circuit board can operate under high temperature?

                Below is about the board need long-term work under 150 ℃, can meet the requirements?

                When it comes to temperature, we will talk about the selection of Tg value in PCB board. First of all,Tg value refers to the CORE glass conversion temperature, which can be understood as the softening temperature of the board.

                About 130-140 degrees Celsius, you can use the common FR-4 plate Tg value

                For the temperature of about 170 degrees Celsius, the Tg value of the plate in the fr-4 high-temperature ladder section can be used. Generally, it is recommended to use the Tg170 value in the factory for a long time under such a temperature with high stability

                For temperatures of about 260 degrees Celsius, the Tg value of the polyimide material is used

                About customers work under 150 ℃ high temperature for a long time, our engineer suggested that "in order to ensure the stability of the product suggest choosing raw benefit TG170 plank, can be resistant to high temperature of 150 degrees for a long time"

                As for the thickness of PCB board, it is increased according to customer requirements, and the thickness can be processed.
