With the increase of integrated circuit switch rate and PCB density, signal integrity has become one of the problems must be concerned in high-speed PCB design. How to fully consider EMC (Electromagnetic compatibility) and take effective measures has been a key factor of a system design. Based on the consideration of EMC, the author put forward some aspects in designing high-speed PCB. The optimized PCB design rules have steady and credible performance, the development period is shortened and the cost is reduced. The conclusions drawn from the dissertation are helpful to the design of high-speed PCB.

Integrity Analysis

RF System-in-Package (SiP) has become a viable packaging platform, which offers great flexibility to integrate ICs with different processes and different architects. With operating frequency becoming higher and multiple available technologies embedded in one package, the system could fail due to the undesired noise coupling resulted from the close proximity of the components. Therefore, the design methodology with signal integrity (SI), power integrity (PI), and electromagnetic compatibility (EMC) analysis becomes essential to tackle the SiP integration issues. The paper presents a RF SiP design methodology with SI/PI/EMC simulations, which greatly reduces the design time and enables first-pass success.

High Speed Data

<p>5G wireless network technology is going operate within the environment of other electrical, electronic and electromagnetic devices, components and systems, with capability of high speed data connectivity acting as network transceiver stations with Massive MIMO for Internet of Things (IoT). Considering the level of interoperability, electromagnetic Interference and electromagnetic compatibility to avoid electromagnetic pulse effects (EMP) which is capable of not only causing network malfunctions but total devices and equipments failure in mission critical operations, like hospital MRI scan machines, security profiling and data handling or even personal healthcare devices like heart pacemaker. Electromagnetic energy coupling in PCB due to: radiation, reflection and Crosstalk generates reliability challenges affecting Signal Integrity between traces of multilayer boards stalks, power bus and packaging creating Electromagnetic interference (EMI) in PCB leading false clock response to system failure. Above were considered very essential when deploying 5G wireless network facility as presented in this paper. </p>
