Megtron7 PCB--Panasonic automotive and Industrial Systems Corporation announced on May 28, 2014 that it has developed a low loss multilayer substrate material "Megtron 7" for high-end servers, routers and supercomputers with large capacity and high-speed transmission. The relative permittivity of the product is 3.3 (at 1GHz) and the dielectric loss tangent is 0.001 (at 1GHz). Compared with the original product "Megtron 6", the transmission loss is reduced by 20%.
In the design of 13 layer R5775G high-speed PCB, the main problems that must be considered are signal integrity, electromagnetic compatibility and thermal noise. Generally, when the signal frequency is higher than 30MHz, the signal distortion must be prevented. When the frequency is higher than 66MHz, the signal integrity must be analyzed.
Polyimide products are highly demanded due to their huge heat resistance, which leads to their use in everything from fuel cells to military applications and printed circuit boards. The following is about VT901 PCB related, I hope to help you better understand VT-901 PCB.
