High-frequency choke: When wiring the high-frequency circuit board in the high-frequency PCB design, a high-frequency choke device must be connected when the digital ground, analog ground, etc. are connected to the common ground line. Generally, it is a high-frequency ferrite bead with a wire passing through the center hol
According to the rule of thumb, four-layer boards are usually used in high-density and high-frequency situations. Multi-layer PCBs are more than 20DB better than two-layer boards in terms of EMC. Under the condition of a four-layer board, a complete ground plane and a complete power plane can often be used. Under this condition, it is only necessary to connect the ground wires of the circuits divided into several groups to the ground plane, and the working noise is specially handled
With the continuous development of science and technology, the functional requirements of electronic devices are also constantly increasing. In order to meet this demand, HDI (High Density Interconnect) circuit boards came into being. HDI circuit boards have attracted much attention for their high density, high performance and high reliability, and have become an important bridge connecting future technologies.
