Description

technical field [0001] The present invention relates to a circuit board assembly, and in particular to a circuit board assembly capable of improving electromagnetic wave effects. Background technique [0002] In recent years, with the rapid development of the electronic information industry, the application of high-speed circuit boards has become more and more common. At the same time, this also makes the electromagnetic interference (Electromagnetic Interference, EMI) problem in the circuit board design more prominent. [0003] In the traditional technology, bypass capacitors are usually arranged on the circuit board to bypass the radiated high-frequency signal to solve the electromagnetic interference problem of the circuit board. However, after adding the bypass capacitor, although part of the radiated high-frequency signal can be bypassed, it will also destroy the integrity of the signal transmitted in the circuit board, and it is also not conducive to the simplified de...
