    impedance matching in hi-tech PCB
    The electronics engineers often encounter impedance matching problems. What the impedance matching is and why we do impedance matching? This article takes you to find out! In electronics, the blocking effect on the circuit is often referred to as impedance. Impedance's unit is ohms, commonly referred to as Z,Z= R+i[ωL–1/(ωC)]. Impedance could adjust the load power and suppress signal reflection.
