China Wholesale Prototype Pcb Quotes - 8 Layer High Tg Impedance Control Fine Pitch PCB – Huihe

Advantages Of High Tg PCB

1. Higher stability: if the Tg of PCB is increased, it will automatically improve the heat resistance, chemical resistance, moisture resistance and device stability.

2.Withstand high power density design: if the device has high power density and fairly high calorific value, then high Tg PCB will be a good solution for heat management.

3.When reducing the heat generation of ordinary boards, larger printed circuit boards can be used to change the design and power requirements of the equipment, and high Tg PCB can also be used.

4. Ideal choice for multilayer and HDI PCB: because multilayer and HDI PCB are more compact and circuit intensive, it will lead to a high level of heat dissipation. Therefore, high Tg PCB is usually used for multilayer and HDI PCB to ensure the reliability of PCB manufacturing.

About The Impedance Control

In the case of transmission of high frequency signals, the controlled impedance helps to ensure that the signal does not decay significantly during transmission. In essence, controlled impedance refers to the matching of the material properties of the substrate to the characteristics of the line/dielectric layer to ensure that the impedance value of the line signal is within the tolerance of the reference value. Controlled impedance PCBs provide reliable and consistent high frequency characteristics.
