What Are The Advtanges Of High Tg PCBs?
At present, there are three kinds of Tg values of PCB board, which are the most common ones, namely ordinary Tg130, medium Tg150 and high Tg170. The number represents the temperature. High Tg PCBs are generally used TG170 board. In other words, Tg value represents the heat resistance of PCB board. Common Tg board will soften and deform at high temperature, and the mechanical and electrical properties of PCB board will decrease rapidly after undergoing changes in hardness and strength, which may affect the service life of PCB at least, or lead to scrap of PCB at most.
High Tg PCBs have excellent heat resistance, moisture resistance and mechanical properties. With the rapid development of electronic industry, high Tg materials are also widely used in computers, communication equipment, precision instruments, instrumentation and other fields.
1. Higher stability: If the Tg of PCB substrate is increased, it will automatically improve heat resistance, chemical resistance, moisture resistance and device stability.
2, withstand high power density design: if the device has high power density and comparatively high calorific value, then high Tg PCBs will be a good solution for heat management.
3. When reducing heat generation from ordinary boards, larger printed circuit boards can be used to change the design and power requirements of the equipment, and high Tg PCBs can also be used.
4. Ideal for multilayer and HDI PCBs: Because multilayer and HDI PCBs are more compact and have dense circuits, they will result in elevated levels of heat dissipation. Therefore, high tg PCBs are commonly used in multilayer and HDI PCBs to ensure PCB manufacturing reliability.
