II.Indispensable basic knowledge about hardware for design of high-performance PCB
Since the design of PCB comes in an age of high-speed design, the knowledge about signal integrity based on the theory of transmission line comes into vogue instead of the basic knowledge in hardware. It has been pointed out that after ten years the design in hardware includes only front end and back end (front end refers to IC design while back end refers to PCB design), so the design is easily completed if a system engineer pieces them up. This would cast doubt on the necessity to study basic knowledge of hardware. In fact, the engineers, whether IC or PCB engineer, shall all master such knowledge as R, L, C and basic gate circuits.
The design of high-performance PCB cannot do without basic knowledge of power supply as well as general knowledge of FPGA. Even the analysis of signal integrity based on the theory of transmission line also researches into the elements like R, L and C.
The design engineers of PCB shall possess basic knowledge of circuits, such as high and low frequency, digital circuit, microwave, electromagnetic field and wave etc. Having a good knowledge of basic functions of products designed as well as basic knowledge in hardware is a basic requirement for design of high-performance PCB.
