          With the continuous advancement and development of automotive technology, electronic systems are being used more and more widely in automobiles. Many key components in automobiles, such as the engine control unit (ECU), power management system, and sensors, rely on high-performance PCBs. Among them, high TG PCBs play a vital role in automotive engines due to its excellent high-temperature resistance.   What is High TG PCB? When the temperature rises to a certain critical value, the PCB substrate will change from a glass state to a rubber state. The critical value of this temperature is the TG value. High TG PCBs refer to those circuit boards whose glass transition temperature is higher than that of regular PCBs. Usually, the TG value of standard PCBs is around 130 ℃ , while the TG value of high TG PCBs is 170 ℃  or even higher.     Application of High TG PCB in Automotive Engines When an automotive engine is running, it will ge...

When the temperature rises to a certain critical value, the PCB substrate will change from a glass state to a rubber state.  The critical value of this temperature is the Tg value, so why use a high Tg PCB, and what are the specific advantages?   1.  H eat  R esistance The high-density mounting technology represented by SMT and CMT makes the PCB more and more inseparable from the high heat resistance support of the base material in terms of small aperture, circuit refinement and thinning. Ordinary Tg boards will soften and deform at high temperatures, while high Tg PCB have better heat resistance and can still maintain excellent physical and mechanical properties under high temperature conditions.     2.  M oisture  R esistance Moisture is destructive to the PCB and can greatly reduce the insulation resistance between conductors . Compared with ordinary PCB, high Tg PCB have better moisture resistance.     3. Stability With the deve...
