hard disk 1TB Do DDR designs require a back drill
hard drives SSD OEM hard disk 1TB back drill hard disk 1TB, believe to engage no strangers to PCB design or processing. We know that hard disk 1TB, this process is now more widely used in the design of high-speed serial channels above 10G, its role is mainly to solve the problem of sharp attenuation of high-frequency energy caused by the long via stub, the smaller the via stub, the higher the frequency band of sharp attenuation, so we will focus on it in high-speed design. We can also get the relationship between stub and the return loss insertion curve through 2D or 3D simulation of the vias, as shown in the following figure:
